PCT No. PCT/FR96/01546 Sec. 371 Date Sep. 24, 1997 Sec. 102(e) Date Sep. 24, 1997 PCT Filed Oct. 3, 1996 PCT Pub. No. WO97/13342 PCT Pub. Date Apr. 10, 1997Method of public key cryptography based on the discrete logarithm that makes use of the computation of the variable r=gk modp where p is a prime number called a modulus, the exponent k is a random number usually with a length of N bits and g is an integer called a base, wherein an entity E carries out operations of authentication and/or of signature, including exchanges of signals with another entity in which this variable comes into play.
