Security research of state cryptographic authentication security chip in smart grid

Security chip is widely used in security equipment of power distribution and utilization, ensuring information security of control systems in smart grid. The paper analyzes the threat and protection, such as disturbance attack, side channel attack and data transmission attack, which the state cryptographic authentication security chip are faced with in terminals of power distribution and utilization in smart grid. Then this paper concludes that the security chip achieves the security goal.
