Increasing data security in enterprise applications by using formatting, checksums, and encryption to detect tampering of a data buffer

A computer system for using formatting, checksums, and encryption to detect tampering of a data buffer, comprising:

• a computer processor to execute a set of program code instructions;
• and
• a memory to hold the program code instructions, in which the program code instructions comprises program code to perform,
• receiving an unencrypted sequence to be encrypted and stored;
• selecting a layout version, the layout version comprising a layout version identifier to associate at least an encryption method and a checksum method;
• encrypting the unencrypted sequence using the encryption method to form an encrypted sequence;
• and
• storing the encrypted sequence and the unencrypted sequence checksum formed by the checksum method to form a hidden buffer payload
• wherein the layout version identifier identifies a layout arrangement of the hidden buffer payload.

A computer program product embodied in a non-transitory computer readable medium, the computer readable medium having stored thereon a sequence of instructions which, when executed by a processor causes the processor to execute a method to implement using formatting, checksums, and encryption to detect tampering of a data buffer, the method comprising:

• receiving, by a computer, an unencrypted sequence to be encrypted and stored;
• selecting a layout version, the layout version comprising a layout version identifier to associate at least an encryption method and a checksum method;
• encrypting the unencrypted sequence using the encryption method to form an encrypted sequence;
• and
• storing the encrypted sequence and the unencrypted sequence checksum formed by the checksum method to form a hidden buffer payload
• wherein the layout version identifier identifies a layout arrangement of the hidden buffer payload.

A computer implemented method for using formatting, checksums, and encryption to detect tampering of a data buffer, the method comprising:

• receiving, by a computer, the data buffer comprising at least a layout version identifier, the layout version identifier to identify the layout arrangement of a hidden buffer payload;
• using the layout version identifier to associate at least a decryption method and a checksum method;
• decrypting the hidden buffer payload using the decryption method to form an unencrypted sequence and a received unencrypted sequence checksum;
• calculating a calculated unencrypted sequence checksum using the checksum method;
• and
• storing the unencrypted sequence and the calculated unencrypted sequence checksum.
