New Public-Key Cryptosystem Using Divisor Class Groups
We show how to use ideal arithmetic in the divisor class group of an affine normal subring of K[X, Y] generated by monomials, where K is a field, to design new public-key cryptosystems, whose security is based on...

RSA Speedup with Residue Number System Immune against Hardware Fault Cryptanalysis
This article considers the problem of how to prevent the fast RSA signature and decryption computation with residue number system (or called the CRT-based approach) speedup from a hardware fault cryptanalysis ...

A Countermeasure against One Physical Cryptanalysis May Benefit Another Attack
Recently, many research works have been reported about how physical cryptanalysis can be carried out on cryptographic devices by exploiting any possible leaked information through side channels. In this paper,...

A Proposal for DoS-Defensive Internet Key Exchange
A variety of DoS attacks are incapacitating the Net infrastructures. IKEs can be easily targeted by these attacks because they force to process heavy computations, and an IKE is the beginning handshake procedu...

Permanent Fault Attack on the Parameters of RSA with CRT
Chinese remainder theorem has been widely employed to speedup the RSA computation. In this paper, one kind of permanent fault attack on RSA with CRT will be pointed out which exploits a permanent fault on the ...

Efficient Distributed Signcryption Scheme as Group Signcryption
The existing distributed signcryption is designed for distributing a signcrypted message to a designated group. However, it does not provide confidentiality of sender ID and its extension to a group signcrypti...

Public-Key Cryptosystems Based on Class Semigroups of Imaginary Quadratic Non-maximal Orders
In this paper we propose a key-exchange system and a public-key encryption scheme based on the class semigroups of imaginary quadratic non-maximal orders, the former is analogous to the Diffie-Hellman’s key-ex...

Hardware Fault Attack on RSA with CRT Revisited
In this paper, some powerful fault attacks will be pointed out which can be used to factorize the RSA modulus if CRT is employed to speedup the RSA computation. These attacks are generic and can be applicable ...

Security Analysis of Two Signcryption Schemes
Signcryption is a new cryptographic primitive that performs signing and encryption simultaneously, at a cost significantly lower than that required by the traditional signature-then-encryption approach. In thi...
