Patent ID: 8266422

Claim:
A network security processing method for selecting one of software and hardware cryptographic modules by means of multimedia session information, comprising: subjecting a plurality of packets of a multimedia session to signaling processing so as to obtain multimedia session information contained in the multimedia session, the multimedia session information including a media type and a codec type; subjecting the multimedia session to a key authentication negotiation; and according to the multimedia session information and a cryptographic module determination database, making a determination to activate one of the hardware cryptographic module and the software cryptographic module, the hardware cryptographic module managing network security processing of the packets of the multimedia session if the hardware cryptographic module is activated, the software cryptographic module managing network security processing of the packets of the multimedia session if the software cryptographic module is activated, wherein the cryptographic module determination database stores at least one of the media type and the codec type in association with one of a use of the hardware cryptographic module and a use of the software cryptographic module, and wherein the making a determination searches the cryptographic module determination database to determine the use of the hardware cryptographic module or the use of the software cryptographic module according to at least one of the media type and the codec type in the obtained multimedia session information.
