Method, Network Element, Mobile Terminal, System and Computer Program Product for Cryptographic Algorithm Negotiation

摘要

Method, network element, mobile terminal, system and computer program product are disclosed for negotiating cryptographic algorithm. The method comprises: receiving a first candidate list from the mobile terminal by the network element, wherein the first candidate list includes at least one candidate cryptographic algorithm supported by the mobile terminal and excludes at least one undesirable cryptographic algorithm even though it is supported by the mobile terminal; and selecting, from the first candidate list, a cryptographic algorithm supported by both the network element and the mobile terminal. As the undesirable cryptographic algorithm(s) is excluded from the first candidate list, the network element will be forced to choose more secure algorithms for communications with the mobile terminal.
