Confidential Computing

---

Confidential computing is a cloud computing technology that protects data during processing.

• new and emerging focus for organizations operating in extremely secure environments
  • e.g., military and defense sector
• extends security throughout the computing process
• In normal client-server computing model,
  • client may request server to take action on client’s behalf
  • server might have to access some data that is maintained in a separate storage environment, then perform some processing on it
  • to secure this, we apply encryption to data on the storage devices and to network communication
  • but typically do not address data actively processed
• adds protection for data and code in memory with Trusted Execution Environments (TEE)
  • these environments guarantee no outside process can view or alter data being handled within the environment
• adds additional assurance that data is protected throughout all stages of the computing life cycle
