Counting points in medium characteristic using Kedlaya's algorithm
Recently, many new results have been found concerning algorithms for counting points on curves over finite fields of characteristic p, mostly due to the use of p-adic... -
CTRU, a polynomial analogue of NTRU
CTRU, a new public-key cryptosystem is introduced. In this analogue of NTRU, the ring of integers is replaced by the ring of polynomials in one variable over a finite... -

The availability of a random number generator with high cryptographic qualities on a computer is one of the central issues of cryptographic implementations. HAVEGE... -
Modular Multiplication for FPGA Implementation of the IDEA Block Cipher
The IDEA block cipher is a symmetric-key algorithm which encrypts 64-bit plaintext blocks to 64-bit ciphertext blocks, using a 128-bit secret key. The security of IDEA... -
