PACKET ENCRYPTION METHOD, PACKET DECRYPTION METHOD AND DECRYPTION DEVICE

摘要

A packet encryption method for encrypting an IP packet communicated based on an internet protocol is provided. The packet encryption saves fragment information included in an IP header in an area other than the IP header, clears the fragment information included in the IP header, encrypts the IP packet in which the fragment information included in the IP header is cleared, and outputs the encrypted IP packet.
