An ID-Based Authenticated Key Agreement Protocol for Peer-to-Peer Computing

Peer-to-peer computing has recently started to gain significant acceptance, since it can greatly increase the performance and reliability of overall system. However, the security issue is still a major gating factor for its full adoption. In order to guarantee the security of data exchanged between two peers in Peer-to-Peer system, this paper comes up with an ID-based authenticated key agreement from bilinear pairings and uses BAN logic to prove the protocol’s security. Compared with other existing protocols, the proposed protocol seems more secure and efficient, since it adopts the static shared Diffie-Hellman key.

ID-Based Authenticated Dynamic Group Key Agreement

Two ID-based authenticated group key agreement schemes, proposed by Choi et al and Du et al, are insecure against an impersonation attack and th ey only discussed the static group. This paper proposed a variant of BD protocol , which is fully authenticated by a proven-secure ID-based signature scheme. T he protocol can res ist the impersonation attack, and other security attributes are also satisfied. Compared with Choi et al and Du et al schemes, the proposed one is mor e efficient and applicable for dynamic groups.

Efficient Authenticated Key Agreement Protocol Using Self-Certified Public Keys from Pairings

An efficient authenticated key agreement protocol is proposed, which makesuse of bilinear pairings and self-certificd public keys. Its security is based on the securityassumptions of the bilinear Diff ie-Hellman problem and the computational Diffie-Hellman problem.Users can choose their private keys independently. The public keys and identities of users can beverified implicitly when the session key being generating in a logically single step. A trusted KeyGeneration Center is no longer requiredas in the ID-based authenticated key agreement protocolsCompared with existing authenticated key agreement protocols from pairings, the. new proposedprotocol is more efficient and secure.

An Efficient Lightweight Authentication and Key Agreement Protocol for Patient Privacy

Tele-medical information system provides an efficient and convenient way to connect patients at home with medical personnel in clinical centers.In this system,service providers consider user authentication as a critical requirement.To address this crucial requirement,various types of validation and key agreement protocols have been employed.The main problem with the two-way authentication of patients and medical servers is not built with thorough and comprehensive analysis that makes the protocol design yet has flaws.This paper analyzes carefully all aspects of security requirements including the perfect forward secrecy in order to develop an efficient and robust lightweight authentication and key agreement protocol.The secureness of the proposed protocol undergoes an informal analysis,whose findings show that different security features are provided,including perfect forward secrecy and a resistance to DoS attacks.Furthermore,it is simulated and formally analyzed using Scyther tool.Simulation results indicate the protocol’s robustness,both in perfect forward security and against various attacks.In addition,the proposed protocol was compared with those of other related protocols in term of time complexity and communication cost.The time complexity of the proposed protocol only involves time of performing a hash function Th,i.e.,:O(12Th).Average time required for executing the authentication is 0.006 seconds;with number of bit exchange is 704,both values are the lowest among the other protocols.The results of the comparison point to a superior performance by the proposed protocol.

Robust Authentication and Session Key Agreement Protocol for Satellite Communications

Satellite networks are recognized as the most essential communication infrastructures in the world today,which complement land networks and provide valuable services for their users.Extensive coverage and service stability of these networks have increased their popularity.Since eavesdropping and active intrusion in satellite communications are much easier than in terrestrial networks,securing satellite communications is vital.So far,several protocols have been proposed for authentication and key exchange of satellite communications,but none of them fullymeet the security requirements.In this paper,we examine one of these protocols and identify its security vulnerabilities.Moreover,we propose a robust and secure authentication and session key agreement protocol using the elliptic curve cryptography(ECC).We show that the proposed protocol meets common security requirements and is resistant to known security attacks.Moreover,we prove that the proposed scheme satisfies the security features using the Automated Validation of Internet Security Protocols and Applications(AVISPA)formal verification tool and On-the fly Model-Checker(OFMC)and ATtack SEarcher(ATSE)model checkers.We have also proved the security of the session key exchange of our protocol using theReal orRandom(RoR)model.Finally,the comparison of our scheme with similar methods shows its superiority.

Two Modifications on IKE Protocol with Pre-shared Key Authentication

This paper proposed two modifications on IKE protocol with pre-shared key authentication. The first modification can improve its immunity against DDoS attack by authenticating the initiator before the responder generates the computation-intensive Diffie-Hellman public value. The second modification can improve its efficiency when the attack on messages occurs because it can detect the attack quickly by replacing the centralized authentication in origical IKE protocol with immediate authentication. In addition, the two modifications can be integrated into one protocol compactly.

Two-party certificateless authenticated key agreement protocol with enhanced security

Two-party certificateless authenticated key agreement(CL-AKA) protocol is a hot topic in the field of wireless communication security. An improved two-party CL-AKA protocol with enhanced security is proposed,which is of provable security and unforgeability in the extended Canetti-Krawczyk(eCK) security model based on the hardness assumption of the computational Diffie Hellman(CDH) problem. Compared with other similar protocols, it is more efficient and can satisfy security properties such as free of the centralized management of certificate and key, free of bilinear pairings, two-party authentication, resistant to unknown key-share attack, key compromise impersonation attacks, the man-in-the-middle-attack(MIMA) of key generation center(KGC), etc. These properties make the proposed protocol have better performance and adaptability for military communication.

Authenticated Diffie-Hellman Key Agreement Protocol with Forward Secrecy

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.

Authentication in Wireless Body Area Network:Taxonomy and Open Challenges

Wearable body area network(WBAN)aids the communication between the health providers and patients by supporting health monitoring services.It assists the users to maintain their health status records by collecting the body signals and transmitting them for further processing measurements.However,sensor data are publicly transferred through insecure network that facilitates the attacker malicious acts like performing masquerading attack,man in the middle,and snooping.Several authentication techniques were suggested to levitate the security of the communication channels to preserve the user data from exposure.Moreover,authentication schemes aid plenty of security issues related to user and data privacy,anonymity,repudiation,confidentiality,and integrity,but they lack performance efficiency.On the other hand,it is very hard to find the balance between security and efficiency in most of the authentication schemes,especially for the WBAN platform that consists of memory and processing constraint devices.Therefore,this paper surveys and discusses the latest authentication schemes types,techniques,and system features.Also,it highlights their strengths and weaknesses towards common knowingly attacks and provides a comparison between the popular scheme validation proofs and simulation tools.Thence,this paper draws a path for the new direction of the authentication technologies,the authentication schemes open issues,and the potential future evolution in this area.
