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 ...
متن کاملDmd050245 256..262
There is increasing evidence that pregnancy alters the function of drug-metabolizing enzymes and drug transporters in a gestationalstage and tissue-specific manner. In vivo probe studies have shown that the activity of several hepatic cytochrome P450 enzymes, such as CYP2D6 and CYP3A4, is increased during pregnancy, whereas the activity of others, such as CYP1A2, is decreased. The activity of s...
