Architecture based on MD5 and MD5-512 Bit Applications
Researchers have found many flaws in hash function such as MD5 algorithm. It has been one of the most widely used hash algorithm and it has been indicated that there is a security threat in the algorithm. Furthermore, a MD5 hash output may not offer sufficient protection in the near future. So in this paper, to provide higher security protection for MD5 and MD5-512 bit algorithm unified archite...
متن کاملCryptanalysis on HMAC/NMAC-MD5 and MD5-MAC
In this paper, we present the first distinguishing attack on HMAC and NMAC based on MD5 without related keys, which distinguishes the HMAC/NMAC-MD5 from HMAC/NMAC with a random function. The attack needs 2 queries, with a success probability 0.87, while the previous distinguishing attack on HMAC-MD5 reduced to 33 rounds takes 2 messages with a success rate of 0.92. Furthermore, we give distingu...
متن کاملModelling of High Quantum Efficiency Avalanche Photodiode
A model of a low noise high quantum efficiency n+np Germanium Photodiode utilizing ion implantation technique and subsequent drive-in diffusion in the n layer is presented. Numerical analysis is used to study the influence of junction depth and bulk concentration on the electric field profile and quantum efficiency. The performance of the device is theoretically treated especially at the wave-l...

Status of this Memo This memo provides information for the Internet community. This memo does not specify an Internet standard of any kind. Distribution of this memo is unlimited. Abstract MD5 is an authentication algorithm, which has been proposed as the default authentication option in IPv6. When enabled, the MD5 algorithm operates over the entire data packet, including header. This RFC addre...
متن کاملCollision Attack For MD5?
So far, two different 2-block collision differentials, both with 3-bit input differences for MD5, have been found by Wang etc in 2005 and Xie etc in 2008 respectively, and those differentials have been improved later on to generate a collision respectively within around one minute and half an hour on a desktop PC. Are there more collision differentials for MD5? Can a more efficient algorithm be...
