Adaptive Attribute-Based Encryption on Blockchain with Enhanced Authentication Mechanism

Abstract

Authentication is an essential component of a system since it serves in many circumstances as both the first and the last line of protection. Authentication makes it possible to stop users who are not approved from accessing the system.  A novel Adaptve Attribute Based Encrytion (ABE) encryption using Threshold ABE, Multi Factor Authentication (MFA) and Revocation mechanism is utilized to add a layer of security to the authentication process as part of this plan. Proposed ABE encryption has been used to add a layer of security to the authentication process. Further, the simulation results of the proposed ABE are compared with ABE & Rivest Cipher 4 (RC4) in terms of cost of execution & transaction packet delivery rate & packet loss rate, and encryption & decryption execution.
