  • System and method for managing cryptographic keys
    Patent number: 9490973
    Abstract: In various implementations, a first device retrieves, from a memory, encrypted data encrypted using a first key. The first device transmits, to a second device, a request for an encrypted first key, where the encrypted first key is generated by encrypting the first key using a second key. The first device receives the encrypted first key. The first device transmits, to an identity and access management device (IAM), a request for an encrypted second key, where the encrypted second key is generated by encrypting the second key using a third key. The first device receives the encrypted second key. The first device decrypts the encrypted second key using the third key, decrypts the encrypted first key using the decrypted second key, and decrypts the encrypted data using the decrypted first key. The first device deletes, from its cache, the decrypted first key after a period of time.
