Abstract

This paper proposes a new symmetric cryptosystem based on nondeterministic finite automata. It is shown that nondeterminism allows to reduce the dependency of key automata on a large descriptional complexity and irreversibility of automata. Moreover, it is proven that the introduced cryptosystem has higher security and more efficient performance than its deterministic counterparts – Dӧmӧsi’s cryptosystem and its modified version.
