On non-abelian homomorphic public-key cryptosystems
An important problem of modern cryptography concerns secret public-key computations in algebraic structures. We construct homomorphic cryptosystems being (secret) epimorphisms f : G → H, where G,H are (publically known) groups and H is finite. A letter of a message to be encrypted is an element h ∈ H, while its encryption g ∈ G is such that f(g) = h. A homomorphic cryptosystem allows one to per...
متن کاملHomomorphic public-key cryptosystems over groups and rings
We propose a new homomorphic public-key cryptosystem over arbitrary nonidentity nite group based on the di culty of the membership problem for groups of integer matrices. Besides, a homomorphic cryptosystem is designed for the rst time over nite commutative rings.
متن کاملPublic key cryptosystems based on boolean permutations and their applications
In this paper we propose the use of Boolean permutations to design public key cryptosystems. The security of the cryptosystems is based on the diiculty of inverting Boolean permutations. Using two Boolean permutations for which the inverses are easy to nd, one can construct a composite Boolean permutation which is hard to invert. The paper proposes three such Boolean permutation based public ke...
متن کاملComparison of two Public Key Cryptosystems
Since the time public-key cryptography was introduced by Diffie andHellman in 1976, numerous public-key algorithms have been proposed. Some of thesealgorithms are insecure and the others that seem secure, many are impractical, eitherthey have too large keys or the cipher text they produce is much longer than theplaintext. This paper focuses on efficient implementation and analysis of two mostpo...
متن کاملKey-Insulated Public Key Cryptosystems
Cryptographic computations (decryption, signature generation, etc.) are often performed on a relatively insecure device (e.g., a mobile device or an Internet-connected host) which cannot be trusted to maintain secrecy of the private key. We propose and investigate the notion of key-insulated security whose goal is to minimize the damage caused by secret-key exposures. In our model, the secret k...
