US Patent 12130704 Encoding and encrypting data in a storage network

A storage network operates by: receiving a encoded data slice for storage by the storage network, wherein the encoded data slice is associated with a vault; generating a encryption key corresponding to the encoded data slice based on a vault identifier associated with the vault; utilizing the encryption key to generate a encrypted data slice and that corresponds to, and is based on, the encoded data slice; storing the encrypted data slice in a storage unit of the storage network; receiving a request to retrieve the encoded data slice; retrieving the encrypted data slice corresponding to the encoded data slice from the storage unit of the storage network; generating a decryption key corresponding to the encoded data slice based on the vault identifier, wherein the decryption key is different from the encryption key; and regenerating the encoded data slice using the decryption key.
