Cryptanalysis of Koyama Scheme
In this paper we analyze the security of Koyama scheme based on the singular cubic curve for some well known attacks. We provide an efficient algorithm for linearly related plaint...

Cryptanalysis and Security Enhancement of an Advanced Authentication Scheme using Smart Cards, and a Key Agreement Scheme for Tw
Abstract—In this work we consider two protocols for performing cryptanalysis and security enhancement. The first one by Song, is a password authentication scheme based on smart ...

A Fast Semantically Secure Public Key Cryptosystem Based on Factoring
The cryptosystem proposed by Koyama is not semantically secure. Also, it is not secure against partial known plaintext attack, linearly related plaintext attack and low exponent a...

Cryptanalysis of Certificateless Signcryption Schemes and an Efficient Construction without Pairing
Abstract. Certificateless cryptography introduced by Al-Riyami and Paterson eliminates the key escrow problem inherent in identity based cryptosystems. Even though building practic...

Security on Generalized Feistel Scheme with SP Round Function
This paper studies the security against differential/linear cryptanalysis and the pseudorandomness for a class of generalized Feistel scheme with SP round function called GFSP. We ...
