Abstract
ABSTRACT
The traditional grid faces many problems and has been overcome by the trend to the smart grid. Smart grid is characterized by being two-way network, unlike the traditional one-way network that makes it difficult for the customer to get the amount of power that suits him. In smart grid, the customer has become part of the grid which allows him to request the right amount of energy, as well as to control energy consumption especially at peak times. Smart grid is a major communication revolution that has succeeded in overcoming traditional network problems. However, smart grid components may face many security challenges that make the smart grid vulnerable to various types of attacks.
Due to the nature of the wireless connection, some problems appeared in the smart grid that threatens its security, and from here the plans began to find solutions that maintain the security and efficiency of the network. Therefore, the scholars have presented many plans to solve the problems facing the smart grid, and they have succeeded in achieving mutual authentication between the different entities in the smart grid; however, some of these schemes failed to achieve forward secrecy, anonymity, untraceability as well as resilience to some attackers such as impersonation attack and replay attack, in addition to high computational cost.
To cope with these challenging problems, we propose a lightweight authenticated key establishment scheme depending on data aggregation by using elliptic curve cryptography to
create shared keys between smart meter and data aggregator, and between data aggregator and service provider. The data aggregator reduces the burden on smart meters and transfers consumption data safely as it is the mediator between the smart meter and the service provider. The proposed scheme can provide mutual authentication, anonymity and untraceability of smart meter, and can resist impersonation and replay attacks. In addition, the proposed scheme reduces the overall computation costs compared to other recent related schemes.
