New leakage-resilient CCA-secure public key encryption

open access: yesJournal of Mathematical Cryptology, 2013
This paper shows a generic method of constructing CCA-secure public key encryption schemes with leakage-resilience on the secret key. It is based on a new kind of universal2 hash proof system which accepts an auxiliary parameter.

An Efficient Conditional Privacy-Preserving Authentication Scheme for the Prevention of Side-Channel Attacks in Vehicular Ad Hoc Networks

open access: yesIEEE Access, 2020
Several group signature or identity schemes have been proposed for addressing the issues of security in a vehicular ad hoc network (VANET). Nonetheless, none of these schemes suitably cope with the performance efficient during the signing and verifying ...
