Problems solved by technology

However, all user private keys are uniformly generated by the KGC. If the KGC is no longer trusted or the private key of the KGC is stolen by an attacker, the security of the entire system will be lost.

Embodiment Construction

[0047] The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments.

[0048] The method of the present invention includes system initialization, user registration stage and user identity mutual authentication stage, such as figure 1 shown.

[0049] This example is implemented through the following steps:

[0050] Step 1. System initialization. First, the CA (certification center) selects a SEC 2 standard-recommended key length based on the prime number field GF(p) with a key length of 160bit elliptic curve E(GF(p)). The elliptic curve equation is:

[0051] the y 2 =(x 3 +ax+b)(mod p), a,b∈GF(p), and (4a 3 +27b 2 )mod p≠0;

[0052] Elliptic curve domain parameter is T=(p,a,b,G,n,h), CA randomly selects an integer s CA as its private key, and s CA ∈[2,n-2], by calculating P CA =s CA G obtains its public key;

[0053] Step 2, user registration phase, first users Alice and Bob generate their public / privat...

Abstract

The invention relates to a user identity mutual authentication method based on elliptic curve cryptography. The invention considers the characteristics of Ad Hoc network storage capability, computing capability and limited bandwidth, utilizes the self-authentication public key system and the intractability of the discrete logarithm problem of elliptic curve, reduces the number of interactions in the user identity authentication process, and accelerates the authentication speed. The method of the invention includes system initialization, user registration stage and user identity mutual authentication stage. The method of the invention ensures the mutual authentication of user identities and also realizes the function of session key negotiation, and the storage overhead, communication overhead, and calculation overhead are all small, and can resist replay attacks, man-in-the-middle attacks, masquerading and tampering attacks, and resist key leakage Masquerade attack, the generated one-time session key has forward security and backward security, which has higher security.

Description

technical field [0001] The invention belongs to the technical field of security and privacy protection in wireless communication, and in particular relates to a user identity mutual authentication method based on an elliptic curve code. Background technique [0002] As a special mobile ad hoc network, Ad Hoc network has a wide range of applications, especially suitable for tactical communication, emergency communication, temporary communication and other occasions. Mobile Ad Hoc networks do not require any infrastructure, have the characteristics of dynamic changes in network topology, limited storage capacity, computing power and energy, limited bandwidth, and poor network security, making Ad Hoc networks vulnerable to various attacks. Security is one of the key issues to be solved, and identity authentication is the first security barrier in the network system. For the Ad Hoc network, each node needs to be able to confirm the identity of the node communicating with it. If ...
