Introduction

Kunpeng cryptographic-computing acceleration library (KCAL) is integrated into the data security suite DataGuard. DataGuard handles the necessary KCAL configuration and calls KCAL APIs to enable multi-party computation (MPC) capability. KCAL has the following features:

• Raw data isolation: It keeps the raw data of users within the secure computing domain using the MPC protocol.
• Operator acceleration: KCAL designs efficient MPC protocol by leveraging the security guarantees of the trusted execution environment (TEE). This allows KCAL to execute operators faster compared to traditional cryptographic MPC protocols.
