Unbridle the Bit-Length of a Crypto-coprocessor with Montgomery Multiplicationd with such hardware Montgomery multipliers; however, due to progresses in factoring algorithms, the recommended bit length of public-key schemes such as RSA is steadily increasing, making the hardware quickly obsolete. Thanks to our double-size technique, one can re-use the existing hardware while

Delaying and Merging Operations in Scalar Multiplication: Applications to Curve-Based Cryptosystemso’s scalar multiplication algorithm where independent group operations are shown in an explicit way. We can thus merge several group operations and reduce the number of field operations by means of Montgomery’s trick. The results are that scalar multiplication on elliptic curves in even characterist

Multi-pass Fast Correlation Attack on Stream Ciphersof the involved linear feedback shift register as a whole and only use one sort of parity-checks to decode the corresponding linear code. In this paper we propose a new kind of attack, called multi-pass fast correlation attack, on stream ciphers. This kind of attack can make good use of different ki

Crossword Puzzle Attack on NLSich is introduced in this paper. We build the distinguisher by using linear approximations of both the non-linear feedback shift register (NFSR) and the nonlinear filter function (NLF). Since the bias of the distinguisher depends on the . value, which is a key-dependent word, we present the graph sh

Cryptanalysis of the Stream Cipher ABC v2key from about 2. random keys requires 6460 keystream bytes and 2. operations for each random key. Recovering the internal state of a weak key requires about 2. keystream bytes and 2. operations. A similar attack can be applied to break ABC v1 with much lower complexity than the previous attack on ABC v1.

In the late 1990s, the emergence of the Internet brought a period of relative chaos and interest in unstructured and “semistructured data” as
