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...
متن کاملALE: 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 ...
متن کاملAPE: Authenticated Permutation-Based Encryption for Lightweight Cryptography
The domain of lightweight cryptography focuses on cryptographic algorithms for extremely constrained devices. It is very costly to avoid nonce reuse in such environments, because this requires either a hardware source of randomness, or non-volatile memory to store a counter. At the same time, a lot of cryptographic schemes actually require the nonce assumption for their security. In this paper,...
متن کاملParallel authenticated encryption with the duplex construction
The authentication encryption (AE) scheme based on the duplex construction can no be paralellized at the algorithmic level. To be competitive with some block cipher based modes like OCB (Offset CodeBook) or GCM (Galois Counter Mode), a scheme should allow parallel processing. In this note we show how parallel AE can be realized within the framework provided by the duplex construction. The first...
