Cryptanalysis of Hummingbird-2
Abstract: Hummingbird is a lightweight encryption and message authentication primitive published in RISC’09 and WLC’10. In FSE’11, Markku-Juhani O.Saarinen presented a differential divide-and-conquer method which has complexity upper bounded by 2 operations and requires processing of few megabytes of chosen messages under two related nonces (IVs). The improved version, Hummingbird-2, was presen...
متن کاملThe 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 کاملRelated-Key Attacks Against Full Hummingbird-2
We present attacks on full Hummingbird-2 which are able to recover the 128-bit secret keys of two black box cipher instances that have a certain type of low-weight XOR difference in their keys. We call these highly correlated keys as they produce the same ciphertext with a significant probability. The complexity of our main chosen-IV key-recovery attack is 2. The first 64 bits of the key can be...
متن کاملA Cryptanalysis of HummingBird-2: The Differential Sequence Analysis
Hummingbird-2 is one recent design of lightweight block ciphers that enables compact hardware implementations, ultra-low power consumption and stringent response time as specified in ISO18000-6C. In this paper, we present cryptanalytic results on the full version of this cipher using two pairs of related keys. We discover that the differential sequences for the last invocation of the round func...
متن کاملHummingbird Ltd.
The Network File System (NFS) version 4 is a distributed filesystem protocol which owes heritage to NFS protocol version 2, RFC 1094, and version 3, RFC 1813. Unlike earlier versions, the NFS version 4 protocol supports traditional file access while integrating support for file locking and the mount protocol. In addition, support for strong security (and its negotiation), compound operations, c...
