  This paper is proposed a security plan for Smart Grid Systems based on
AGC4ISR which is an architecture for Autonomic Grid Computing Systems. Smart
Grid incorporates has many benefits of distributed computing and communications
to deliver a real-time information and enable the near-instantaneous balance of
supply and demand at the device level. AGC4ISR architecture is Organized by
Autonomic Grid Computing and C4ISR (Command, Control, Communications, Computers
and Intelligence, Surveillance, & Reconnaissance) Architecture. In this paper
we will present a solution for as security plan which will be consider
encryption, intrusion detection, key management and detail of cyber security in
Smart Grids. In this paper we use the cryptography for the packet in the C4ISR
and we use a key management for send and receive a packet in the smart grid
because it is necessary for intelligent networks to keeping away from packet
missing.
