IDEA: A Cipher For Multimedia Architectures?
نویسنده
چکیده
MMX is a new technology to accelerate multimedia applications on Pentium processors. We report an implementation of IDEA on a Pentium MMX that is 1:65 times faster than any previously known implementation on the Pentium. By parallelizing four IDEA's we reach an unprecedented 78 Mbits/s throughput per output block on a 166MHz MMX. In the light of rapidly increasing popularity of multimedia applications, causing more dedicated hardware to be built, and observing that most of the current block ciphers do not bene t from MMX, we raise the problem of designing block ciphers (and encryption modes) fully utilizing the basic operations of multimedia.

Cipher text only attack on speech time scrambling systems using correction of audio spectrogram
Recently permutation multimedia ciphers were broken in a chosen-plaintext scenario. That attack models a very resourceful adversary which may not always be the case. To show insecurity of these ciphers, we present a cipher-text only attack on speech permutation ciphers. We show inherent redundancies of speech can pave the path for a successful cipher-text only attack. To that end, regularities ...
متن کاملNew Fixed Point Attacks on GOST2 Block Cipher
GOST block cipher designed in the 1970s and published in 1989 as the Soviet and Russian standard GOST 28147-89. In order to enhance the security of GOST block cipher after proposing various attacks on it, designers published a modified version of GOST, namely GOST2, in 2015 which has a new key schedule and explicit choice for S-boxes. In this paper, by using three exactly identical portions of ...
متن کاملCryptosystem Architectures for Very High Throughput Multimedia Encryption: the Rpk Solution
This paper presents a new approach to secure data encryption for high bit-rates communications. The proposed scheme is based on RPK, a new cryptographic algorithm based on the discrete logarithm problem implemented by a discrete exponentiation over finite Galois fields GF[2] and the Alternating Stop and Go as a Stream Cipher Block. The paper describes RPK architecture solutions yielding to low-...
متن کامل64-bit Block ciphers: hardware implementations and comparison analysis
A performance comparison for the 64-bit block cipher (Triple-DES, IDEA, CAST-128, MISTY1, and KHAZAD) FPGA hardware implementations is given in this paper. All these ciphers are under consideration from the ISO/IEC 18033-3 standard in order to provide an international encryption standard for the 64-bit block ciphers. Two basic architectures are implemented for each cipher. For the non-feedback ...
