Attribute-based proxy re-encryption scheme with multiple features by Chaosheng FENG, Wangping LUO, Zhiguang QIN, Ding YUAN, Liping ZOU

“…A ideal proxy re-encryption scheme has five features,such as one-way encryption,non-interaction,repeatability,controllability and verifiability.The existing schemes,however,have only two or three of the five features,which reduces the utility of them to some extent.For this,a new ciphertext-policy attribute-based proxy re-encryption (CP-ABPRE) scheme with the above five features was proposed.In the proposed scheme,the cloud proxy server could only re-encrypt the ciphertext specified by the delegator by using the re-encryption key,and resist the collusion attack between the user and the proxy satisfying the re-encryption sharing policy.Most of encryption and decryption were outsourced to cloud servers so that it reduced the computing burden on the user’s client.The security analysis show that the proposed scheme resists the selective chosen plaintext attack (SCPA).…”

Dependable identity recognition and authorization based on visual information by Chunlei PENG, Xinbo GAO, Nannan WANG, Jie LI

“…Recently,deep learning has been widely applied to video and image based identity recognition and authorization tasks,including face recognition and person identification.However,machine learning models,especially deep learning models,can be easily fooled by adversarial attacks,which may cause the identity recognition systems to make a wrong decision.Therefore,dependable identity recognition and authorization has become one of the hot topics currently.Recent advances on dependable identity recognition and authorization from both information space and physical space were presented,where the development of the attack models on face detection,face recognition,person re-identification,and face anti-spoofing as well as printable adversarial patches were introduced.The algorithms of visual identity anonymization and privacy protection were further discussed.Finally,the datasets,experimental protocols and performance of dependable identity recognition methods were summarized,and the possible directions in the future research were presented.…”

Improving replicator dynamic evolutionary game model for selecting optimal defense strategies by Jianming HUANG, Hengwei ZHANG

“…In terms of the existence of strategy dependency in the same game group,network attack-defense evolutionary game model based on the improved replicator dynamics was constricted by introducing the intensity coefficient,which completed the method of calculating replicator dynamic rate.The improved replicator dynamic equation was adopted to solve the evolutionary equilibrium for the situation that both attack and defense have two optional strategies.The stability of the equilibrium points was analyzed by the local stability analysis method of Jacobian matrix,and the optimal defense strategies were obtained under different conditions.The results show that the strategy dependency between the players in the same group has a certain influence on the evolution of the game,both the incentive and the inhibition.Finally,the accuracy and validity of the model and method are verified by the experimental simulation,which provides a new theoretical support for solving the information security problems in the real.…”

Research on security architecture of strong PUF by adversarial learning by Yan LI, Wei LIU, Yuanlu SUN

“…To overcome the vulnerability of strong physical unclonable function, the adversarial learning model of strong PUF was presented based on the adversarial learning theory, then the training process of gradient descent algorithm was analyzed under the framework of the model, the potential relationship between the delay vector weight and the prediction accuracy was clarified, and an adversarial sample generation strategy was designed based on the delay vector weight.Compared with traditional strategies, the prediction accuracy of logistic regression under new strategy was reduced by 5.4% ~ 9.5%, down to 51.4%.The physical structure with low overhead was designed corresponding to the new strategy, which then strengthened by symmetrical design and complex strategy to form a new PUF architecture called ALPUF.ALPUF not only decrease the prediction accuracy of machine learning to the level of random prediction, but also resist hybrid attack and brute force attack.Compared with other PUF security structures, ALPUF has advantages in overhead and security.…”

Fingerprint template protection by adopting random projection based on re-encryption by Shan JIA, Zhengquan XU, Chuanbo HU, Hao WANG

“…In random projection (RP) based biometric template protection methods,the generated template and key are vulnerable to attacks,which may cause the leakage of users’ privacy.To solve this problem,an improved RP-based fingerprint template protection method was proposed.First,based on the RP result,the proposed method divided the projection domain into fingerprint matching domain and noise adding domain that were mutually independent,then fused them with two sub-matrices of the random projection matrix and saved the result as template.In addition,re-encryption mechanism was introduced to realize secure storage and transmission of the key (RP matrix).Experimental results show that the proposed method can achieve stronger ability to resist different attacks than existing RP-based biometric template protection methods,and also guarantee high matching accuracy and revocation.…”

Optimum response scheme of intrusion detection based on information theory by Youliang TIAN, Yulong WU, Qiuxian LI

“…Intrusion detection system (IDS) often inevitably presents major security risks caused by FPs and FNs.However,at present,an effective solution has not been found.In order to solve this problem,an optimal response model of intrusion detection based on information theory was proposed.Firstly,the intruder and IDS in the process of intrusion detection were abstracted into random variables,and the attack and defense model of intruder and IDS was constructed according to the results of the confrontation.Secondly,the defense channel of IDS was designed according to the attack and defense model,then the correct detection of IDS was transformed into the problem of successful transmission of 1 bit information in defensive channel.Finally,the defensive capability of the system was measured by analyzing the channel capacity of the defensive channel,the maximum mutual information of the defensive channel was the defensive limit capability of the IDS,and the corresponding strategy distribution was the optimal response strategy of the defensive capability of the system.The experimental results show that the scheme can effectively reduce the loss caused by FPs and FNs.…”

Triple receiver public key encryption cryptosystem by Liutao ZHAO, Lin ZHONG, Jidong LIU, Caiqun WANG, Dan WU

“…A triple receiver public key cryptosystem was proposed.In the cryptosystem,a sender encrypted a message and sent to three receivers,while the three receivers were able to decrypt the message with their own private keys.Based on bilinear map,two triple receiver public key encryption schemes with different security were constructed.If the gap bilinear Diffie-Hellman (GBDH) problem and the computational Diffie-Hellman (CDH) problem were proved formally to be intractable,then the two schemes proposed were semantically secure against chosen-plaintext attacks and against adaptive chosen ciphertext attacks respectively.The proposed scheme only added an exponential operation and a hash operation,and constructed three independent receivers which had a high efficiency.Analyses show that proposed scheme can improve the security of TLS protocol and apply to hierarchical public key cryptosystems.…”

Multi-server identity authentication scheme based on biometric and chaotic maps by Jianwu ZHANG, Zejin YAO, Zhendong WU

“…Password-based user remote authentication system has been widely used in recent years,the study found that a single password system is so vulnerable to dictionary analysis and brute force attack as well as other attacks that the security is not high.Biometric and password combination authentication method gradually added to the remote authentication system in order to improve the security level of authentication system.However,the existing authentication systems work in a single server environment,if extended to a multi-server environment,biometric templates and passwords will encounter single point breakthrough and cross-crack problem.In order to overcome the above problems,a multi-server key authentication scheme based on biometric and chaotic map was proposed.The scheme was based on smart cards,passwords and biometrics,which could significantly improve the security and the ability of anti-password guessing of multi-server authentication systems.…”
