Collisions for RC4-Hash
RC4-Hash is a variable digest length cryptographic hash function based on the design of the RC4 stream cipher. In this paper, we show that RC4-Hash is not collision resistant. Collisions for any digest length can be found with an expected effort of less than 2 compression function evaluations. This is extended to multicollisions for RC4-Hash. Finding a set of 2 colliding messages has an expecte...
متن کاملPC-RC4 Algorithm: An Enhancement Over Standard RC4 Algorithm
RC4 is most widely used stream cipher. In many standard security protocols is used the RC4 like in Wi-Fi Protocol Access (WPA) and Wired Equivalence Privacy (WEP). Here we propose a new enhanced RC4 algorithm named as PC-RC4. It is an extension of standard RC4 Algorithm. The basic purpose of this enhancement is to making strong RC4 algorithm. RC4 stream cipher is basically two stages process na...

متن کاملQuad-RC4: Merging Four RC4 States towards a 32-bit Stream Cipher
RC4 has remained the most popular software stream cipher since the last two decades. In parallel to cryptanalytic attempts, researchers have come up with many variants of RC4, some targeted to more security, some towards more throughput. We observe that the design of RC4 has been changed a lot in most of the variants. Since the RC4 structure is quite secure if the cipher is used with proper pre...
