The advancement of quantum computing poses a significant challenge to future data protection, particularly in IoT environments due to their constrained computing capabilities. Consequently, this research investigated the application of Post-Quantum Cryptography (PQC), which integrates Kyber and Dilithium cryptographic algorithms into a signcryption mechanism to protect data confidentiality and integrity on Raspberry Pi 4, a device employed as an IoT node gateway in smart home applications. The KyberDilithium cryptographic system employed in this study was compared with the classic cryptography RSA 2048 and secp256r1. The research conducted indicates that Kyber512-Dilithium2 Signcryption can be implemented on Raspberry Pi 4 as an IoT node gateway. Kyber512Dilithium2 exhibits superior CPU utilization compared to RSA 2048 and secp256r1 across all processes which used 98.483% for key generation, 93.722% for signcrypt, and 93.591% for unsigncrypt. This indicates that the Kyber512-Dilithium2 could be used in IoT node gateways to ensure robust data security in smart home environments against future quantum attacks by combining PQC of Kyber and Dilithium into signcryption.
