Ten feasible sequence patterns of authentication protocol with TIP and 5 sequence patterns without TFP are gained. These gained sequence patterns meet the requirements for identity authentication, and basically cover almost all the authentication protocols with TFP and without TFP at present. All of the sequence patterns gained are classified into unilateral or bilateral authentication. Then, according to the sequence symmetry, several good sequence patterns with TFP are evaluated. The accompolished results can provide a reference to design of new identity authentication protocols.展开更多

However, wireless communications over open-access environments face many security andprivacy issues that may affect deployment of large-scale VANETs. Researchershave proposed different protocols to address security and privacy issues in aVANET, and in this study we cryptanalyze some of the privacy preservingprotocols to show that all existing protocols are vulnerable to the Sybilattack. The Sybil attack can be used by malicious actors to create fakeidentities that impair existing protocols, which allows them to imitate trafficcongestion or at worse cause an accident that may result in the loss of humanlife. This vulnerability exists because those protocols store vehicle identitiesin an encrypted form, and it is not possible to search over the encryptedidentities to find fake vehicles. This attack is serious in nature and veryprevalent for privacy-preserving protocols. To cope with this kind of attack,we propose a novel and practical protocol that uses Public key encryptionwith an equality test (PKEET) to search over the encrypted identities withoutleaking any information, and eventually eliminate the Sybil attack. Theproposed approach improves security and at the same time maintains privacyin VANET. Our performance analysis indicates that the proposed protocoloutperforms state-of-the-art protocols: The proposed beacon generation timeis constant compared to a linear increase in existing protocols, with beaconverification shown to be faster by 7.908%. Our communicational analysisshows that the proposed protocol with a beacon size of 322 bytes has the leastcommunicational overhead compared to other state-of-the-art protocols.展开更多

Lightweight authentication is considered as one of the most effective methods to ensure the security in the RFID system. Many light-weight authentication protocols use Hash function and pseudorandom generator to ensure the anonymity and confidential communication of the RFID system. But these protocols do not provide such security as they claimed. By analyzing some typical Hash-based RFID authentication protocols, it is found that they are vulnerable to some common attacks. Many protocols cannot resist tracing attack and de-synchronization attack. Some protocols cannot provide forward security. Gy?z? Gódor and Sándor Imre proposed a Hash-based authentication protocol and they claimed their protocol could resist the well-known attacks. But by constructing some different attack scenarios, their protocol is shown to be vulnerable to tracing attack and de-synchronization attack. Based on the analysis for the Hash-based authentication protocols, some feasible suggestions are proposed to improve the security of the RFID authentication protocols.展开更多

However, such IoT based smart industriesneed internet connectivity and interoperability which makes them susceptibleto numerous cyber-attacks due to the scarcity of computational resourcesof IoT devices and communication over insecure wireless channels. Therefore, this necessitates the design of an efficient security mechanism for IIoTenvironment. In this paper, we propose a hyperelliptic curve cryptography(HECC) based IIoT Certificateless Signcryption (IIoT-CS) scheme, with theaim of improving security while lowering computational and communicationoverhead in IIoT environment. HECC with 80-bit smaller key and parameterssizes offers similar security as elliptic curve cryptography (ECC) with 160-bitlong key and parameters sizes. We assessed the IIoT-CS scheme security byapplying formal and informal security evaluation techniques. We used Realor Random (RoR) model and the widely used automated validation of internet security protocols and applications (AVISPA) simulation tool for formalsecurity analysis and proved that the IIoT-CS scheme provides resistance tovarious attacks. Our proposed IIoT-CS scheme is relatively less expensivecompared to the current state-of-the-art in terms of computational cost andcommunication overhead. Furthermore, the IIoT-CS scheme is 31.25% and 51.31% more efficient in computational cost and communication overhead,respectively, compared to the most recent protocol.展开更多

Based on Ham's protocol, in this paper a new authenticated Diffie-Hellman key agreement protocol with half forward secrecy is proposed. This protocol is also based on a single cryptographic assumption, and is user authentication and shared key authentication. More importantly, our protocol provides forward secrecy with respect to one of the parties. For this reason, besides the advantages of Ham's protocol, in practice, our protocol can reduce the damages resulted from the disclosure of the user's secret key and it is very beneficial to today's communication with portable devices.展开更多

It highlights the Woo-Lam's ideas for authentication, which is the strongest one in Lowe's definition hierarchy for entity authentication. Apart from the flexible and natural features in forming and analyzing protocols inherited from ASM, the model defines both authentication and secrecy properties explicitly in first order sentences as invariants. The process of proving security properties with respect to an authentication protocol blends the correctness and secrecy properties together to avoid the potential flaws which may happen when treated separately. The security of revised Helsinki protocol is shown as a case study. The new model is different from the previous ones in ASMs.展开更多

