Systems and methods are provided for data access protection. The disclosed computing system can provide an adjusted iteration count to a dynamic key stretching module. The computer system can determine whether the adjusted iteration count is to be used to enhance a passphrase for data encryption or data decryption. When the adjusted iteration count is to be used for data encryption, the computing system is configured to compute the adjusted iteration count by modifying a base iteration count according to an adjustment configuration; when the adjusted iteration count is to be used for data decryption, the computing system is configured to retrieve the adjusted iteration count that was used to encrypt the data. Once the adjusted iteration count is determined, the computing system is configured to provide the adjusted iteration count to the dynamic key stretching module. |
