Reducing Key Length of the McEliece Cryptosystem

The McEliece cryptosystem is one of the oldest public-key cryptosystem ever designated. It is also the first public-key cryptosystem based on linear error-correcting codes. The main advantage of the McEliece cryptosystem is to have a very fast encryption and decryption functions but suffers from a major drawback. It requires a very large public key which makes it very difficult to use in many p...

A new key exchange cryptosystem

In this paper,we will present a new key exchange system based on linear algebra, which spend less operations but weaker in security than the DiffieHellman’s one.

A symmetric version of the McEliece public-key cryptosystem

This article exploits the fact that linear codes can correct twice the number of erasures as that of errors, allowing reduction in code size and providing the same level of security. decryption or both. The large code size of McEliece

A New Public-Key Cryptosystem

It is striking to observe that two decades after the discovery of public-key cryptography, the cryptographer’s toolbox contains only a dozen of asymmetric encryption schemes. This rarity and the fact that today’s most popular schemes had so far defied all complexity classification a.ttempts strongly motivates the design of new asymmetric cryptosystems. Interestingly, the crypt,ographic communit...

A Hybrid Cryptosystem using variable Length sub Key Groups and Byte Substitution

Hill cipher is developed using simple linear transformation. It is vulnerable to known-plaintext attack and there exist several methods in the direction of linear transformation to overcome the problems. HCM-EE is an improved method using Eigen value but it is linear and too many mathematical operations. In this study an attempt has been made to introduce nonlinearity to the linear transformati...
