Digital Forensics Security for Communications Transmission by Encrypting and Decrypting Characteristics with One-Time Key Authorization

Abstract

Information can be secretly coded to conceal its actual meaning through the process of encryption. In computers, encrypted data is referred to as ciphertext and unencrypted data is also called plaintext. Data encryption guards against data loss, alteration, and compromise. However, the decryption key needs to be kept private and shielded from unwanted access in order to guarantee that data is kept safe. In this study, the One-Time Key Authorization (OTKA-AED) framework is built to guarantee that message exchange is safe between owners and requesters of cloud data. Additionally, it obtains the OTKA-AED framework that obtains the encryption and decryption method for every session number based on the bilinear mapping transformation and reverse bilinear mapping transformation. In this study, to provide the public key and secret key, the OTKA-AED framework first used the one-time key generation function. This reduced the key generation time and hence, increased cloud security. Finally, permission tag-based encryption and decryption was carried out under the authorization tag, which ensured authorization by effectively reducing communication and storage overhead. The proposed One-Time Key Authorization (OTKA-AED) architecture further ensures message processing within the cloud environment by increasing the security of message communication by encrypting key attributes shared among cloud users.
