A method and apparatus for processing an encrypted call, a terminal, and a KMC. Embodiments of the present invention comprise: when a first terminal detects that a user initiates a call encryption request, collecting biological characteristic information for identifying a user identity, and encrypting the biological characteristic information, so as to obtain encrypted biological characteristic information; sending a first key negotiation signaling, carrying the encrypted biological characteristic information, to a key management center (KMC); receiving a first negotiation success response message returned by the KMC after the encrypted biological characteristic information is decrypted and is successfully compared with pre-saved biological characteristic information corresponding to the first terminal, the first negotiation success response message carrying a session key allocated by the KMC for a session between the first terminal and a second terminal; and encrypting a call according to the session key carried in the first negotiation success response message. The technical solutions provided by the embodiments of the present invention prevent the problem of privacy leakage of an owner due to the fact that an illegal user encrypts a call by using a first terminal, thereby guaranteeing the security of the call. |
