With the advancement of Technology, the existing electric grids are shifting towards smart grid. The smart grids are meant to be effective in power management, secure and safe in communication and more importantly, it is favourable to the environment. The smart grid is having huge architecture it includes various stakeholders that encounter challenges in the name of authorisation and authentication. The smart grid has another important issue to deal with that is securing the communication from varieties of cyber-attacks. In this paper, we first discussed about the challenges in the smart grid data communication and later we surveyed the existing cryptographic algorithm and presented comparative work on certain factors for existing working cryptographic algorithms This work gives insight conclusion to improve the working scheme for data security and Privacy preservation of customer who is one of the stack holders. Finally, with the comparative work, we suggest a direction of future work on improvement of working algorithms for secure and safe data communication in a smart grid.
