Abstract
This paper presents an efficient, secure audio file encryption technique that balances speed and complexity for social media audio applications. The proposed technique is adapted from the Advanced Encryption Standard (AES) to eliminate the corresponding time cost. In particular, MixColumn is replaced by a fifth-order magic square in GF (2^8) irreducible polynomial to achieve two levels of key encryption. The magic square's first level of security is provided by a 9-cell-long key generated by a Random Number Generator (RNG), which provides good obfuscation. The second level of key encryption is executed using a 6D chaotic system, providing efficient propagation. The 16-cell voice messages generated in the first round will be considered as input for subsequent rounds. The proposed approach provides robust security against brute force attacks owing to the extensive key space GF (25618) r+1, where r is the total number of rounds. The temporal complexity and encryption quality are assessed per NIST standards, and the peak signal-to-noise ratio of differential assaults is computed. In comparison to the conventional AES method, the findings indicate that the fifth-order magic square demonstrates comparatively enhanced performance regarding time and complexity.
