Submission to the CAESAR competition AES - COPA

Submission to the CAESAR competition AES - COBRA v 1

Hardware Performance of ELmD and ELmD(6,6)

ELmD (Encrypt-Linear mix-Decrypt) is a blockcipher based efficient authenticated encryption scheme, which is nonce misuse resistant, fully pipeline implementable. ELmD is a candidate for CAESAR competition and it has been selected for the second round. In this document, we first consider two versions of ELmDv2.0 (i) ELmD: full 10-round AES encryptiondecryption, no intermediate tag, fixed tag si...

General classification of the authenticated encryption schemes for the CAESAR competition

An Authenticated encryption scheme is a scheme which provides privacy and integrity by using a secret key. In 2013, CAESAR (the “Competition for Authenticated Encryption: Security, Applicability, and Robustness”) was co-founded by NIST and Dan Bernstein with the aim of finding authenticated encryption schemes that offer advantages over AES-GCM and are suitable for widespread adoption. The first...

A Submission to CAESAR Competition for Authenticated Encryption

This paper presents the Code-Book Authentication mode (CBA), a submission to the CAESAR competition for authenticated encryption. CBA is a blockcipher mode of encryption that provides confidentiality and authenticity for plaintexts and authenticity for associated data. The proposed mode improves the OCB mode in the sense that it saves up to one blockcipher call to encrypt and authenticate the p...

AES-Based Authenticated Encryption Modes in Parallel High-Performance Software

Authenticated encryption (AE) has recently gained renewed interest due to the ongoing CAESAR competition. This paper deals with the performance of block cipher modes of operation for AE in parallel software. We consider the example of the AES on Intel’s new Haswell microarchitecture that has improved instructions for AES and finite field multiplication. As opposed to most previous high-performa...
