The first task of this thesis is to analyze the security requirements of communications link which is the important branch of the onboard network,study the layers of protocol distribution,put forward the security services and mechanisms for each layer,analyze the communications process of the onboard network,point out the requisite security services for the sensitive parts of the communications link based on its security requirements,give a security scheme of the protocol,and give the schemes to the upper layer and the data package respectively.Meanwhile,we take a series of measures to reduce the space overhead as more as possible.Finally we take the space transport protocol as an example to implement the security scheme of the communications protocol.
