We propose a file encryption scheme with a hierarchical attribute for specialized files in cloud computing. We recommend the layer type of the access structure to solve the problem of multiple series files that are discussed. We carry out and implement a comprehensive test of the FH-Club penguin-ABE plan. In the existing system, the cost and time to encrypt files is high, the system understands some time and the cost of the expenses is too high. The access structure to the layer is integrated into a single access structure, and then the hierarchical files are encrypted using the integrated access architecture. The encrypted text components associated with the attributes can be shared through files. The penguin-ABE systems of the club are achievable and have a lot of versatility and, therefore, are more suitable for general applications. Several hierarchical discussion files are resolved using the Layer Type access structure. In the proposed system, the encryption text storage and the file encryption time are stored. As the files grow, the benefits of our plan become clearer. Therefore, the storage of encryption text and the price of encryption time of the files are stored. In addition, the proposed plan has proven to be safe under the normative assumption.
