Beetle Family of Lightweight and Secure Authenticated Encryption Ciphers

Artemia: a family of provably secure authenticated encryption schemes

Authenticated encryption schemes establish both privacy and authenticity. This paper specifies a family of the dedicated authenticated encryption schemes, Artemia. It is an online nonce-based authenticated encryption scheme which supports the associated data. Artemia uses the permutation based mode, JHAE, that is provably secure in the ideal permutation model. The scheme does not require the in...

Authenticated 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.

LAC: A Lightweight Authenticated Encryption Cipher

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 Hummingbird-2 Lightweight Authenticated Encryption Algorithm

Hummingbird-2 is an encryption algorithm with a 128-bit secret key and a 64-bit initialization vector. Hummingbird-2 optionally produces an authentication tag for each message processed. Like it’s predecessor Hummingbird-1, Hummingbird-2 has been targeted for low-end microcontrollers and for hardware implementation in lightweight devices such as RFID tags and wireless sensors. Compared to the p...
