T/SHCCIA 002-2023 The application requirements for homomorphic encryption technology in cloud computing

Scope

Scope: Homomorphic encryption can achieve that the ciphertext data encrypted with data encryption has similar computing capabilities to the plaintext data, which means that the ciphertext data can be directly used for computing without the need to decrypt it, effectively ensuring the privacy and security of the data during its use. Applying homomorphic encryption technology in the cloud environment allows cloud data to be processed without decrypting it, maximally ensuring the security of enterprise cloud data, and thus achieving the goal of "accessible but invisible, computable but unidentifiable" for cloud data. This document specifies the basic requirements, general security requirements, and performance and accuracy requirements for the application of homomorphic encryption technology in cloud computing scenarios; Main technical content: This document defines the participants and workflow of homomorphic encryption technology applications in cloud computing scenarios, and stipulates the basic requirements, general security requirements, and performance and accuracy requirements for the application. This document is applicable to guiding technology providers of homomorphic encryption in system design and development in the cloud computing scenario, and is also applicable to cloud service providers or third-party evaluation institutions for managing and evaluating the application of homomorphic encryption technology in the cloud computing scenario.
