This paper develops several new techniques of cryptanalyzing MACs based on block ciphers, and is divided into two parts. The first part presents new distinguishers of the MAC construction ALRED and its specific instance ALPHA-MAC based on AES. For the ALRED construction, we first des...
In this paper, we revisit the security of several message authentication code (MAC) algorithms based on block ciphers, when instantiated with 64-bit block ciphers such as DES. We essentially focus on A Joux,G Poupard,J Stern - DBLP 被引量: 32发表: 2003年 Basing PRFs on Constant-Query We...

We propose a new mode of operation, enciphered CBC, for domain extension of length-preserving functions (like block ciphers), which is a variation on the popular CBC mode of operation. Our new mode is twice slower than CBC, but has many (property-preserv
We describe a new cryptanalysis technique for double-block MACs based on finding quadruples of messages with four pairwise collisions in halves of the state. We show how to detect such quadruples inSUM-ECBC,PMAC+,3kf9,GCM-SIV2and their variants with\(\mathcal {O}(2^{3n/4})\)queries,...
MACs can be built from scratch (SipHash, Chaskey), from block ciphers (CBC-MAC, PMAC), from hash functions (HMAC), or from universal hash functions (GMAC, Poly1305). Constructions based on a lower level primitive are usually ... Gaëtan Leurent 被引量: 0发表: 2015年 Generic State-...
We revisit the double-pipe construction introduced by Lucks at Asiacrypt 2005. Lucks originally studied the construction for iterated hash functions and showed that the approach is effective in improving security against various types of collision and (second-)preimage attacks. Instead, in this paper...
to optimize new block ciphers—it seems a shame to squander some of this efficiency with an unnecessary application of E. Moreover, in practical settings we often wish to MAC very short messages, where saving one invocation of the block cipher can be a significant performance gain. ...
