A method, apparatus and system for generating and distributing keys based on a Diameter server.

摘要

A method for generating and distributing keys based on the Diameter server in the mobile communication field is disclosed herein. The MN sends the NAR identifier to the PAR; after receiving the identifier, the PAR sends the NAR identifier and the MN identifier to the Diameter server; after receiving the identifiers, the Diameter server generates a random number first, then generates a shared key according to the random key, and then sends the shared key to the NAR and sends the random number to the MN; after receiving the random number, the MN generates a shared key. An apparatus and system for generating and distributing keys based on the Diameter server are also disclosed herein. The technical solution under the present invention avoids the domino effect and enhances security of the shared key.
