Embodiment Construction

[0018] When the present invention is used for identity authentication, it is assumed that user A wants to conduct confidential communication with user B, and needs to transmit the secret session key on an insecure channel. In the present invention, user A and user B share an elliptic curve, and an elliptic curve is provided here as follows:

[0019] E: y 2 =x 3 +ax+b mod n

[0020] in

[0021] p=6277101735386680763835789423207666416083908700390324961279;

[0022] seedE = 0x3045ae6fc8422f64ed579528d38120eae12196d5;

[0023] r = 0x3099d2bbbfcb2538542dcd5fb078b6ed5f3d6fe2c745de65;

[0024] a=-3;

[0025] b=0x64210519e59c80e70fa7e9ab72243049feb8deecc146b9b1;

[0026] h=1

[0027] The order of the elliptic curve is:

[0028] n=6277101735386680763835789423176059013767194773182842284081;

[0029] It is a prime number.

[0030] The selection of the base point P with order n is:

[0031] P = (xG, yG) where

[0032] xG=0x188da80eb03090f67cbf20eb43a18800f4ff0afd82ff1012;

Abstract

The present invention discloses an identity identification method based on public key certification on the elliptic curve. It is an identify identification method by proceeding from discrete logarithm problem on the elliptic curve and utilizing anti-collision miscellaneous function and public key certificate to make identity identification. It has provable safety and rapid operation speed. It canbe extensively used in the fields of identity identification of network communication, electronic business, bill, certificate and identify identification, etc.

Description

technical field [0001] The invention relates to an identity authentication method for confidential or safe communication, in particular to an identity authentication method based on a public key certificate on an elliptic curve. Background technique [0002] Identity authentication refers to the confirmation technology of user identity, which is the first and most important line of defense of network security. Various applications and computer systems in the network need to confirm the legitimacy of a user through identity authentication, and then determine the user's personal data and specific permissions. When using a credit card in life, you need to enter a password, and you need to show your ID card when you get on the plane, etc. These are all application examples of identity authentication. The existing identity authentication methods generally include identity authentication methods based on zero-knowledge theory, identity authentication met...
