<p>Method making it possible to generate encryption keys and to exchange the parameters making it possible to generate said keys in a network comprising n entities X wishing to exchange data, characterized in that it comprises at least the following steps: o the n entities elect a common generator of arrays (G M (?)), o at least one of the entities X communicates these values (? i) via several different routing paths Ci, plus a reference random number N x, N y, o each entity X, Y generates an array T s, o each entity X, Y composes a secret key on the basis of the array (T s) generated and on the basis of several values indexed by several pairs ((i, j),(k,l);...;(o, p)) of said array so as to create its secret value, o the encrypted random number of a first entity X is returned to a second entity Y, one of the n entities X, Y at least compares the consistency of the two values N x after decryption with its own key Kxs.</p> |
