3D: A Three-Dimensional Block Cipher

Jorge Nakahara

The main contribution of this paper is a new iterated secret- key block cipher called 3D, inspired by the AES cipher. The 3D cipher has an SPN design, operates on 512-bit blocks, uses 512-bit keys, it- erates 22 rounds, and employs a 3-dimensional state, i ...

(In)Security of an Efficient Fingerprinting Scheme with Symmetric and Commutative Encryption of IWDW 2005

We analyze the security of a fingerprinting scheme proposed at IWDW 2005. We show two results, namely that this scheme (1) does not provide seller security: a dishonest buyer can repudiate the fact that he redistributed a content, and (2) does not provide ...

On the Notions of PRP-RKA, KR and KR-RKA for Block Ciphers

Security of a modern block cipher is commonly measured in terms of its resistance to known attacks. While the provable security approach to block ciphers dates back to the first CRYPTO conference (1981), analysis of modern block cipher proposals typically ...

Node Cooperation in Hybrid Ad hoc Networks

Jean-Pierre Hubaux, Levente Buttyan, Naouel Ben Salem

A hybrid ad hoc network is a structure-based network that is extended using multi-hop communications. Indeed, in this kind of network, the existence of a communication link between the mobile station and the base station is not required: A mobile station t ...
