Latest Patents

Chengpeng Li holds a patent titled "Access control policy analysis in a multi-provider network environment." This patent introduces techniques for analyzing access control policies across multiple provider networks. The methods compile various policies into a unified policy language that is broad enough to encompass diverse policy features while being specific enough for automated analysis. An automated differential testing method is employed to confirm the accuracy of this compilation by generating access requests, ensuring that both original and translated policies consistently grant or deny access. Additionally, an abstraction technique is utilized to simplify and correlate the complex details of different policies, enabling easier user inquiries about them. For instance, users can determine if an account has write access in one network but not in another. This abstraction sometimes involves replacing actions in original policies to ensure their compatibility in the target policy language.
