ABSTRACT:
The proof is provided by means of the following parameters: a public module n formed by the product of f prime factors pi, f>2; a public superscript v; m base numbers gi, m>1. The base numbers giare such that the two equations: x2≡gimod n and x2≡−gimod n cannot de solved in x in the ring of integers modulo n, and such that the equation xv≡gi2mod 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=2k, wherein k is a security parameter.
