Abstract
Objective: Smart grid is an evolved grid with smart features. The smart grid is responsible for the uninterrupted flow of energy and transmission of data generated by the stakeholders. The versatility and integrity of the entire network completely rely on the protection of data which is generated by the smart meters. These smart meters are deployed at the user’s end. By various possible attacks, smart communication network can be hijacked. Also, existing security approaches are not sufficient for handling the generated enormous amount of data. These issues facilitate the need to work on designing a security algorithm that provides better security and better efficiency in smart meter communication.
Methods: This paper presents a proposed model with enhanced security that not only encrypts enormous amount of data but also does it in a very little time. The proposed algorithm is based on a bi-key computational algorithm where two different entities are used as keys. With the use of this algorithm, breaking the originality of message becomes NP Hard problem.
Results: The proposed method has been analyzed with the existing cryptographic algorithm and this method has shown promising results.
Conclusion: This paper presents a method. The working of the method is simulated in Matlab. The obtained results confirm the adaptability and acceptability of the proposed method for the enormous data.
Keywords: GCD, network security, smart meter, grid, data transmission, security, AES, DES.
