We show that the widely deployed RSA-OAEP encryption scheme of Bellare and Rogaway (Eurocrypt 1994), which combines RSA with two rounds of an underlying Feistel network whose hash...
The ASIRRA CAPTCHA [6], recently proposed at ACM CCS 2007, relies on the problem of distinguishing images of cats and dogs (a task that humans are very good at). The security of AS...
Recently, based on RSA and discrete logarithm with composite modulus, Huang and Chang proposed two multisignature schemes with distinguished signing authority and claimed that the...
Distributed Denial Of Service (DDoS) attacks are familiar threats to Internet users for more than ten years. Such attacks are carried out by a “Bot net”, an army of zombie hos...
A theme of recent side-channel research has been the quest for distinguishers which remain eective even when few assumptions can be made about the underlying distribution of the m...
