Cloud computing has benefited significantly from the ever-increasing capabilities of computer hardware, including faster microprocessors, larger memory capacity, and greater network bandwidth with high storage. This trend is expected to continue. Cloud computing enables the addition of colored displays to full-blown Web browsers. Some processes add embedded cloud warnings to investigate how data are stored on a local or intermediary system. For instance, all log files of a cloud computing server upload or download data, and all the sessions are stored in clear, unencrypted text on a local computer that multiple users have access to. The cloud client encrypts sessions with the standard method; however, the server does not fully protect such sessions. A high scheme with low-cost encryption and an elliptic curve is established in this study to solve this issue. A lookup table is integrated into the proposed framework.
