Discover Trusted Computing and its role in protecting data during processing. Thanks to the Trusted Execution Environment (TEE), this technology ensures the confidentiality and integrity of data and code, while eliminating the risks associated with trusted third parties such as the OS or administrators.
Trusted computing is an approach designed to protect data during processing. It is based on the execution of code in a secure enclave known as the Trusted Execution Environment (TEE).
This enclave guarantees the confidentiality and integrity of data, as well as the security of code during execution. In concrete terms, this means that only authorized entities can access, modify or delete data. In addition, code integrity is ensured, preventing any unauthorized modification.
Confidential computing also supports additional processes such as TEE certification and migration of workloads between several TEEs.
Although enclaves can be hardware- or virtualization-based, the Confidential Computing Consortium focuses specifically on hardware-based TEEs. This choice is based on the desire to guarantee an optimum level of security, acting directly at silicon level to avoid any vulnerability in the underlying layers.
So, with a secure environment at hardware level, it becomes possible to remove trusted third parties such as the OS, drivers or administrators, ensuring enhanced data protection.
