Aggregation schemes allow to combine several cryptographic values like message authentication codes or signatures into a shorter value such that, despite compression, some notion o...
In this paper we proposed a video signature based on ordinal measure of resampled video frames, which is robust to changing compression formats, compression ratios, frame sizes an...
Digital Signature Algorithm (DSA) is an underlying algorithm to form a signature in the Digital Signature Standard (DSS). DSA uses a new random number (or nonce) each time a signa...
Efficient authentication is one of important security requirements in mobile ad hoc network (MANET) routing systems. The techniques of digital signatures are generally considered a...
In this paper, we present a practical attack on the signature scheme SFLASH proposed by Patarin, Goubin and Courtois in 2001 following a design they had introduced in 1998. The att...
