In this paper, we investigate the issues in the analysis and design of provably secure message authentication codes (MACs) Nested MAC (NMAC) and Hash based MAC (HMAC) proposed by ...
We present a constant-round non-malleable commitment scheme based on the existence of sub-exponential one-way functions and using a blackbox proof of security. As far as we know, t...
The Feistel-network is a popular structure underlying many block-ciphers where the cipher is constructed from many simpler rounds, each defined by some function which is derived fr...

Fugue is an intriguing hash function design with a novel shift-register based compression structure and has formal security proofs e.g. against collision attacks. In this paper, w...
Abstract. Radio Frequency Identification (RFID) systems are vulnerable to relay attacks (i.e., mafia, terrorist and distance frauds) when they are used for authentication purpose...
