The Spark big data analysis program jointly developed by Ant Group and Intel was launched for the first time

By using the Spark in Occlum capability, existing Spark applications can directly run in the TEE environment without any code modification, and can be expanded horizontally according to the data size, easily supporting the data size of TB. On the other hand, remote proclamations for integrity are also added to the process without notice. Application developers do not need to explicitly add remote proclamations. Remote proclamations provided by Occlum and BigDL enable remote proclamations and validations of instances. The solution is available on the Microsoft Azure Confidential Computing blog and is open source.

With the development of the current TEE hardware architecture, in order to meet more security requirements in different computing scenarios, Occlum supports GPU TEE, extending the TEE security capability provided by the CPU to the GPU, ensuring that data can be securely transferred to more powerful computing hardware devices.

Occlum is also gearing up for Intel's next-generation TEE TDX next year. Occlum plans to evolve from user-oriented to kernel-oriented operating systems.
