Document Type and Number:
WIPO Patent Application WO/2017/152423
Kind Code:
A1
Abstract:
Disclosed are a key negotiation method, device and system, relating to the field of wireless communications and used for solving the problem of a low degree of encryption when a BNN-IBS is applied to a D2D wireless communication network for key negotiation. The key negotiation method comprises: when a key generation device sends a public key and a private key of a first user equipment to the first user equipment, when the key generation device sends a public key and a private key of a second user equipment to the second user equipment, when the first user equipment sends a first signature message to the second user equipment, and when the second user equipment sends a second signature message to the first user equipment, performing homomorphic encryption.
