Innovative Security Framework for Enhancing Data Protection in Mobile Cloud Environments

Abstract: There is especially a challenging problem for secure communications in the last few years among the resource-poor environments like IoT devices and embedded systems which had driven the research to lightweight cryptography algorithms, performing wonderfully on the constraints of computations, memory, as well as also energy resources. It involves the implementation along with performance analysis of probably the most impressive lightweight block ciphers, such as SIMON, SPECK, and HIGHT. It also encompasses ECC as a safe alternative substitute to the traditional ones that contain AES. SIMON and SPECK are new-generation lightweight block ciphers developed by NSA for hardware efficiency so that performance is maximized at low speeds with very high levels of security. Also included are the performance characteristics of HIGHT, which is a specially designed block cipher for environments with very low resources. ECC is presented as the asymmetric encryption algorithm that provides at least some level of security yet its key sizes are dramatically smaller than the counterparts making it well applicable within these environments. In addition, an overall comparison in the aspect of the computational cost, usage of the memory, and the security level among the algorithms is made