Based on the efficient CPK scheme, we present an efficient three-round two-party authenticated key exchange protocol with strong security, which is provably secure in the standard model under the decisional Diffie-Hellman (DDH) assumption. The protocol can keep the session key secret from the adversary except that one party's ephemeral private key and static private key are all revealed to the adversary. Compared to the existing protocols, this protocol not only assures strong security but also is more efficient.展开更多

Meanwhile, the security problems based on Hash function RFID security authentication protocol in recent years have been also sorted and analyzed. Then a security model to design and analyze RFID protocols is built. By using the computational complexity, its correctness and security have been proved. Compared with the safety performance, storage overhead, computational overhead and other aspects of other protocols, the protocol for RFID has more efficient performance and ability to withstand various attacks. And the C# programming language is used to simulate the authentication process on the visual studio platform, which verifies the feasibility of the protocol.展开更多

The paper particularly focuses on automatic verification of authentication protocols. Our approach is based on the actual definitions of a protocol, not on some difficultto-establish justifications. The proposed methodology is different from many previous approaches to automatic verification of security protocols in that it is justification-oriented instead of falsification-oriented, i.e., finding bugs in a protocol. The main idea is based on observations: separating a principal executing a run of protocol from the role in the protocol, and inferring a principal's knowledge from the local observations of the principal. And we show analytically and empirically that this model can be easily reduced to Satisfiability (SAT) problem and efficiently implemented by a modern SAT solver.展开更多

Due to the unique identification number of the RFID tag, the possible privacy threats are information leakage of a tag, traceability of the consumer, denial of service attack, replay attack and impersonation of a tag, etc. There are a number of challenges in providing privacy and security in the RFID tag due to the limited computation, storage and communication ability of low-cost RFID tags. Many research works have already been conducted using hash functions and pseudorandom numbers. As the same random number can recur many times, the adversary can use the response derived from the same random number for replay attack and it can cause a break in location privacy. This paper proposes an RFID authentication protocol using a static identifier, a monotonically increasing timestamp, a tag side random number and a hash function to protect the RFID system from adversary attacks. The proposed protocol also indicates that it requires less storage and computation than previous existing RFID authentication protocols but offers a larger range of security protection. A simulation is also conducted to verify some of the privacy and security properties of the proposed protocol.展开更多

One of the most important applications is wireless medical sensor network (WMSN) , which makes modern heahh-care more popular. However, most of the sensor data transmitted in the WMSN is patient-related information. The sensor data are important and should be confidential. In addition, the attackers may also maliciously modify these sensor data. Therefore, both security and privacy are two very important issues in WMSN. A user authentication protocol and data security transmission mechanism based on bilinear pairing is proposed to protect data security and privacy. The proposed protocol enables the medical staff to monitor the health status of health care workers and provide timely and comprehensive health care information to the patient. Finally, through security and performance analysis, it can be found that the proposed authentication and key agreement protocol can resist common attacks such as impersonation attack, replay attack, online or offline password guessing attack, and stolen verifier attack. At the same time, this agreement is also in line with the performance of WMSN application environment.展开更多

文摘Forward secrecy is an important security property in key agreement protocol. Based on Ham's protocol, in this paper a new authenticated Diffie-Hellman key agreement protocol with half forward secrecy is proposed. This protocol is also based on a single cryptographic assumption, and is user authentication and shared key authentication. More importantly, our protocol provides forward secrecy with respect to one of the parties. For this reason, besides the advantages of Ham's protocol, in practice, our protocol can reduce the damages resulted from the disclosure of the user's secret key and it is very beneficial to today's communication with portable devices.

文摘A new semantic model in Abstract State Model (ASM) for authentication protocols is presented. It highlights the Woo-Lam's ideas for authentication, which is the strongest one in Lowe's definition hierarchy for entity authentication. Apart from the flexible and natural features in forming and analyzing protocols inherited from ASM, the model defines both authentication and secrecy properties explicitly in first order sentences as invariants. The process of proving security properties with respect to an authentication protocol blends the correctness and secrecy properties together to avoid the potential flaws which may happen when treated separately. The security of revised Helsinki protocol is shown as a case study. The new model is different from the previous ones in ASMs.

