Webcipher which have been discussed sine Rabin[13] given the first model of that kind of structure. As pointed out by BRS the block cipher approach has been less widely used for variety of reasons, and the emergence of the AES[6] has somewhat modified this landscape, especially recently the MD5 and SHA1 were attacked[1][2][16][17]. WebRSA is the most widespread and used public key algorithm. Its security is based on the difficulty of factoring large integers. The algorithm has withstood attacks for more than 30 years, and it is therefore considered reasonably secure for new designs. The algorithm can be used for both confidentiality (encryption) and authentication (digital ...
