Abstract
The proof is provided by means of the following parameters: a public module n formed by the product of f prime factors p, f>2; a public superscript v; m base numbers g, m>1. The base numbers gare such that the two equations: x≡gmod n and x≡−gmod n cannot de solved in x in the ring of integers modulo n, and such that the equation x≡gmod n can be solved in x in the ring of integers modulo n in the case where the public superscript v is in the form v=2, wherein k is a security parameter.
