Abstract

See full text

An encrypted communication apparatus determines a security protocol in IPsec to be applied to an IP packet, and calculates, based on the determined security protocol, a packet size which prevents the IP packet from being fragmented even if IPsec is applied to the IP packet. The packet size to be calculated is independent of an encryption algorithm and authentication algorithm which are actually specified by the determined security protocol.
