Secure Network Slicing Scheme with Signature Authentication and User Trust

With the development of the slicing network, slicing service providers need to protect the needs of users for differentiated services and they prefer to provide public APIs to users. However, attacks against public APIs pose challenges to the security of user identity authentication. In this paper, we design a network slicing scheme based on signature authentication and user trust, which provides a standardized and unified security access method through RESTful API. It can make access decisions according to the relevant attributes of users. Besides, we proposed a flexible model for the slicing network, featured by user trust and a decision model. The experiment shows that the scheme can ensure the anti-tampering and anti-counterfeiting of the slicing scheme, prevent replay attacks, enhance the non-repudiation of information and enhance the access judgment ability of the slicing scheme.
