A generalized encryption scheme based on random graphs,th 0 and 1), but a probability of this event is very low. Such a generalization is sufficient for a large number of applications..An implementation of the scheme presented in the paper is based on random graphs. From the point of view of the worst-case complexity, the problem of decrypting is provab

As a graph with attributes assigned to its nodes and edges is an even more useful tool for the description of certain data structures than a directed graph, attributed elementary programmed graph grammars turn out to be adequate graph rewriting systems applicable in many areas of computer science.

A linear time algorithm to find the positioning of the guards is obtained.
