Abstract: A hardware encryption module with reconfigurable security algorithms for randomly selecting block ciphers, stream ciphers, and their components, for internet of things (IoT) and data security applications. A corresponding system contains a hardware number generator for generating unique secrets in digital and wireless communication protocols. The system contains a cryptographically secure pseudorandom number generator for creating deterministic random sequences for the reconfigurable logic module. The system contains a multiplexing scheme to send keys and cipher texts in accordance with a wireless communication protocol. The hardware encryption module can be used to reconfigure block cipher algorithms, modes of operation, key scheduling algorithms, confusion functions, and/or round orders, based on reconfigurable logic. One type of reconfigurable logic allows stream cipher algorithms and key mixing keys to be changed at random.

Abstract: Space-time coded massive (STCM) and space-frequency coded (SFC) massive multiple-input multiple-output (MIMO) wireless communication systems and methods of making and using the same are disclosed. The STCM-MIMO system utilizes two massive MIMO antenna arrays that transmit data over two or more channel vectors to a user with at least one receive antenna. This configuration permits the system to use the asymptotic orthogonal qualities of massive MIMO pre-coding to eliminate the interference from other users' channel vectors and signals. The system also maintains the diversity of space-time codes to recover lost data through treating each transmitting massive MIMO array similarly to a 2×1 Alamouti space-time code. The STCM-MIMO wireless system can significantly outperform those using space-time coding techniques only. The SFC massive MIMO wireless system may be similar to the STCM-MIMO wireless system, except for the encoder block.
