碩士 === 元智大學 === 資訊工程學系 === 95 === The Stream Control Transmission Protocol (SCTP) is a transport layer protocol proposed by IETF in 2000. SCTP has many new features, such as multi-homing and multistreaming. However, its native design does not consider the wireless environments and the security demands. In the past, many studies were conducted either to improve the performance of SCTP in a wireless environment, or to enhance the security functionality. The consideration for both issues simultaneously is not found in past research. In this thesis, we propose a modified SCTP protocol called Collaborative Secure SCTP (CS-SCTP) with three enhancement methods, Partial Authentication, Two-level Key Encryption, and Assembly Chunk Encryption to improve the transmission performance of a secure SCTP connection in wireless networks based on the collaborative concept. CSSCTP preserves the performance advantages in Collaborative SCTP (C-SCTP) and the security functionality in Secure SCTP (S-SCTP). In the simulations, CS-SCTP outperforms S-SCTP in all different security requirements. If the security requirement is not rigid, the performance of CS-SCTP is comparable to that of C-SCTP.
