Pyjamask: Block Cipher and Authenticated Encryption with Highly Efficient Masked Implementation

Analysis of One-pass Block Cipher Based Authenticated Encryption Schemes

INT-RUP Analysis of Block-cipher Based Authenticated Encryption Schemes

Efficient FPGA Implementation of Block Cipher MISTY1

NESSIE is a 3-year research project (2000-2002). The goal of the project is to put forward some algorithms to obtain a set of the next generation of cryptographic primitives. In order to achieve this objective, the project needs to evaluate mathematical security levels and software/hardware implementations. This paper investigates the significance of an FPGA implementation of the block cipher M...

COFFE: Ciphertext Output Feedback Faithful Encryption On-Line Authenticated Encryption Without a Block Cipher

In this paper we introduce the first authenticated encryption scheme based on a hash function, called COFFE. This research has been motivated by the challenge to fit secure cryptography into constrained devices – some of these devices have to use a hash function, anyway, and the challenge is to avoid the usage of an additional block cipher to provide authenticated encryption. COFFE satisfies th...
