The MEE key is generated at boot, and is placed in special registers, and destroyed at system reset. The MEE key is used for memory encryption and decryption.

The private keys in TEE-assisted systems are extremely crucial but hard to manage. Placing application keys in a single TEE enhances security but creates a single point of failure. Meanwhile, sharing keys among multiple TEEs increases availability but raises the risk of key exfiltration. Key sharing technologies remain complex and inadequate in addressing these challenges, raising concerns about potential attacks that could leverage compromised attestation keys to present false execution confirmations.

Keyo revolutionizes the everyday task of key management by combining functionality and minimal design, allowing users to access their keys effortlessly and elegantly.
