In distributed environments, statements from a number of principals, besides the central trusted party, may influence the derivations of authorization decisions. However, existin...
Message Authentication Codes (MACs) are core algorithms deployed in virtually every security protocol in common usage. In these protocols, the integrity and authenticity of messag...
Amongst provably secure signature schemes, two distinct classes are of particular interest: the ones with tight reduction (e.g., RSA-PSS), and those which support the use of coupon...
Forgery and counterfeiting are emerging as serious security risks in low-cost pervasive computing devices. These devices lack the computational, storage, power, and communication r...
To sign with RSA, one usually encodes the message m as µ(m) and then raises the result to the private exponent modulo N. In Asiacrypt 2000, Coron et al. showed how to build a secu...
