A Model for Data Confidentiality and Integrity during Replication in Fog & Edge Computing Environment

In the study of confidentiality and integrity during replication in fog and edge computing environments, the SHA256 hashing algorithm and the PyCryptodome library played crucial roles. The SHA-256 algorithm, a member of the SHA2 family, was employed for its robust cryptographic hash function, ensuring data integrity by generating a unique, fixed-size 256-bit hash value for every input. This characteristic was pivotal in detecting any alterations to the data, thereby preserving its integrity during transmission and storage. The PyCryptodome library, an extensive suite of cryptographic functions, was utilized to implement the SHA-256 algorithm effectively. This library provided the necessary tools to integrate advanced cryptographic techniques into the system, enhancing the security of data replication processes. By leveraging these technologies, the study aimed to establish a secure framework that safeguarded data confidentiality and integrity across distributed fog and edge computing environments. The results demonstrated the feasibility and efficacy of using SHA-256 and PyCryptodome in mitigating potential security threats, thereby contributing to the development of more resilient and trustworthy computing infrastructures. Object-Oriented Development (OOD) is employed to decrease development schedules, reduce resource demands, and improve code reusability. Python serves as the programming language, while MySQL functions as the database.
