Abstract |
|
|
| The electric power network that used to run as a closed circuit is operated in connection
with various wired and wireless networks in the smart grid environment. Thus the security threats in
the existing communication environment and additional threats from the characteristics of the smart
grid are expected. Therefore, it is critically required to develop of the security mechanism to establish
a secure smart grid environment from these threats. In this paper, we propose a mechanism that
provides mutual authentication and session key establishment between the smart meter and DCU.
The proposed mechanism has advantages in preventing attackers to transmit information,
impersonating a smart meter or a DCU, providing confidentiality and integrity to transmitted
messages by generating a new key in each session, and management efficiency to use only the DCU’s
certificate.
