  • Safeguarding cryptographic keys from modification or deletion
    Patent number: 11652626
    Abstract: Aspects of the invention include generating a cryptographic key to restrict access to a resource. The cryptographic key being defined by a key token. An exemplary method includes designating a storage field in metadata of the key token, in metadata of a cryptographic key data set record that includes the key token, or in a resource access control database that controls use of the cryptographic key for inclusion of an indicator that the cryptographic key may or may not be deleted or modified. The indicator in the designated storage field is set to indicate whether or not the cryptographic key may be deleted or modified.
    Type: Grant

  • System generated data set encryption key
    Patent number: 11277262
    Abstract: Generating unique data encryption keys for a data set, by allocating a data set associated with a security policy, where the security policy specifies a key encryption key (KEK) label, retrieving the KEK label from the security policy, storing the KEK label as metadata of the data set, opening the data set for a first time write, generating a data encryption key (DEK), retrieving a KEK from a key store according to the KEK label, encrypting the DEK using the KEK, storing the encrypted DEK as metadata of the data set, and encrypting the data set using the DEK.
    Type: Grant
