Block cipher based on T-shaped cellular automata by WU Ying-zhi1, HAO Li-bo2, CHEN Ju-hua1

“…In order to overcome the defect on insecurity of block cipher with few reversible cellular automata, T-shaped cellular automata was proposed, which needed two initial states and applied their characteristics to construct more re-versible cellular automata.A new encryption system based on this class of self-reversible cellular automata was designed.Experiments show that block cipher based on reversible cellular automata not only achieves a better avalanche effect but also improves the security of the applications of cellular automata in cryptography, especially by using pseudo random sequences in the beginning of encryption.…”

Co-decode algorithm of network coding with hardware logic by Hui LI, Ming-long ZHANG, Fu-xing CHEN, Han-xu HOU, Kai PAN, Wei WANG, Hu-sheng YUAN, Tao SUN

“…Practical general coder and decoder of network coding(NC)with HDL(hardware description language)logic for wire-speed nodes was presented.The NC coders applied random linear network coding (RLNC) and the decoders recovered the original packets by Cramer’s rule.The structures and algorithms of NC coder and decoder were designed in detail and implemented in HDL with NetFPGA boards.Comparing with traditional stored-and-forward mechanism,network emulations showed that networks with wire-speed NC coder and decoder nodes could achieve the capacity bound of max-flow min-cut theorem,and the end-to-end delay was guaranteed on a small constant.…”

Global External Stochastic Stabilization of Linear Systems with Input Saturation: An Alternative Approach by Qingling Wang

“…This paper presents results concerning the global external stochastic stabilization for linear systems with input saturation and stochastic external disturbances under random Gaussian distributed initial conditions. The objective is to construct a class of control laws that achieve global asymptotic stability in the absence of disturbances, while guaranteeing a bounded variance of the state for all the time in the presence of disturbances. …”

Multi-authority attribute-based encryption with efficient revocation by Kai ZHANG, Jian-feng MA, Hui LI, Jun-wei ZHANG, Tao ZHANG

“…Multi-authority attribute-based encryption was very suitable for data access control in a cloud storage environment.However,efficient user revocation in multi-authority attribute-based encryption remains a challenging problem that prevents it from practical applications.A multi-authority ciphertext-policy attribute-based encryption scheme with efficient revocation was proposed in prime order bilinear groups,and was further proved statically secure and revocable in the random oracle model.Extensive efficiency analysis results indicate that the proposed scheme significantly reduce the computation cost for the users.In addition,the proposed scheme supports large universe and any monotone access structures,which makes it more flexible for practical applications.…”

Enhanced-AAWP,a heterogeneous network oriented worm propagation model by LIU Bo, WANG Huai-min, XIAO Feng-tao, CHEN Xin

“…A logical worm propagation model contributes to the analysis of how exactly various worms spread in Internet.With the abstract of heterogeneous network environments,and considering the impact of infection time on worm propa-gation,a heterogeneous network oriented worm propagation model namely Enhanced-AAWP was derived using discrete time and deterministic approximation.Then,the worms which employed local preference scanning or random scanning were studied based on Enhanced-AAWP.As the simulation results show,the amount of NAT,the density of vulnerable hosts in NATs,and the probability of local preference scanning are influencing factors during the course of worm propa-gations in heterogeneous network environments.…”

5G millimeter wave UE test method and analysis by Jian GONG, Yu ZHANG

“…In the 5G millimeter wave UE OTA RF conformance test, EIRP and TRP type of tests are important OTA items.Currently, this method relying on 3GPP-defined random scan to lock the beam to determine the maximum EIRP and TRP, but this method is time-consuming and lacks accuracy.A non-signaling test method was proposed, which could not only achieve more accurate measurements compared with the current EIRP and TRP test methods but also make it possible to use the non-directional OTA site as the measurement environment, further reducing the test cost and time cost, and increasing the flexibility of the test environment selection.…”

Secure communication mechanism for VSN based on certificateless signcryption by Wenbo ZHANG, Wenhua HUANG, Jingyu FENG

“…To solve the communication security problems of vehicular social network (VSN), an efficient certificateless signcryption scheme was proposed.The proposed scheme was proven secure in the random oracle model based on the computational Diffie-Hellman problem and elliptic curve discrete logarithm problem, which provided confidentiality and unforgeability protection for VSN members.In addition, when the pseudonym mechanism was used to solve the privacy protection problem in VSN, without installing tamper-proof device, a self-generation mechanism for vehicle pseudonyms and their keys was proposed.The performance analysis shows that the proposed scheme can decrease communication cost, and significantly reduce the computation overhead of the key generation center.…”
