Advance in Keyless Cryptography

Коржик Валерий Иванович, Vladimir Starostin, Victor Yakovlev +3 more

The term “keyless cryptography” as it is commonly adopted, applies to secure message transmission either directly without any key distribution in advance or as key sharing protocol between communicating users, based on physical layer security, before ordinary encryption/decryption procedures. In the current chapter the results are presented concerning to keyless cryptography that have been obtained by authors recently. Firstly Shamir’s protocol of secure communication is considered where commutative encryption procedure is executed. It has been found out which of the public key algorithms can be used with such protocol. Next item of consideration concerns Dean’s and Goldsmith’s cryptosystem based on multiple-input, multiple-output (MIMO) technology. It has been established under which conditions this cryptosystem is in fact secure. The third example under consideration is EVSkey scheme proposed recently by D. Qin and Z. Ding. It has been proven that such key distribution method is in fact insecure, in spite of the authors’ claims. Our main result is a description of a key sharing protocol executing over public noiseless channels (like internet) that provides a key sharing reliability and security without any cryptographic assumptions.The term “keyless cryptography” as it is commonly adopted, applies to secure message transmission either directly without any key distribution in advance or as key sharing protocol between communicating users, based on physical layer security, before ordinary encryption/decryption procedures.

Survey of Wiretap Channel Security Model

Mengjie Huang, Ziyi Li, Dingding Jia +1 more

Wiretap Channel model was first proposed by Wyner in 1974 and has become the basis of secure communication technologies at physical layer. Compared with the public key cryptography, which is almost developed synchronously, it only depends on the assumptions of physical channel rather than computational assumptions. Abundant work in this area has been developed, but there are only heuristic results for security definitions and evaluation methods until 2012. This paper provides a survey of the wiretap channel model, focuses on formal security definitions and keyless secure schemes of it.Wiretap Channel model was first proposed by Wyner in 1974 and has become the basis of secure communication technologies at physical layer.