文摘Combined public key (CPK) cryptography does not need certificates to guarantee the authenticity of public keys and avoids the inherent key escrow problem of identity-based cryptography. Based on the efficient CPK scheme, we present an efficient three-round two-party authenticated key exchange protocol with strong security, which is provably secure in the standard model under the decisional Diffie-Hellman (DDH) assumption. The protocol can keep the session key secret from the adversary except that one party's ephemeral private key and static private key are all revealed to the adversary. Compared to the existing protocols, this protocol not only assures strong security but also is more efficient.

文摘Research on existing radio frequency identification(RFID) authentication protocols security risks, poor performance and other problems, a RFID security authentication protocol based on dynamic identification(ID) and Key value renewal is proposed. Meanwhile, the security problems based on Hash function RFID security authentication protocol in recent years have been also sorted and analyzed. Then a security model to design and analyze RFID protocols is built. By using the computational complexity, its correctness and security have been proved. Compared with the safety performance, storage overhead, computational overhead and other aspects of other protocols, the protocol for RFID has more efficient performance and ability to withstand various attacks. And the C# programming language is used to simulate the authentication process on the visual studio platform, which verifies the feasibility of the protocol.

文摘This paper introduces a new methodology for epistemic logic, to analyze communication protocols that uses knowledge structures, a specific form of Kripke semantics over hostile networks. The paper particularly focuses on automatic verification of authentication protocols. Our approach is based on the actual definitions of a protocol, not on some difficultto-establish justifications. The proposed methodology is different from many previous approaches to automatic verification of security protocols in that it is justification-oriented instead of falsification-oriented, i.e., finding bugs in a protocol. The main idea is based on observations: separating a principal executing a run of protocol from the role in the protocol, and inferring a principal's knowledge from the local observations of the principal. And we show analytically and empirically that this model can be easily reduced to Satisfiability (SAT) problem and efficiently implemented by a modern SAT solver.
文摘The use of radio frequency identification (RFID) tags may cause privacy violation of users carrying an RFID tag. Due to the unique identification number of the RFID tag, the possible privacy threats are information leakage of a tag, traceability of the consumer, denial of service attack, replay attack and impersonation of a tag, etc. There are a number of challenges in providing privacy and security in the RFID tag due to the limited computation, storage and communication ability of low-cost RFID tags. Many research works have already been conducted using hash functions and pseudorandom numbers. As the same random number can recur many times, the adversary can use the response derived from the same random number for replay attack and it can cause a break in location privacy. This paper proposes an RFID authentication protocol using a static identifier, a monotonically increasing timestamp, a tag side random number and a hash function to protect the RFID system from adversary attacks. The proposed protocol also indicates that it requires less storage and computation than previous existing RFID authentication protocols but offers a larger range of security protection. A simulation is also conducted to verify some of the privacy and security properties of the proposed protocol.

文摘With the development of wirdess network and electronic technologies, the wireless sensor network (WSN) has been widely used in many applications. One of the most important applications is wireless medical sensor network (WMSN) , which makes modern heahh-care more popular. However, most of the sensor data transmitted in the WMSN is patient-related information. The sensor data are important and should be confidential. In addition, the attackers may also maliciously modify these sensor data. Therefore, both security and privacy are two very important issues in WMSN. A user authentication protocol and data security transmission mechanism based on bilinear pairing is proposed to protect data security and privacy. The proposed protocol enables the medical staff to monitor the health status of health care workers and provide timely and comprehensive health care information to the patient. Finally, through security and performance analysis, it can be found that the proposed authentication and key agreement protocol can resist common attacks such as impersonation attack, replay attack, online or offline password guessing attack, and stolen verifier attack. At the same time, this agreement is also in line with the performance of WMSN application environment.

文摘With the continuous development of satellite communication and Internet of things technology,more and more devices can access space information networks(SIN)and enjoy satellite services everywhere in the world.However,due to the openness of the air-to-ground channel,the device will face a series of security threats when accessing SIN,such as replay attacks,eavesdropping attacks,impersonation attacks,and man-in-the-middle attacks.These security threats will lead to illegal entity access and further endanger the reliability and availability of the system.Although scholars have proposed many enhanced security access authentication protocols,most of them have been proved to have security vulnerabilities.In addition,with the development of quantum computing,the previous authentication protocols based on some asymmetric cryptographic mechanisms such as discrete logarithm and elliptic curve cryptographic mechanisms may face new security challenges.In this context,this paper proposes a novel antiquantum access authentication protocol based on ring learning with errors(RLWE),which meets more security requirements and greatly reduces the authentication delay through prenegotiation.Through the security analysis and performance analysis,it is shown that our protocol can be more suitable for delaysensitive IoT devices to access SIN while ensuring higher security.
