发明名称 INCREASING DATA SECURITY IN ENTERPRISE APPLICATIONS BY USING FORMATTING, CHECKSUMS, AND ENCRYPTION TO DETECT TAMPERING OF A DATA BUFFER
摘要 A method, system, and computer program product for using hidden buffer formatting and passing obfuscated encryption key values to detect tampering with and/or prevent unauthorized inspection of a data buffer. The method comprises receiving an unencrypted sequence to be encrypted, selecting a layout version to associate to an encryption method and a checksum method, then encrypting the unencrypted sequence using the encryption method to form an encrypted sequence, and calculating, using the checksum calculation method, an unencrypted sequence checksum. Further, storing the encrypted sequence to form a hidden buffer payload, which hidden buffer has its own hidden buffer payload checksum. Encryption keys are not stored in program data, nor sent in the hidden buffers. Instead obfuscated encryption key values are used to generate keys on the fly. The receiver of a hidden buffer and obfuscated encryption key values can detect tampering or data corruption of the payload for further processing.
