In 2004, Choi et al. proposed an ID-based authenticated group key agreement. Unfortunately, their protocol was found to be vulnerable the insider attacks by Zhang, Chen and Shim. To prevent attacks, Shim presented a modification of al.'s protocol. this letter, we first show that Shim's is still insecure against attacks. We then present resists The counter-measure uses signature on transcripts in order bind them session. This prevents any replay transcripts. Especially, applying batch...
Chou suggested a constant-time implementation for quasi-cyclic moderatedensity parity-check (QC-MDPC) code-based cryptography to mitigate timing attacks at CHES 2016. This countermeasure was later found become vulnerable differential power analysis (DPA) in private syndrome computation, as described by Rossi et al. 2017. The proposed DPA, however, still could not completely recover accurate secret indices, requiring further solving linear equations obtain entire information. In this paper,...

The goal of VANETs is to develop an efficient and se- cure communication system applicable vehicles en- hance driver's safety comfort. Since information flow- ing through inherently life-critical sensi- tive location privacy, vehicular communications should provide anonymity authenticity without sacrificing effi- ciency. This makes it difficult design a secure communi- cation scheme for VANETs. In this paper, we propose the signature which resolve key update problem in using tamper-proof...
