Comment on "Improved RSA Technique with Efficient Data Integrity Verification for Outsourcing Database in Cloud".

In 2022, Neela and Kavitha proposed an improved RSA encryption algorithm (IREA) for cloud environment. In this paper, we review and comment on the correctness of the IREA technique. We prove that the private key generation in the proposed IREA is mathematical incorrect. That is, decryption of the cipher generated by the public key is not possible with the private key. Further, we discuss the possible modifications in IREA to make it correct decryption.
