Abstract: Message authentication has vital significance for dynamic microgrid partition in smart grid. However, current message authentication protocols based on “public key infrastructure†are too complicated to be deployed in smart grid and lack group information management function. On the other hand, group information management protocols based on “logic key hierarchy†need to broadcast a lot of messages during microgrid partition processes, resulting in high communication costs. To address these issues, we present a novel identity-based message authentication protocol for dynamic microgrid partition called securing dynamic microgrid partition. Similar to the protocols of this field, securing dynamic microgrid partition can provide message authentication and group information management functions. However, compared to other well-known approaches, securing dynamic microgrid partition uses Bloom filter for managing group information, which can reduce the communication cost of logic key hierarchy significantly. Moreover, securing dynamic microgrid partition uses Lagrange interpolation for designing new identity-based signing and verification algorithms, which is simple to be deployed in smart grid environment and much more efficient than current identity-based protocols. Experimental results show that the proposed approach is feasible for real-world applications.
