In this concepts section, we will describe the key concepts that are at the core of BlindLlama. Each section contains an introduction to the concept itself followed by a discussion of how we use these technologies in BlindLlama.

The concepts we will cover are:

  • Hardened systems: We describe how we use hardened systems to eliminate data exposure, even to our admins
  • Trusted Computing Base (TCB): We detail which elements of our computing base are trusted or attested
  • Trusted Platform Modules (TPMs): We explain how we use TPMs to provide cryptographic proof that our privacy and security measures are in place
  • Attested TLS: We describe how we combine secure communications with attested hardened environments to provide robust end-to-end data protection and prove we are communicating with our hardened environment
