Comparison 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 کاملAsymmetric Cryptosystems
Throughout the history of cryptography, hundreds of cryptosystems have been developed. The earliest ones, as well as many later ones, relied on the complete secrecy in transferring keys between the sender and recipient. These kinds of systems, called secret key cryptosystem, have just a single key which is used for both encryption and decryption; therefore, these systems are more frequently kno...
متن کاملAn asymmetric lossless image compression technique
Lossless image compression is often required in situations where compression is done once and decompression is to be performed a multiple number of times. Since compression is performed only once, the time required for compression is not a critical factor while selecting an appropriate compression scheme for such applications. What is more important is the amount of time and memory needed for d...
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...
متن کاملCryptanalysis of a technique to transform discrete logarithm based cryptosystems into identity-based cryptosystems
In this paper we analyse a technique designed to transform any discrete logarithm based cryptosystem into an identity-based cryptosystem. The transformation method is claimed to be efficient and secure and to eliminate the need to invent new identity-based cryptosystems. However, we show that the identity-based cryptosystem created by the proposed transformation method suffers from a number of ...
