Abstract: The openness of wireless links and the mobility of nodes in mobile IP bring potential security threats to the registration of mobile nodes. To address the problem of registration security of mobile nodes, a USBKey aided registration authentication protocol is proposed. The protocol protects the mobile node’s private key through the USBKey to enhance the security of mobile registration, and realizes the authentication of relevant protocol entities and encryption of registration information by combining the digital envelope technology and digital signature technology. The analysis shows that the protocol can guarantee the integrity and confidentiality of the registration information, effectively resist the common security attack, ensure the registration security of the mobile nodes, and has less registration authentication delay than that of the related protocols.
