Highly secure WAIC baseband signal transmission with byte displacement approach

An encryption/decryption method implemented by a transceiver baseband hardware, the encryption/decryption method comprising:

• utilizing a random key address to select a key coefficient stored on an on-chip memory of the transceiver baseband hardware;
• applying a cross logical operation utilizing the key coefficient to encrypt intended transmission data or decrypt encrypted data via an encryption-decryption block of the transceiver baseband hardware;
• employing the random key address to jumble the encrypted transmission data or unjumble received jumbled encrypted data via a byte displacement/placement block of the transceiver baseband hardware;
• wherein the cross logical operation comprises lower significant bytes of the key coefficient operating on most significant bytes of the intended transmission data or the encrypted data.
