A New Dedicated 256-Bit Hash Function: FORK-256
This paper describes a new software-efficient 256-bit hash function, FORK-256. Recently proposed attacks on MD5 and SHA-1 motivate a new hash function design. It is designed not only to have higher security but also to be faster than SHA-256. The performance of the new hash function is at least 30% better than that of SHA-256 in software. And it is secure against any known cryptographic attacks...
متن کاملA 256 X 256 CMOS Active Pixel Image Sensor
A 256 X 256 CMOS photo-gate active pixel image sensor is presented. The image sensor uses four MOS transistors within each pixel to buffer the photo-signal, enhance sensitivity, and suppress noise. The pixel size is 20 im X 20 jm and was implemented in a standard digital 0.9 pm single-polysilicon, double-metal, n-well CMOS process; leading to 25% fill-factor. Row and column decoders and counter...
متن کاملNESHA-256, NEw 256-bit Secure Hash Algorithm (Extended Abstract)
In this paper, we introduce a new dedicated 256-bit hash function: NESHA-256. The recently contest for hash functions held by NIST, motivates us to design the new hash function which has a parallel structure. Advantages of parallel structures and also using some ideas from the designing procedure of block-cipher-based hash functions strengthen our proposed hash function both in security and in ...
متن کاملStream Cipher HC - 256 ?
HC-256 is a software-efficient stream cipher. It generates keystream from a 256-bit secret key and a 256-bit initialization vector. The encryption speed of the C implementation of HC-256 is about 1.9 bits per clock cycle (4.2 cycles/byte) on the Intel Pentium 4 processor.
متن کاملNew FORK-256
The hash function FORK-256 was published at the first NIST hash workshop and FSE 2006. It consists of simple operations so that its performance is better than that of SHA-256. However, recent papers show some weaknesses of FORK-256. In this paper, we propose newly modified FORK-256 which has no microcoliisions and so is resistant against existing attacks. Furthermore, it is faster than the old ...
