Confidential Computing Zoo (CCZoo) is a collection of code-ready reference solutions, which can be used as a copy-paste developer guide, demonstrating how to apply modern security technologies to real-life cloud business scenarios, in order to facilitate the developers to build their own end-to-end Confidential Computing solutions more easily. Some of the solutions are also validated on the public cloud services, such as Alibaba Cloud, AWS, Azure, etc.

The concerned modern security technologies are (but not limited to): TEE (Trusted Execution Environment, such as Intel® SGX and TDX), HE (Homomorphic Encryption) and its hardware accelerations, Remote Attestation, LibOS, cryptographic and its hardware accelerations. The concerned business scenarios are (but not limited to): cloud native AI inference, vertical and horizontal federated learning, big data analytics, key management, RPC (Remote Process Call, such as gRPC), etc.

CCZoo maintains a live table, as below, to indicate the correlations between business usages (rows) and security technologies (columns). Each hyperlink will direct you to the document section that explains the corresponding details and then guides you to the source codes. Enjoy!
