چکیده
In 2004, Hwang et al. proposed an efficient user identification scheme based on ID-based cryptosystem. This paper will show that Hwang et al.’s scheme is not secure by presenting an forgery attack on them.

Cryptanalysis of an Efficient User Identification Scheme Based on ID-Based Cryptosystem
In 1998, Tseng and Jan proposed a lightweight interactive user identification protocol based on ID-based cryptography. Recently, Hwang et al. modified their protocol to reduce the responding and waiting time for wireless network applications. In this letter, we show that their scheme is vulnerable to impersonation attacks. key words: cryptanalysis, user identification, ID-based cryptosystem, wi...
متن کاملAn efficient secure channel coding scheme based on polar codes
In this paper, we propose a new framework for joint encryption encoding scheme based on polar codes, namely efficient and secure joint secret key encryption channel coding scheme. The issue of using new coding structure, i.e. polar codes in Rao-Nam (RN) like schemes is addressed. Cryptanalysis methods show that the proposed scheme has an acceptable level of security with a relatively smaller ke...

Two identification schemes based on the Maurer-Yacobi ID-based cryptosystem are analysed and shown to suffer from serious security problems.
متن کاملAn Efficient and Secure ID-based Remote User Authentication Scheme using Smart Card
The User Authentication mechanism technology has enjoyed strong growth in recent year, but security threats and facing attacks in authentication have grown equally fast. Today, there are many potential attacks that are targeted at authentication including insider attack, masquerade attack, server spoofing attack, parallel session attack, offline password guessing attack and many more. Recently,...
متن کاملCryptanalysis and improvement of an ID-based ad-hoc anonymous identification scheme at CT-RSA 05
An ad-hoc anonymous identification scheme is a new multiuser cryptographic primitive that allows participants from a user population to form ad hoc groups, and then prove membership anonymously in such groups. Recently, Nguyen [11] proposed an ID-based ad-hoc anonymous identification scheme from bilinear pairings. However, in this paper, we propose an attack on Nguyen’s ID-based ad-hoc anonymou...
