<p>The invention discloses a method of freely selecting encrypting arithmetic for realizing communication of secrecy, characterised in that: increasing the bit of consumer index (CI), synchronously increasing the judgement of encrypting arithmetic sustained by the CI, current user and the net; When corn net (CN) sustains more than one kind of encrypting arithmetic, if CI=1 and user equipment (UE) and CN both sustain standard encrypting arithmetic, selecting the standard encrypting arithmetic as encrypting arithmetic of communication; or, interrupting link of communication; if CI=0, UE and CN both sustain the independently developed unstandarded encrypting arithmetic, selecting the encrypting arithmetic; of interrupting the link of communication; When only sustaining the standard encrypting arithmetic if UE sustains the standard encrypting arithmetic, directly selecting the standard encrypting arithmetic; or, interrupting link of communication. The method makes user take available encrypting arithmetic for communication of secrecy, and satisfying the requirement of independently selecting arithmetic, further ensuring user benefit and service quality.</p> |
