Abstract
An encrypted file system key associated with a first secure enclave may be received. A request from a second secure enclave to access a file system associated with the encrypted file system key may be received. In response to receiving the request, the encrypted file system key may be decrypted with a cryptographic key associated with an enclave manager to obtain a file system key. The file system key may be encrypted based on another cryptographic key associated with the second secure enclave to generate a re-encrypted file system key. Furthermore, the re-encrypted file system key may be provided to the second secure enclave.
