Abstract. Even and Mansour [EM97] proposed a block cipher construction that takes a publicly computable random permutation oracle P and XORs different keys prior to and after appl...
We introduce Ad Hoc Anonymous Identification schemes, a new multi-user cryptographic primitive that allows participants from a user population to form ad hoc groups, and then prove...

The stream ciphers Py, Py6 designed by Biham and Seberry were promising candidates in the ECRYPT-eSTREAM project because of their impressive speed. Since their publication in Apri...
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. ...
Abstract This paper surveys the literature on certificateless encryption schemes. In particular, we examine the large number of security models that have been proposed to prove the...
