چکیده
It is based on the intractability of Quadratic Residuosity Assumption modulo a composite N . Very roughly, we select uniformly at random Quadratic Residues from ZN to encrypt 0 bit and to encrypt 1 bit we select quadratic non-residue from ZN . However, since the distribution of quadratic residues and quadratic non-residues are not same in ZN we confine ourselves to a subset of ZN where the number of quadratic residues is equal to the number of quadratic non-residues.

متن کاملPerformance Analysis of Goldwasser-Micali Cryptosystem
Probabilistic encryption is the use of randomness in an encryption algorithm, so that when encrypting the same message several times it will, in general, yield different ciphertexts. To be semantically secure, that is, to hide even partial information about the plaintext, an encryption algorithm must be probabilistic. The Goldwasser–Micali cryptosystem is an asymmetric key encryption algorithm ...
متن کاملEfficient Cryptosystems from 2 k -th Power Residue Symbols
Goldwasser and Micali (1984) highlighted the importance of randomizing the plaintext for public-key encryption and introduced the notion of semantic security. They also realized a cryptosystem meeting this security notion under the standard complexity assumption of deciding quadratic residuosity modulo a composite number. The Goldwasser-Micali cryptosystem is simple and elegant but is quite was...
متن کاملAn Application of the Goldwasser-Micali Cryptosystem to Biometric Authentication
This work deals with the security challenges in authentication protocols employing volatile biometric features, where the authentication is indeed a comparison between a fresh biometric template and that enrolled during the enrollment phase. We propose a security model for biometric-based authentication protocols by assuming that the biometric features to be public. Extra attention is paid to t...
متن کاملIntroduction to Modern Cryptography
Forewords This book contains a set of lecture notes that I wrote for an offering of a " Topics in Cryptography " course at Columbia University, in the Spring 1999. It is not clear what use one can make of these notes. The main purpose was to integrate the treatment of the Goldwasser-Bellare lecture notes with some additional proofs, without getting into the level of rigor of Goldreich's book. I...
