Research of platform identity attestation based on trusted chip by Qian-ying ZHANG, Deng-guo FENG, Shi-jun ZHAO

“…Compared to other schemes, this scheme not only has much lower calculation and communication, but also convinces the verifier of the trustworthiness of the client's platform state during the platform identity attestation. A detailed security proof of the proposed scheme is presented by using the protocol composition logic, and the proof shows that the scheme satisfies correctness and anonymity of platform identity verification. …”

5-pass zero-knowledge identity authentication scheme based on matrix completion problem by Houzhen WANG, Xinwei CAI, Yan GUO, Huanguo ZHANG

“…To solve the problem that most identity authentication schemes are vulnerable to quantum-computing attacks and low efficiency, a new 5-pass zero-knowledge identity authentication scheme was designed based on the matrix completion problem (MCP).Since the MCP is NP-complete, the proposed scheme has the potential to avoid quantum-computing attacks.Compared with the existing similar protocols, the proposed scheme reduced the fraud probability from 2/3 to 1/2 by adding a single round of interaction, and had the advantages of easy implementation and small key size.Moreover, based on the proposed zero-knowledge authentication scheme and Fiat-Shamir standard transformation method, a secure and efficient digital signature algorithm against quantum-computing can be obtained.…”

Watermarking algorithm for image authentication based on second generation Bandelet by LIU Xu-chong1, LUO Yong1, WANG Jian-xin1, WANG Jie1

“…A watermarking algorithm for image authentication was designed,which was based on second generation Bandelet translation and statistical model.The image directional flow was constructed by using Bandelet,and it could depict the characteristic of the image.By applying noise visibility function,the noise visibility intensity algorithm which was based on Gaussian statistical models was proposed.The blocks of image which contain more texture information were selected to hide the image directional flow,based on the noise visibility intensity algorithm.The image was authen-ticated through comparing the hiding information and the carrier image directional flow created by Bandelet.Experimen-tal results show that the algorithm can resist the JPEG compression and noise attack strongly and guarantee the quality of the sight.It is a blind detection algorithm,and this algorithm has high concealment performance and security.…”

Detecting and preventing collusion attack in DPoS based on power index by Xiaodong FU, Xinxin QI, Li LIU, Wei PENG, Jiaman DING, Fei DAI

“…Since malicious nodes may manipulate voting elections through collusion attacks in consensus mechanism of DPoS, the security of block chain can not be guaranteed in the consensus process of DPoS.To deal with the problem, a method for detecting and preventing collusion attack in DPoS based on power index was proposed.Firstly, a weighted voting game model of DPoS was constructed based on the idea of power index in game theory, and the behavioral motivation of the malicious node could be analyzed.Then, the attacks were detected based on changing range of abnormal power index.During the process of preventing collusion attacks in DPoS, the Softsign activation function was adapted to suppress the power index of malicious nodes.Lastly, the effectiveness of the proposed method to detect and prevent collusion attacks in DPoS was verified through theoretical analysis and experiments.…”

Research on sybil attack in defense blockchain based on improved PBFT algorithm by Yingxu LAI, Zunxu BO, Jing LIU

“…Aiming at the problem that sybil attack has great harm to block chain technology,a method to improve the PBFT algorithm in the alliance chain to defend against sybil attacks was proposed.Firstly,using the idea of consensus algorithm based on proof of rights and interests,a reputation model was established,the reputation value of each node accorded to the behavior of each node in the consensus process was calculated,and different discourse rights accorded to the size of the reputation value was given.Then pre-commit phase was added to the PBFT algorithm to reduce the number of communication between nodes.The solution through formal analysis and reasoning and security testing shows that the improved PBFT algorithm can not only effectively defend against sybil attacks in the blockchain,but also make the performance of the blockchain system in terms of TPS and block generation delay.…”

Proxy re-signature scheme based on isomorphisms of polynomial by Hui-xian LI, Lu SHAO, Liao-jun PANG

“…Most of the existing proxy resignature schemes were based on the hardness of big integer factoring,discrete logarithm,elliptic curve.However,none of them can resist the attack by a quantum computer.Motivated by these concerns,a new proxy resignature scheme was proposed.By employing secret affine transformations and homogeneous polynomials,the proposed scheme could implement the signature transformation with high-efficiency,and meanwhile it was secure against the attack by a quantum computer.The results of analysis showed that the proposed scheme was correct and consistent,and had the unforgeability in the random oracle model.Compared with the existing schemes,the proposed scheme not only inherits the resistance to quantum attack and high efficiency from the multivariate public key cryptosystems,but also has the properties of multi-use,transparent and private proxy.…”
