KDP scheme of preliminary key distribution in discretionary security policy

Аннотация

A modification of the KDP scheme for the distribution of encryption keys is considered as applied to a distributed computer system with a discretionary security model. Limited access is specified as forbidden channels of data transmission. The scheme of preliminary key distribution is designed in such a way that it is impossible for forbidden channels to create a key-pair for the data exchange. An example of the construction of the proposed scheme is presented.
