EFFICIENT SECURE SESSION ESTABLISHMENT FOR ANONYMITY IN 5G NETWORKS

摘要

The invention relates to a cryptographic method comprising an initialization phase for determining a provisional generating point G 'equal to a first product G' = [d '] G, where is a first random scalar forming a secret key of N bits and G is a point generating an elliptical curve; and determining a temporary key Q 'equal to a second product Q' = [d '] Q, where Q is a point on the elliptical curve forming a public key. During an encryption phase, a second random scalar forming a second secret key k of M bits, with M
