A secure key agreement protocol based on chaotic maps∗
To guarantee the security of communication in the public channel, many key agreement protocols have been proposed. Recently, Gong et al. proposed a key agreement protocol based on chaotic maps with password sharing. In this paper, Gong et al.’s protocol is analyzed, and we find that this protocol exhibits key management issues and potential security problems. Furthermore, the paper presents a n...
متن کاملstudy of hash functions based on chaotic maps
توابع درهم نقش بسیار مهم در سیستم های رمزنگاری و پروتکل های امنیتی دارند. در سیستم های رمزنگاری برای دستیابی به احراز درستی و اصالت داده دو روش مورد استفاده قرار می گیرند که عبارتند از توابع رمزنگاری کلیددار و توابع درهم ساز. توابع درهم ساز، توابعی هستند که هر متن با طول دلخواه را به دنباله ای با طول ثابت تبدیل می کنند. از جمله پرکاربردترین و معروف ترین توابع درهم می توان توابع درهم ساز md4, md...
On the Security of a Chaotic Maps-based Three-party Authenticated Key Agreement Protocol
Chaotic map has been receiving increasing attention in the cryptographic literature. There are various scholars working on a particular type of authenticated key exchange protocol using chaotic map in the recent years. Very recently, Li et al. proposed a new three-party-authenticated key agreement protocol based on chaotic maps without storing a password table in a server. Compared with previou...
متن کاملOptimized Key Agreement Protocol Based on Chaotic
—Many key agreement protocols based on chaotic maps have been proposed to guarantee secure communications in the network. Recently, Wang et al. proposed a new key agreement protocol based on chaotic maps. But some issues exist in this protocol, such as anonymity, key distribution and management, and password problems. In order to improve the performance of Wang et al.’s protocol, this paper pr...
متن کاملCryptanalysis of a key agreement protocol based on chaotic Hash
With the rapid development of theory and application of chaos, more and more researchers are focusing on chaos based cryptosystems. Recently, Guo et al.’s [X. Guo, J. Zhang, Secure group key agreement protocol based on chaotic Hash, Information Sciences 180 (2010) 4069–4074] proposed a secure key agreement protocol based on chaotic Hash. They claimed that their scheme could withstand various at...
