Abstract
Proof is established by means of the following parameters: m pairs of private values Qand public values Gm>1, a public module n made of the product of f first factors p, f>2, a public exponent v, linked to each other by relations of the type: G.Q=1 mod n or G=Qmod n. Said exponent v is such that v=2where k>1 is a security parameter. Public value Gis the square gof a base number gthat is lower than f first factors p, so that the two equations: x2=gmod n and x=−gmod n do not have a solution in x in the ring of the modulo n integers and such that the equation x=gmod n has solutions in x in the ring of the modulus n integers.
