Security is an essential requirement in any data communication system because a cyber criminal might try to break into it at any point by any means possible. A key agreement procedure is a necessary technique to ensure the security of data communication by way of encryption and mutual authentication. This article proposes a simple key agreement scheme on the basis of chaotic maps for VSAT satellite communications. The new scheme keeps the advantages of all chaotic maps-based public key cryptosystems, providing a secure function of session key agreement. Based on the intractability of chaotic map discrete logarithm problem and chaotic map Diffie-Hellman problem, the security of this new scheme has been proven to be robust enough against all the well-known cryptographical attacks with perfect forward secrecy provided. In addition, compared with similar schemes that serve the same purposes, the proposed scheme demands a lower computation cost. With all the previous features put together, the proposed scheme is extremely suitable for the use in very small aperture terminal satellite communication environments.
