Embodiment Construction

[0053] The implementation manner of the trusted security access method will be described in detail below with reference to the accompanying drawings.

[0054] Description of the main cryptography knowledge, trusted computing technology and security assumptions used in this method:

[0055] 1. Bilinear pairing: let G 1 , G 2 They are respectively the additive cyclic group and the multiplicative cyclic group whose prime number is q in the elliptic curve, and P is the group G 1 the generator of G , and G 1 The discrete logarithm problem on is intractable. Then the bilinear map e:G between two groups 1 ×G 1 →G 2 satisfy the following properties.

[0056] (1) Bilinearity: e(aP,bQ)=e(P,Q) ab , for all P,Q∈G 1 ;a, b∈Z are all established;

[0057] (2) Non-degenerate: there is P, Q∈G 1 , making e(P,Q)≠1;

[0058] (3) Computability: For P, Q∈G1 , there exist efficient algorithms to compute e(P,Q).

[0059] 2. PCR is the value of some registers in the TPM chip that represen...

Abstract

A trusted and secure access method for aerospace information network roaming, including five stages: node registration stage; request access stage; identity authentication stage; integrity verification stage; key generation stage; terminal access node MN and foreign security The domain authentication server FA completes the negotiation of the session key. At this time, the process of the entire aerospace information network roaming trusted security access method is completed, and the mutual identity authentication between the terminal access node MN and the foreign security domain authentication server FA is realized. and integrity measurement, and realize the session key exchange between the terminal access node MN and the foreign security domain authentication server FA involving the terminal access node MN, the foreign security domain authentication server FA, and the local domain security domain authentication server HA. negotiate. It has fewer interaction rounds, high session key security, uses trusted computing related technologies, and realizes the integrity measurement of terminal access points, and solves the attack on the network that is prone to occur due to terminal integrity and credibility. .

Description

technical field [0001] The present invention provides a trusted and secure access method for aerospace information network roaming, which relates to a trusted and secure network access method for terminal nodes in an aerospace information network environment. The method introduces the concept of trusted computing into the space In the Sky Information Network, the integrity measurement and trusted authentication of the terminal are realized, which belongs to the field of security access technology. Background technique [0002] Space Information Network (SIN) is a comprehensive information system based on satellite systems for navigation, communication, information support and security. Spacecraft (such as satellites, space shuttles, etc.), aircraft (such as airplanes, hot air balloons, etc.) and ground station systems with space communication capabilities are linked. like figure 1 shown. At the same time, the security issues caused by the openness of SIN transmission have...
