SECURITY ENCRYPTED NETWORK ACCESS IDENTIFIER FOR IP MOBILITY SYSTEMS

摘要

The present invention improves the security of communications in an IP mobile communications systems by creating a Secured Generalized Network Identifier (SG-NAI). The SG-NAI is encrypted and decrypted using a key-based encryption and decryption algorithm. The present invention reduces the data overhead for communications over Mobile IP systems compared to existing methods of encrypting and decrypting IP data packets.
