Probabilistic encryption goldwasser pdf
We replace deterministic block encryption by probabilistic encryption of single. This property enabled Goldwasser and Micali ill to device a scheme for Mental.A new probabilistic model of data encryption is introduced. Laboratory of.presenting the first probabilistic cryptosystem by Goldwasser and Micali.
متن کاملDense Probabilistic Encryption
This paper describes a method of dense probabilistic encryption. Previous probabilistic encryption methods require large numbers of random bits and produce large amounts of ciphertext for the encryption of each bit of plaintext. This paper develops a method of probabilistic encryption in which the ratio of ciphertext text size to plaintext size and the proportion of random bits to plaintext can...
متن کاملBenaloh's Dense Probabilistic Encryption Revisited
In 1994, Josh Benaloh proposed a probabilistic homomorphic encryption scheme, enhancing the poor expansion factor provided by Goldwasser and Micali’s scheme. Since then, numerous papers have taken advantage of Benaloh’s homomorphic encryption function, including voting schemes, private multi-party trust computation, non-interactive verifiable secret sharing, online poker. In this paper we show ...
متن کاملThe Multivariate Probabilistic Encryption Scheme MQQ-ENC
We propose a new multivariate probabilistic encryption scheme with decryption errors MQQ-ENC that belongs to the family of MQQ-based public key schemes. Similarly to MQQ-SIG, the trapdoor is constructed using quasigroup string transformations with multivariate quadratic quasigroups, and a minus modifier with relatively small and fixed number of removed equations. To make the decryption possible...
متن کاملEPOC: Efficient Probabilistic Public-Key Encryption (Submission to P1363a)
We describe a novel public-key cryptosystem, EPOC (Efficient Probabilistic Public-Key Encryption), which has two versions: EPOC-1 and EPOC-2. EPOC-1 is a public-key encryption system that uses a one-way trapdoor function and a random function (hash function). EPOC-2 is a public-key encryption system that uses a one-way trapdoor function, two random functions (hash functions) and a symmetric-key...
