Trust Execution Environments

Architecture

Trusted Execution Environments represent secure, isolated hardware-based enclaves within a processor that protect sensitive code and data from external access or manipulation. These environments leverage features like Intel SGX or ARM TrustZone to ensure that the execution of cryptographic operations remains shielded even from the host operating system. By establishing a root of trust at the hardware layer, they provide a high degree of confidentiality and integrity for complex financial applications.
