New chameleon Hashing of secure and privacy-preserving vehicular communications
Published 2014-11-01“…Many services and applications in vehicular ad-hoc networks (VANET) require preserving and secure data communications.To improve driving safety and comfort,the traffic-related status information will be broadcasted regularly and shared among drivers.Without the security and privacy guarantee,attackers could track their interested vehicles by collecting and analyzing their traffic messages.Hence,anonymous message authentication is an essential requirement of VANET.On the other hand,when a vehicle is involved in a dispute event of warning message,the certificate authority should be able to recover the real identity of this vehicle.To deal with this issue,Guo,et al proposed a new privacy-preserving authentication protocol with authority traceability using elliptic curve based chameleon Hashing.Although this scheme has vehicle identification traceability and high computational efficiency than the previous plan,but analysis shows that the scheme does not meet the anonymity.The security of Guo's scheme is analyzed and improvement is made based on Guo’s protocol.…”

Attacking scheme against the permutation-based multi-polynomial scheme for pair-wise key establishment in wireless sensor networks
Published 2015-08-01“…An attacking scheme was proposed against the permutation-based multi-polynomial scheme proposed by Guo,et al for pair-wise key establishment in wireless sensor networks.Attacks on polynomials were carried out by constructing a black-box to integrally solve the set of polynomials rather than a single polynomial.The results show that this scheme can break the symmetric polynomials and make the permutation of polynomials lose its function.The proven theorems and instance analysis indicate that the scheme proposed by Guo,et al can’t frustrate the large-scale node capture attack and can’t break the tolerance threshold of polynomials.Therefore,the scheme is insecure.…”
