Hidden Real Modulus RSA Cryptosystem

Attack on RSA Cryptosystem

The RSA cryptosystem is most widely used cryptosystem it may be used to provide both secrecy and digital signatures and its security is based on the intractability of the integer factorization. The security of RSA algorithm depends on the ability of the hacker to factorize numbers. New, faster and better methods for factoring numbers are constantly being devised. The Trent best for long numbers...

Improvement in RSA Cryptosystem

Boneh and Shacham gave a nice survey on four variants (Batch RSA, MultiPrime RSA, MultiPower RSA, Rebalanced RSA). Rebalanced RSA and MultiPower RSA were then combined to increase the decryption/signature generation performance. This combination theoretically improves the decryption/signature generation time about 14 times than RSA with CRT and about 56 times than the standard RSA with key size...

The RSA Cryptosystem

This paper explores the history and mathematics be­ hind the RSA cryptosystem, including the idea of public key cryp­ tosystems and number theory. It outlines the applications of RSA including secure information transfers and electronic signatures. It also analyzes why RSA is a secure way of transmitting information and the ways that it has been defeated in the past. In particular, we focus on ...

Modified Montgomery for RSA Cryptosystem

Encryption and decryption in RSA are done by modular exponentiation which is achieved by repeated modular multiplication. Hence efficiency of modular multiplication directly determines the efficiency of RSA cryptosystem. This paper designs a Modified Montgomery Modular Multiplication in which addition of operands is computed by 4:2 compressor. The basic logic operations in addition are partitio...
