暗号処理方法、暗号処理装置、復号処理方法および復号処理装置
Document Type and Number:
Japanese Patent JP5205075
Kind Code:
B2
Abstract:
Provided is an encryption processing device which can effectively improve an encryption processing performance of a secure multi-media communication. The encryption processing device (100) includes: storage means (162) which stores secure processing information containing an identification condition for identifying a packet requiring an encryption/decryption process or an authentication process; transmission means (112) which transmits a multi-media packet in a plain text to a virtual network interface (140); correction means (160) which executes an encryption process or an authentication process on the multi-media packet if the multi-mediapacket coincides with the identification condition and corrects the payload of the secure multi-media packet so as to be matched with a security protocol; and replacement means (130) which transfers the secure multi-media packet transmitted to the virtual network interface (140) to an inherent network interface (150).
