Trust and reputation approach to smart grid security

The electric grid in the US is aging and needs to be upgraded. Solutions involve the use of equipment with wireless communication capability for monitoring of generation, transmission and distribution. These systems introduce vulnerabilities to attack that can lead to blackouts and damage to equipment. In order to increase the reliability of the power systems, it is important to detect sources of risk at the system and individual level. The approach described in this paper applies trust and reputation management at the home based meter to detect when false reports occur.
