Abstract. SPEED is a private key block cipher. It supports three variable parameters: (1) data length — the length of a plaintext/ciphertext of SPEED can be 64, 128 or 256 bits. ...
Many applications require protection of secret or sensitive information, from sensor nodes and embedded applications to large distributed systems. The confidentiality of data can b...
For years, the cryptographic community has searched for good nonlinear functions. Bent functions, almost perfect nonlinear functions, and similar constructions have been suggested ...
The design of cryptographic hash functions is a very complex and failure-prone process. For this reason, this paper puts forward a completely modular and fault-tolerant approach to...
A vast amount of literature on stream ciphers is directed to the cryptanalysis of LFSR-based filters and combiners, resulting in various attack models such as distinguishing attac...
