Title:
KEY DERIVATION ALGORITHM NEGOTIATION METHOD AND APPARATUS
Document Type and Number:
WIPO Patent Application WO/2019/062374
Kind Code:
A1
Abstract:
Provided in the present application are a key derivation algorithm negotiation method and an apparatus. The method comprises: a terminal checking a sent outgoing first key derivation algorithm and a received second key derivation algorithm; when checking is accurate and the first key derivation algorithm and the second key derivation algorithm are identical, determining the first key algorithm sent by the terminal has not been tampered with by an attacker; only then setting a negotiated third key derivation algorithm as a terminal key derivation algorithm, ensuring privacy of the negotiated key derivation algorithm, and thereby increasing communication security.
