For the future of the Internet, because information-centric network (ICN) have natural advantages in terms of content distribution, mobility, and security, it is regarded as a potential solution, or even the key, to solve many current problems. Named Data Network (NDN) is one of the research projects initiated by the United States for network architecture. NDN is a more popular project than ICN. The information cache in the NDN separates content from content publishers, but content security is threatened because of the lack of security controls. Therefore, a multi-authority revocable access control method based on CP-ABE needs to be proposed. This method constructs a proxy-assisted access control scheme, which can implement effective data access control in NDN networks, and the scheme has high security. Because of the partial decryption on the NDN node, the decryption burden of the consumer client in the solution is reduced, and effective user and attribute revocation is achieved, and forward security and backward security are ensured, and collusion attacks are prevented. Finally, through the other security and performance analysis of the scheme of this paper, it proves that the scheme is safe and efficient.
