Comprehensive and Comparative Analysis of Different Files Using CP-ABE

Abstract

In a business organization, the data needs to be shared among different personnel, therefore chances of fraud are more. In order to protect the organization’s confidential and sensitive data among different levels of employees from theft or any other illegal activity that violates the company security policy, ABE known as Attribute-Based Encryption was introduced. ABE is a cryptographic parameter that plays a vital role in providing fine-grained access control of outsourcing data in data sharing system of the business organization but due to its non-efficiency and several other limitations, it was proved inefficient in outsourcing of data. However, Cipher-text Policy Attribute-Based Encryption (CP-ABE) was implemented to overcome the existing ABE issues and to protect the firm’s confidential data from theft or leakage. CP-ABE defines an access policy that covers all the attributes within the system. In this scheme, the user’s private key is associated with the set of attributes for encryption and decryption purposes. Our experimental simulations demonstrate the real encryption/decryption time over different types of files and their sizes and how they get affected after applying CP-ABE. The performance and security analysis stipulated that the used scheme is competent to securely manage the data in any organization.
