Cryptanalysis of Hummingbird-1 [PDF]
, 2011 Hummingbird-1 is a lightweight encryption and message authentication primitive published in RISC '09 and WLC '10. Hummingbird-1 utilizes a 256-bit secret key and a 64-bit IV. We report a chosen-IV, chosen-message attack that can recover the full secret key with a few million chosen messages processed under two related IVs.
