A video encryption in HEVC entropy coding based on magic square by Bowen XU, Xiaodong WANG, Lei GUO, Jian WANG

“…In view of the multimedia information security,based on the entropy module on high efficiency video coding (HEVC/H.265),combined with the magic square,a real time and high efficiency encryption technique for high-definition video streaming was proposed.The algorithm which had an effective use of transform coefficient sparsity enabled coefficient group (CG) of transform block (TB) scrambling,and used a selective encryption on syntax elements in CG's entropy.The experiments prove that the investigated scheme has high security,which can guarantee the standard compliance and the demand of video encryption while having a low impact on encoding-rate performance.…”

Analysis and improvement of an identity-based signature scheme from lattices by ANGChun-li Y, ANJian-hua Y, HENGShi-hui Z, ANGLi-cheng W, ANGYu Y

“…Liu et al proposed an identity-based signature from lattices in 2013,and proved that it can achieve strong un-forgeability in the standard model.Through analysis,the security proof of this scheme has some defect,and then show that the scheme cannot prove the strong unforgeability under selective identity and adaptive chosen-message attacks.Then,using Boyen signing technique (PKC 2010) inpoves the signing algorithm,and proves the strong unforgeability under selective identity and adaptive chosen-message attacks (SU-sID-CMA) in the standard model.In addition,it com-pares the efficiency and security of the scheme and the other identity-based signatures from lattices.…”

ID-based efficient and proactive threshold proxy signature in the standard model by YU Yi-ke1, ZHENG Xue-feng2

“…The security of existing identity-based threshold proxy signature schemes were almost proven in the random oracle model,and each proxy signer’s proxy signature key was fixed in the valid period.A（t,n） ID-based proactive threshold proxy signature scheme（IBTPTS） was presented by using the publicly verifiable secret sharing technology,based on existential identity-based signature scheme.The scheme was proved to be safe in the standard model.Each proxy signer’s proxy signature key can be updated regularly,and proxy signature verifying procedure only needs const bi-linear pairings.Therefore the scheme has better dynamic security and higher efficiency.…”

Tag's ownership transfer protocol based on quadratic residue by Rui XIE, Zhifeng HAO

“…A proprietary transfer protocol with higher security and lower cost was proposed.In order to ensure the communication entity authentication premise,two remainder theorems for information transmission encryption were used in the proposed protocol; in the process of mutual recognition of communication entities,the addition of random numbers could make the protocol effectively resist such attacks as replay and desynchronization.After the transfer of ownership occurs,new communication entities would be located.The authentication key needed to be dynamical,so as to reduce the storage space of communication entities.The performance comparison between the proposed protocol and other protocols for safety show that the proposed protocol has the security required for the transfer of ownership and low cost.…”

Host’s source address verification based on stream authentication in the IPv6 access subnet by Yue CHEN, Hong-yong JIA, Peng-xu TAN, Jing SHAO

“…A cryptographically-implemented high-speed source address verification scheme for the hosts in the IPv6 access subnet was proposed.The MAC address was used as the identity of the host machine and bounded with the host’s public key.Then the IPv6 address was derived from the host machine’s public key using the cryptographically generated address algorithm.The address authenticity was guaranteed by the digital signature and the fast and secure source address verification for packet stream was achieved through message authentication code algorithm and stream authentication.The experimental system show that the scheme could ver fy the source addresses of data packets at a loss cost.Thus,it is a secure and feasible scheme.…”

Dynamic multi-keyword searchable encryption scheme by Chenghao YUAN, Yong LI, Shuang REN

“…Users of cloud storage often outsource their data to cloud servers to save local storage resources.However, cloud storage data is out of the user’s physical control, which may lead to malicious theft or disclosure of private data on cloud.At present, dynamic searchable encryption schemes are mostly based on symmetric searchable encryption, which need to establish a secure key sharing channel in advance, and cannot be directly applied to data sharing in cloud storage scenarios.For the secure sharing scenario of multi-party data in cloud storage, a dynamic multi-keyword searchable encryption scheme was proposed.The forward index was constructed by a cuckoo filter to enable data owners to perform documents and index dynamic updates.The conjunctive multi-keywords search was supported by combining bilinear pairing with Lagrangian interpolation polynomials.To reduce the computational overhead in the ciphertext retrieval phase, a combination of inverted index and forward index was constructed to improve the retrieval efficiency of cloud server.This scheme is provably secure with the indistinguishability in adaptively chosen keyword attack under decision linear Diffie-Hellman problem.Simulation experiments were conducted to analyze the execution efficiency of the scheme for keyword search and index update in different datasets.The results show that the scheme effectively avoids the linear correlation between the retrieval time and the number of ciphertexts, and reduces the computational overhead in the update operation with a large amount of data.…”

Research on mimic decision method based on deep learning by Xiaohan YANG, Guozhen CHENG, Wenyan LIU, Shuai ZHANG, Bing HAO

“…Due to software and hardware differentiation, the problem of false positives mistakenly identified as network attack behavior caused by inconsistent mimic decision results frequently occurs.Therefore, a mimic decision method based on deep learning was proposed.By constructing an unsupervised autoencoder-decoder deep learning model, the deep semantic features of diverse normal response data were explored from different executions and its statistical rules were analyzed and summarized.Additionally, the offline learning-online decision-making mechanism and the feedback optimization mechanism were designed to solve false positive problem, thereby accurately detecting network attacks and improving target system security resilience.Since statistical rules of normal response data was understood and mastered by deep learning model, the mimic decision results among different executions could remain consistent, indicating that the target system was in a secure state.However, once the target system was subjected to a network attacks, the response data outputted by the different executions was deviated from statistical distribution of deep learning model.Therefore, inconsistent mimic decision results were presented, indicating that the affected execution was under attack and the target system was exposed to potential security threats.The experiments show that the performance of the proposed method is significantly superior to the popular mimic decision methods, and the average prediction accuracy is improved by 14.89%, which is conducive to integrating the method into the mimic transformation of real application to enhance the system’s defensive capability.…”
