Abstract

The invention discloses a heterogeneous network end-to-end authentication secret key exchange method based on a space-sky information network. The method includes a mobile terminal registering step, a secret key establishment request step, an end-to-end authentication secret key exchange step and a password update step, which are conducted in sequence. A common session key can be established for two mobile terminals in two different trust domains while the identities of the mobile terminals are verified, so end-to-end secure communication is achieved. On the basis of symmetric encryption and the design of a Hash function, public key password operation that is time consuming is not used, so the method completely meets application demands of limited resources of the mobile terminals in a space-sky information network. The calculating cost of a server is low, and congestion will not occur due to frequent requests of the mobile terminals. Moreover, a dual-factor authentication mode of both an intelligent card and a password is adopted, so higher security is exhibited. Identity information of the mobile terminals is hidden in public information, so the mobile terminals are anonymous in identity.

Description

【Technical field】 [0001] The invention belongs to the technical field of communication, and in particular relates to an end-to-end authentication key exchange method for a heterogeneous network facing an aerospace information network. 【Background technique】 [0002] Space-Sky Information Network (Space-Sky Information Network) is an integrated large-capacity information network that integrates various satellites in the space-based network, various aircraft in the space-based network, and ground communication systems in the ground-based network. The aerospace information network can realize the secure communication of various entities in the aerospace network and the rapid acquisition, high-speed transmission and safe processing of information. The aerospace information network aims at maximizing the benefits of information resources, and has the advantages of large coverage, strong invulnerability, and strong service capabilities. has been widely used. [0003] With the ra...
