Bhandari and K. V. B. proposed an encryption model that combines both symmetric and asymmetric algorithms, suggesting secure data transmission using the Advanced Encryption Standard (AES). Meanwhile, Subasini and Raju introduced a lightweight encryption algorithm by combining ECC with identity-based encryption. However, conventional key exchange methods like ECC demand high computational power. Therefore, we propose a simple key exchange method that utilizes commonly shared data in advance, tailored for transmitting encrypted data in IoT environments.
