Cloud computing is a rapidly advancing paradigm that enables users to access various services and resources anytime, anywhere. With this advancement, security has become major concern for business organisations individuals, hence, it essential ensure the are provided with high data security. Numerous researches have focused on devising effective techniques enhance However, increasing connectivity, still remains be challenge. This paper devises novel protection scheme in cloud by using Twofish encryption algorithm key generation Bald Eagle Pelican Optimization (BEPO) Algorithm. The proposed Twofish+BEPO_KeyGen implemented phases, like initialization, registration, generation, encryption, authentication, validation sharing, decryption. Here, used encrypt outsourced cloud, required generated BEPO algorithm. efficacy of approach examined considering metrics, memory usage, time, normalized variance, conditional privacy, detected achieved values 76.3 MB, 37.278 s, 1.665, 0.926, correspondingly.
