Inside PSL: Key Management, Sandboxing, and Secure Enclaves Explained

This article explores how PSL leverages SCL to securely execute workloads inside enclaves, using sandboxed JavaScript for isolation, attestation protocols for trust, and hierarchical deterministic (HD) wallet-style key management for scalable cryptographic control. With enclaves handling runtime environments, PSL ensures keys are uniquely derived, rotated efficiently, and protected against leakage. The result: a secure, flexible framework for serverless computing that reduces the trusted computing base while enabling scalable, encrypted, and verified workloads.
