As the use of mobile devices continues to rise,trust administration will significantly improve security in routing the guaranteed quality of service(QoS)supply in Mobile Ad Hoc Networks(MANET)due to the mobility of the nodes.There is no continuance of network communication between nodes in a delay-tolerant network(DTN).DTN is designed to complete recurring connections between nodes.This approach proposes a dynamic source routing protocol(DSR)based on a feed-forward neural network(FFNN)and energybased random repetition trust calculation in DTN.If another node is looking for a node that swerved off of its path in this situation,routing will fail since it won’t recognize it.However,in the suggested strategy,nodes do not stray from their pathways for routing.It is only likely that the message will reach the destination node if the nodes encounter their destination or an appropriate transitional node on their default mobility route,based on their pattern of mobility.The EBRRTC-DTN algorithm(Energy based random repeat trust computation)is based on the time that has passed since nodes last encountered the destination node.Compared to other existing techniques,simulation results show that this process makes the best decision and expertly determines the best and most appropriate route to send messages to the destination node,which improves routing performance,increases the number of delivered messages,and decreases delivery delay.Therefore,the suggested method is better at providing better QoS(Quality of Service)and increasing network lifetime,tolerating network system latency. 展开更多

How to build a secure architecture for network function virtualization(NFV)is an important issue.Trusted computing has the ability to provide security for NFV and it is called trusted NFV system.In this paper,we propose a new NFV direct anonymous attestation(NFV-DAA)scheme based on trusted NFV architecture.It is based on the Elliptic curve cryptography and transfers the computation of variable D from the trusted platform module(TPM)to the issuer.With the mutual authentication mechanism that those existing DAA schemes do not have and an efficient batch proof and verification scheme,the performance of trusted NFV system is optimized.The proposed NFV-DAA scheme was proved to have a higher security level and higher efficiency than those existing DAA schemes.We have reduced the computation load in Join protocol from 3G_1to 2G_1 exponential operation,while the time of NFV-DAA scheme's Sign protocol is reduced up to 49%. 展开更多

Goud computing is a new paradigm in which dynamic and virtualized computing resources are provided as services over the Internet. However, because cloud resource is open and dynamically configured, resource allocation and scheduling are extremely important challenges in cloud infrastructure. Based on distributed agents, this paper presents trusted data acquisition mechanism for efficient scheduling cloud resources to satisfy various user requests. Our mechanism defines, collects and analyzes multiple key trust targets of cloud service resources based on historical information of servers in a cloud data center. As a result, using our trust computing mechanism, cloud providers can utilize their resources efficiently and also provide highly trusted resources and services to many users. 展开更多

In this paper, a formal approach based on predicate logic is proposed for representing and reasoning of trusted computing models. Predicates are defined to represent the characteristics of the objects and the relationship among these objects in a trusted system according to trusted computing specifications. Inference rules of trusted relation are given too. With the semantics proposed, some trusted computing models are formalized and verified, which shows that Predicate calculus logic provides a general and effective method for modeling and reasoning trusted computing systems. 展开更多

In order to solve the issue that existing direct anonymous attestation (DAA) scheme can not operate effectively in different domains,based on the original DAA scheme,a novel direct anonymous attestation protocol used in multi domains environment is proposed and designed,in which,the certificate issuer located in outside of domain can be considered as a proxy server to issue the DAA certificate for valid member nodes directly.Our designed mechanism accords with present trusted computing group (TCG) international specification,and can solve the problems of practical authentication and privacy information protection between different trusted domains efficiently.Compared with present DAA scheme,in our protocol,the anonymity,unforgeability can be guaranteed,and the replay-attack also can be avoided.It has important referenced and practical application value in trusted computing field. 展开更多

Current delegation mechanism of grid security infrastructure (GSI) can't satisfy the requirement of dynamic, distributed and practical security in grid virtual organization. To improve this situation, a TC-enabled GSI is discussed in this paper. With TC-enabled GSI, a practical delegation solution is proposed in this paper through enforcing fine granularity policy over distributed platforms with the emerging trusted computing technologies. Here trusted platform module is treated as a tamper-resistance module to improve grid security infrastructure. With the implement of Project Daonity, it is demonstrated that the solution could gain dynamic and distributed security in grid environment. 展开更多

