Abstract
Due to certain subtle and intimate links between the properties of traditional cryptosystems and chaotic systems, the application of chaotic systems to cryptography has received much attention from researchers in various disciplines. Key agreement schemes ensure secure communication and help two or more communicating parties establish a shared secure session key. Recently, many key agreement schemes that are based on chaotic maps have been proposed, some of which still require verification tables and remain insecure. Thus, we proposed an enhancement scheme to overcome these weaknesses – a concrete key agreement scheme that is based on the special properties of chaotic maps. This scheme provides secret and authenticated communication session keys and prevents known-key attacks.
