A security multi-path transmission algorithm based onlink-security-level

For the reason that current concurrent multi-path transmission is lack for security consideration, a security multi-path transmission(SMT) algorithm was proposed based on link-security-level from security point of view. SMT first makes a security classification for different links, according to the security level of data packet, and then chooses higher level of security links for concurrent transmission. NS simulation shows that SMT algorithm can not only achieve the secure data transmission, but also has a reasonable performance. Security analysis shows SMT algorithm reduces the possibility of being intercepted, interrupts, and tampering.
