Cloud computing empowers clients to eliminate the need of the need of neighborhood equipment design, which eliminates the weight of the clients from high calculation costs. Along these lines, it has pulled in much consideration and examination has been led intensely on it. To ensure clients' security, information is generally encoded before being shipped off the cloud worker. As the subsequent framework is unusable, since the cloud can at this point don't look all through the information, new cryptographic crude, for example, public-key encryption with correspondence test (PKEET) has been presented. In PKEET, clients can test whether the hidden messages of two code messages encoded under various public keys are equivalent or not without the need to decode those ciphertexts. This is a valuable device, particularly for the cloud data set, since PKEET chiefly centers around the equity test between two ciphertexts. Nonetheless, practically speaking, the cloud worker may have to check the equality among more than two ciphertexts. This prompts unveiling pointless data of clients and repetitive calculation cost will likewise happen when utilizing conventional PKEET plans. Instructions to make this more proficient and down to earth stays an interest search issue. In this paper, to take care of the previously mentioned issues by giving a novel idea of public-key encryption with multi-ciphertext correspondence test (PKE-MET). In PKE-MET, each ciphertext can assign a number s to such an extent that the cloud worker can just perform equity test on this ciphertext with other s − 1 ciphertexts, where all their assigned numbers are s. For PKE-MET, other than customary OW-CPA and IND-CPA security, we extraordinarily characterize Number security. We launch PKE-MET to a solid plan and give its security verification. Moreover, to empower the crude to be more useful in applications, we extend it to the idea of PKE with adaptable MET (PKE-FMET). In PKE-FMET, the cloud worker can perform fairness test on quite a few ciphertexts as long as the most extreme number of their assigned numbers is not exactly or equivalent to the quantity of ciphertexts. We build a PKE-FMET plot dependent on our PKE-MET development and demonstrate its security under the characterized security models. Also, the exhibition examination predominantly of productivity and security between our developments and existing fairness test plans in Cloud computing show that our proposed plans are more effective and secure in the multi-ciphertext situation.
