Abstract :
Hummingbird-1 is a lightweight cryptographic algorithm appropriated for use within resource-constrained environments, which has 256-bit key and encrypt a 16-bitdata in one operation. In this paper, a cryptanalysis ofHummingbird-1 is given which shows a shortcut attack on the internal 16-bit block length, 64-bit key block cipher. The results indicate that Hummingbird-1 may not achieve the security goal with its design choices.
