Probabilistic encryption scheme

WebbDefinition 1. The ciphertexts of an encryption scheme Enc(x) are called perfectly distinguishable, if D= 1 for some x 1;x 2 2 M. Lastly, there exist relaxations of perfect indistinguishability in order to develop more practical cryptosystems. A notable one is as follows. Definition 2. The ciphertexts of an encryption scheme Enc(x) An intuitive approach to converting a deterministic encryption scheme into a probabilistic one is to simply pad the plaintext with a random string before encrypting with the deterministic algorithm. Conversely, decryption involves applying a deterministic algorithm and ignoring the random padding. Visa mer 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. The term "probabilistic … Visa mer Example of probabilistic encryption using any trapdoor permutation: • x - single bit plaintext • f - trapdoor permutation (deterministic encryption algorithm) • b - hard core predicate of f Visa mer • Shafi Goldwasser and Silvio Micali, Probabilistic Encryption, Special issue of Journal of Computer and Systems Sciences, Vol. 28, No. 2, pages 270-299, April 1984 Visa mer The first provably-secure probabilistic public-key encryption scheme was proposed by Shafi Goldwasser and Silvio Micali, based on the hardness of the quadratic residuosity problem Visa mer Probabilistic encryption is particularly important when using public key cryptography.
