Abstract

A cryptosystem for wireless communications, recently proposed by T.~Dean and A.~Goldsmith, is considered. That system can be regarded as a second revolution in cryptography because the confidentiality of the messages transmitted over a wireless massive MIMO-based channel is provided by the difference in the space locations of legal and illegal users and it does not require any secret key distribution. However our investigation shows that there is a chance of eavesdropping the cipher texts by using a suboptimal algorithm. Therefore we investigate some additional conditions for channel matrices and additive noises in order to provide a desired security. A combination of wiretap channel coding with a MIMO-based cryptosystem is also considered.
