In this paper we present a new 128-bit block cipher called Square. The original design of Square concentrates on the resistance against dierential and linear cryptanalysis. Howeve...
Matsui's linear cryptanalysis for iterated block ciphers is generalized to an attack called. This attack exploits a weakness that can be described by an e ective partition-pa...
We present a new micropayment scheme based on the use of “electronic lottery tickets.” This scheme is exceptionally efficient since the bank handles only winning tickets, inste...
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. ...
