So far this methodology has only been used to prove that the O(log logN) least and most significant bits of any function with multiplicative access |which include the most common number theoretic trapdoor permutations| are secure. In this paper we show that the method applies to all bits of any function defined on a cyclic group of order N with multiplicative access for cryptographically interesting N. As a result, in this paper we reprove the security of all bits of RSA, the discrete logarithm in a group of prime order or the Paillier encryption scheme.application/pdfeng© Springer The final publication is available at Springer via http://dx.doi.org/10.1007/978-3-642-00468-1_29info:eu-repo/semantics/conferenceObjecthttp://dx.doi.org/10.1007/978-3-642-00468-1_29Bit securityList decodingOne-way functioninfo:eu-repo/semantics/openAccess
