ESTATE: A Lightweight and Low Energy Authenticated Encryption Mode

JAMBU Lightweight Authenticated Encryption Mode and AES-JAMBU

In this paper, we propose a lightweight authenticated encryption mode JAMBU. It only needs n-bit extra register for a block cipher with 2n-bit block size. It achieves n-bit authentication security when 2 bits are processed under a single key. When nonce (IV) is reused, the encryption security is similar to that of the CFB mode while the message authentication maintains strong security. We insta...

LAC: A Lightweight Authenticated Encryption Cipher

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...

ALE: AES-Based Lightweight Authenticated Encryption

In this paper, we propose a new Authenticated Lightweight Encryption algorithm coined ALE. The basic operation of ALE is the AES round transformation and the AES-128 key schedule. ALE is an online single-pass authenticated encryption algorithm that supports optional associated data. Its security relies on using nonces. We provide an optimized low-area implementation of ALE in ASIC hardware and ...

The 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...
