Re-encryption of data using distributed subtasks
The patent US12045662B2 describes a non-transitory machine-readable medium and a method for re-encrypting data associated with an application. The process begins with receiving a request to re-encrypt a set of data that has been encrypted with a first encryption key, using a second encryption key. The system determines the amount of work required for the task, which includes the volume of data to be re-encrypted. It then divides this task into subtasks based on the data amount and assigns each subtask to different nodes within a network of nodes configured to execute the application. This structured approach aims to enhance efficiency in the re-encryption process.
Further claims detail the execution of subtasks, which involve retrieving specific subsets of data from storage, decrypting them with the first encryption key, and then re-encrypting them with the second key before storing the newly encrypted data back in the storage system. The method also incorporates retrieving configuration data that includes metadata about the encrypted data, which aids in determining the workload. Additionally, the task can be divided into batches, with each batch corresponding to specific rows in a database or files in a file system, facilitating organized and efficient data handling during the re-encryption process.
