Multi-exponentiation algorithm based on binary GCD computation and its application to side-channel countermeasure
A series of algorithms for evaluation of multi-exponentiation are proposed based on the binary greatest common divisor algorithm. The proposed algorithms are inversion free and have the capability to evaluate ...

Security Analysis of the Authentication Modules of Chinese WLAN Standard and Its Implementation Plan
With the Canetti-Krawczyk (CK) model, we analyze the authentication module WAIs in the Chinese WLAN national security standard WAPI and its implementation plan respectively. The security weaknesses of WAI in t...

On the Security of the Authentication Module of Chinese WLAN Standard Implementation Plan
Compared with the original standard, the greatest change that WAPI (Chinese WLAN security standard) implementation plan made lies in the key-agreement protocol in WAI (Wireless Authentication Infrastructure). ...

Cryptanalysis of Two Protocols for RSA with CRT Based on Fault Infection
The technique of RSA private computation speedup by using Chinese Remainder Theorem (CRT) is well known and has already been widely employed in almost all RSA implementations. A recent CRT-based factorization ...

Relative Doubling Attack Against Montgomery Ladder
Highly regular execution and the cleverly included redundant computation make the square-multiply-always exponentiation algorithm well known as a good countermeasure against the conventional simple power analy...

Provably Secure Tripartite Password Protected Key Exchange Protocol Based on Elliptic Curves
Joux’s tripartite key agreement protocol is one of the most prominent developments in the area of key agreement. Although certificate-based and ID-based authentication schemes have been proposed to provide aut...

A Robust Double Auction Protocol Based on a Hybrid Trust Model
Recently, Wang and Leung proposed a set of double auction protocols with full privacy protection based on distributed ElGamal encryption. Unfortunately, their protocols are expensive in computation and are not...

Side Channel Cryptanalysis on SEED
The Korea standard block cipher, SEED, is a 128-bit symmetric block cipher with a more complex F function than DES. This paper shows that SEED is vulnerable to two types of side channel attacks, a fault analys...

An Improved Double Auction Protocol Against False Bids
M. Yokoo et al. analyzed some weaknesses in McAfee’s double auction (MCD) protocol and proposed a robust threshold price double auction (TPD) protocol against false-name bids. Unfortunately, as their protocol str...

How to Solve Key Escrow and Identity Revocation in Identity-Based Encryption Schemes
In identity-based cryptography, a user’s public key is easily derived from the user’s identity and a corresponding private key is generated for the user by a trusted third party, known as a Key Generation Cent...

Dragon: A Fast Word Based Stream Cipher
This paper presents Dragon, a new stream cipher constructed using a single word based non-linear feedback shift register and a non-linear filter function with memory. Dragon uses a variable length key and init...

Improvement on Ha-Moon Randomized Exponentiation Algorithm
Randomized recoding on the exponent of an exponentiation computation into a signed-digit representation has been a well known countermeasure against some side-channel attacks. However, this category of counter...

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...

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 ...
