Chaotic maps-based three-party authenticated key agreement protocol using smart cards

With the gradual research on authentication issues, many researchers began to apply chaotic maps. Chaos theory has many good properties. It can achieve fast computing, and the time of encryption and decryption can be shortened to ensure smooth communication. Meanwhile, smart card technology is becoming a more practical technology. It has capabilities of security, confidentiality and identification, and can complete simple encryption and decryption operations. Based on the property of chaotic maps and smart cards, we proposed an authenticated key agreement protocol. In our protocol, we reach the goal of creatively combining chaotic maps and smart cards. Using chaotic maps and smart cards simplify our protocol and decrease the communication overhead, also improve the security of the authentication process.
