Research issues related to cryptography algorithms and key generation for smart grid: A survey

With advent of technology existing electrical grids are changed to smart grids which are effective power management, secure communication, reduced production cost and environment friendly. But, Smart Grid is complex hierarchy architecture. There are various stakeholders included. So, the biggest challenges are authentication and authorization. Secondly how to secure the communication lines from various cyber attacks. In this paper, a survey is done on various cryptography algorithms and related key generation for smart grid application. On the basis of survey several research issue have been discussed for the secure operations in the smart grids. It has been found that lightweight algorithms are more suitable in smart meters because of less area and memory required. Key generation for cryptography algorithm should be generated from noise and jitter as a seed because of their random nature to prevent from cyber attacks.
