CCA-secure verifiable Mix-Net protocol by Long-hai LI, Cheng-qiang HUANG, Shang-mei XU, Shao-feng FU

“…A CCA-secure verifiable Mix-Net protocol with provable security was proposed.The protocol was based on Wikström’s Mix-Net and improves its security by introducing an improved key generation algorithm and a new method for constructing proof of secret shuffling.Without revealing the correspondence between inputs and outputs,proposed protocol enables everyone to verify the correctness of output plaintexts through checking evidences broadcasted by each server.Thus,it satisfies public verifiability.Any sender can trace and examine the processing procedure of its ciphertext.Thus,proposed protocol satisfies sender verifiability.It is prored to be CCA-secure under the assumption of random oracle.Compared with previous mix-net schemes which are CCA-secure,proposed protocol does not require any trusted center,and incurs fewer interactions between servers which also resulting in a lower computation and communication complexity.Hence,the protocol is an ideal cryptographic tool for constructing secure electronic election protocol.…”

WSN key recovery attack based on symmetric matrix decomposition by Xiangmin JI, Bo ZHAO, Jinhui LIU, Jianwei JIA, Huanguo ZHANG, Shuang XIANG

“…The key protocol is one of the crucial technologies to ensure the security for wireless sensor network（WSN）.Parakh,et al.proposed a key agreement for WSN based on matrix decomposition.However,the study revealed that the protocol had security risks.A key recovery attack scheme against this protocol was proposed by using the properties of symmetric matrix and permutation matrix.Based on intercepting the row and column vector of the node,elementary transformation was performed to construct a linear algebraic attack algorithm and the equivalent key was obtained.The computational complexity is O(N<sup>6</sup>).Experimental results show that the method can recover the equivalent key of the above protocol within the polynomial computational complexity and the memory consumption is within an acceptable range.In addition,an improved scheme for key agreement was proposed to resist the linear algebraic attack by using a random disturbance matrix,and the correctness and security analysis were also carried out.…”

Security analysis of weighted network anonymity based on singular value decomposition by Yong ZENG, Lingjie ZHOU, Zhongyuan JIANG, Zhihong LIU, Jianfeng MA

“…The security of anonymous method based on singular value decomposition (SVD) in the privacy preserving of weighted social network was analyzed.The reconstruction method in network with integer weights and the inexact reconstruction method in network with arbitrary weighted were proposed.The <inline-formula><math xmlns="http://www.w3.org/1998/Math/MathML"> <mfrac> <mi>ε</mi> <mi>N</mi> </mfrac> </math></inline-formula> -tolerance was definited to measure its safety.It was also pointed out that the upper bound of ε (the reconfigurable coefficient) obtained in current spectral theories was so conservative that lacks of guidance.The reconfigurable coefficients of random networks,Barabasi-Albert networks,small world networks and real networks were calculated by experiment.Moreover,the reconfigurable coefficients of double perturbation strategies based on SVD were also tested.Experimental results show that weighted social networks have different tolerances on spectrum loss,and there is a close relationship between its tolerance and network parameters.…”
