We present a collision attack on the hash function HAS-160 reduced to 53-steps. The attack has a complexity of about 235 hash computations. The attack is based on the work of Cho e...

Steganography embeds a secret message in an innocuous cover-object. This paper identifies three cover-specific redundancies of executable programs and presents steganographic techn...
