A SCTP-based authentication protocol: SCTPAP

Multihoming is among the features of SCTP (Stream Control Transmission Protocol), which makes it more robust and efficient than TCP(Transmission Control Protocol)but more vulnerable under attack. Nevertheless, a strong security can degrade the QoS(Quality of Service) by adding additional delay. Therefore, we propose in this paper, a secure authentication protocol that supports the establishment of multiple connections to protect multihoming networks with the least number of messages, number of parameters in each message and number of communicating nodes. The proposed scheme provides lower delay of authentication and protects against several attacks. Our devised protocol is analyzed using SPAN (Security Protocol Animator) for AVISPA (Automated Validation of Internet Security Protocols and Applications) tool. The obtained validation results show that the scheme is safe.
