Securing MIMO Space-Time Block Coding Technique Over a Wireless Communication Links

A secure space-time block coding (i.e., a joint encryption and coding) scheme can provide both data secrecy and data reliability in one process to tackle problems in an insecure and unreliable communication channel. In this paper, an adaptive secure space-time block coding scheme based upon a normal Alamouti STBC codes is proposed. The crypto-analysis technique such as brute-force attacks over the proposed secure STBC indicates that the joint design can indeed provide both secrecy and data reliability very well. Such operations on Alamouti's STBC are achieved by adapting a pseudorandom sequence to control the key stream process over noisy channels.
