Abstract:
A method for sharing encrypted data and encryption keys through a system comprised of the following data types, but not limited to a; 1) Record and its encryption key, 2) RecordSet and its encryption key, and 3) Entity and its encryption key. A Record is encrypted using an encryption key, furthermore, the Record encryption key is encrypted using a RecordSet encryption key, and finally, both the encrypted Record and its encrypted encryption key are wrapped as a single unit, to avoid key the expensive operations of key lookup and general key operation overhead. Access control to the RecordSet encryption keys are provided by a combination of data types, but not limited to a; 1) Entity and its encryption key, 2) Ciphers, and 3) Trusted Entity Lists. For each Entity which is authorized access to access a RecordSet, an encrypted Cipher, made of both the Entity encryption key and RecordSet encryption key, is added to a Trusted Entity List. Tokens are protected by user defined secrets, comprised of Entity encryption keys.
