A Conventional Authenticated-Encryption Mode
We propose a block-cipher mode of operation, EAX, for authenticated-encryption with associateddata (AEAD). Given a nonce N , a message M , and a header H, the mode protects the privacy of M and the authenticity of both M and H. Strings N, M, H E {0, 1} are arbitrary, and the mode uses 2→M/n∈ + →H/n∈ + →N/n∈ block-cipher calls when these strings are nonempty and n is the block length of the unde...
متن کاملThe AEM Authenticated-Encryption Mode
This note specifies AEM, a mode of operation giving authenticated encryption. AEM is a refinement to Rogaway, Bellare, and Black’s OCB mode [10], while OCB was, in turn, a refinement to Jutla’s IAPM [5]. AEM is also a successor to the work of Gligor and Donescu’s [4] and to the broader line of research that has defined and investigated authenticated encryption [1, 2, 6–8]. The acronym AEM stand...
متن کاملAnalysing the IOBC Authenticated Encryption Mode
The idea of combining a very simple form of added plaintext redundancy with a special mode of data encryption to provide data integrity is an old one; however, despite its wide deployment in protocols such as Kerberos, it has largely been superseded by provably secure authenticated encryption techniques. In this paper we cryptanalyse a block cipher mode of operation called IOBC, possibly the on...
متن کاملCryptanalysis of the EPBC Authenticated Encryption Mode
A large variety of methods for using block ciphers, so called ‘modes of operation’, have been proposed, including some designed to provide both confidentiality and integrity protection. Such modes, usually known as ‘authenticated encryption’ modes, are increasingly important given the variety of issues now known with the use of unauthenticated encryption. In this paper we show that a mode known...
متن کاملAuthenticated Encryption Mode of VEST Ciphers
This paper demonstrates operation of the authenticated encryption mode in VEST ciphers. All VEST ciphers operating in the authenticated encryption mode with infinite error propagation provide keyed message authentication at the same speed as their keystream generation, with negligible overhead and maintaining their security ratings.
