Abstract
Due to the unique characteristics in IoT, such as heterogeneous and processing capacity limited terminals, complex in-formation transmission process and diverse applications, communication security is much more complicated compared with the In-ternet.Moreover, the existing single-path transportation security methods can not ensure safety and reduce computation complexi-ty at the same time, which makes these methods not suitable for the IoT.In view of the above issues, this thesis proposes an end-to-end secure communication method for the IoT, combining encryption and authentication technology with multipath transporta-tion.The basic idea was as follow: both terminals carried on key agreement scheme based on the Diffie-Hellman algorithm. Then, the sender used the session key obtained in the above stage and the symmetric encryption algorithm to encrypt data and split the encrypted data into segments, which were then sent to the receiver through multiple independent paths.Theoretical anal-ysis shows that this method can be better against security threats such as man-in-the-middle attack, key crack, with reduced com-puting complexity to a certain extent compared with the single-path transportation secure method.关键词