Trusted computing (TC) technology is brought out by trusted computing group (TCG) to make computing as safe and reliable as people expect. Attestation is one main function specified by TCG, which is the means by which a trusted computer assures a remote computer whose platform is not tampered with. There are two protocols that implement attestation without disclosing the platform's real identity, which are Privacy CA-based protocol and direct anonymous attestation (DAA) protocol. However, in the first protocol the privacy CA is the bottleneck and the platform's identity will be disclosed if the privacy CA is compromise, while DAA protocol can do profiling when dealing with rogue hardware device. In this paper, we propose a DAA-extended new approach to ensure full anonymous attestation that can not only detect a rogue TPM, but also reveal rogue TPM's real identity. 展开更多

Since the guarantee of trustiness is considered inadequate in traditional software development methods,software developed using these methods lacks effective measures for ensuring its trustiness.Combining agent technique with the support of trusted computing provided by TPM,a trust-shell-based constitution model of trusted software(TSCMTS)is demonstrated,trust shell ensures the trustiness of software logically.The concept of Trust Engine is proposed,which extends the "chain of trust" of TCG into application,and cooperates with TPM to perform integrity measurement for software entity to ensure the static trustiness;Data Structure called trust view is defined to represent the characteristic of software behavior.For the purpose of improving the accuracy of trustiness constraints,a strategy for determining the weights of characteristic attributes based on information entropy is proposed.Simulation experiments illustrate that the trustiness of software developed by the TSCMTS is improved effectively without performance degradation. 展开更多

Facing the increasing security issues in P2P networks, a scheme for resource sharing using trusted computing technologies is proposed in this paper. We advance a RS-UCON model with decision continuity and attribute mutability to control the usage process and an architecture to illustrate how TC technologies support policy enforcement with bidirectional attestation. The properties required for attestation should include not only integrity measurement value of platform and related application, but also reputation of users and access history, in order to avoid the limitation of the existing approaches. To make a permission, it is required to evaluate both the authorization and conditions of the subject and the object in resource usage to ensure trustable resources to be transferred to trusted users and platform. 展开更多

Putting together the VMM architecture, TCG hardware and application-oriented "thin" virtual machine (VM), Trusted VMM-based security architecture is present in this paper with the character of reduced and distributed trusted computing base (TCB).

The Trusted Platform Module (TPM) is a dedicated hardware chip designed to provide a higher level of security for computing platform. All TPM functionalities are implemented in TPM corntrends to achieve specific security goals. We attempt to analyze the security properties of these commands, especially the key management API. Our study utilizes applied pi calculus to forrmlize the commands and determine how their security properties affect TPM key rmnagement. The attacker is assumed to call TPM comrmnds without bounds and without knowing the TPM root key, expecting to obtain or replace the user key. The analysis goal in our study is to guarantee the corre- sponding property of API execution and the integrity of API data. We analyze the security properties of TPM commands with a process reduction method, identify the key-handle hijack attack on a TPM newly created key, and propose reasonable solutions to solve the problem. Then, we conduct an experiment involving a key-handle attack, which suc- cessfully replaces a user key with an attacker's key using lmlicious TPM software. This paper discloses the weakness of the relationship between the key handle and the key object. After the TPM software stack is compromised, the attacker can hunch a keyhandle attack to obtain the user key and even break into the whole storage tree of user keys. 展开更多

Trust is one of the most important security requirements in the design and implementation of peer-to-peer (P2P) systems. In an environment where peers' identity privacy is important, it may conflict with trustworthiness that is based on the knowledge related to the peer's identity, while identity privacy is usually achieved by hiding such knowledge. A trust model based on trusted computing (TC) technology was proposed to enhance the identity privacy of peers during the trustworthiness evaluation process between peers from different groups. The simulation results show that, the model can be implemented in an efficient way, and when the degree of anonymity within group (DAWG) is up to 0.6 and the percentage of malicious peers is up to 70%7 the service selection failure rate is less than 0.15. 展开更多

It is absolutely critical that trusted configuration management which significantly affects trust chain establishment, sealing storage and remote attestation, especially in trusted virtualization platform like Xen whose system configuration changes easily. TPM (trusted platform module) context manager is presented to carry out dynamic configuration management for virtual machine. It manages the TPM command requests and VM (virtual machine) configurations. The dynamic configuration representa- tion method based on Merkle hash tree is explicitly proposed against TCG (trusted computing group) static configuration representation. It reflects the true VM status in real time even if the configuration has changed, and it eliminates the invalidation of configuration representation, sealing storage and remote attestation. TPM context manager supports TCG storage protection, remote attestation etc, which greatly enhances the security on trusted virtualization platform. 展开更多
