In smart grid, how to establish a communication paradigm among the customers, smart meter and utilities is an important challenge, which requires access control, data encryption, and authentication to ensure message integrity and confidentiality. In this paper, we present a communication architecture based on Attribute Based Cryptosystem to secure the communications in smart grids. In this paper, we present a communication architecture based on Attribute Based Cryptosystem to secure the communications in smart grids. A user can decrypt a ciphertext if and only if it possesses the attributes required by the access structure of the data. |
