This method enhances data encryption through white-box cryptography and addresses memory inspection attacks while ensuring forward secrecy.
Abstract This paper presents a novel method for secure key generation and data encryption in hostile environments using a white-box cryptography framework built on time-bound versioned lookup tables (WB-VLUT). Encryption keys are never stored in memory; instead, they are dynamically generated from LUTs using random indexes and metadata appended to the ciphertext. Each key is destroyed after use, and ciphertext carries the LUT version and key index to allow key regeneration for decryption. The approach enables forward secrecy, mitigates memory inspection attacks, and provides practical performance for applications such as DRM and IoT.
