The rapid evolution of the Web of Things (WoT) demands cryptography solutions to ensure a high level of security with minimal usage and to work efficiently. In large scale WoT environments, standard cryptographic primaries can be of great energy and computational cost. The following paper is a proposal of a hybrid cryptographic system that will combine the lightweight SPECK block cipher and the Secure Hash Algorithm-3 (SHA-3) to provide improved data integrity, authentication, and efficiency in operations. The proposed hybrid cryptography can reduce the complexity of computing and still have a high level of security since it adds SPECK to the SHA-3 sponge design. Experimental results show significant gains in execution time and throughput compared to SHA3-512, especially for large data sets. Furthermore, NIST Statistical Test Suite findings show that the proposed hybrid approach has randomness properties comparable to SHA3-512, with all p-values exceeding the acceptable significance threshold. These findings show that the suggested hybrid cryptography is a scalable and efficient security solution for resource-constrained WoT.
