A one-to-many authentication and key agreement scheme based on the sliding window

As an important application of the Internet of Things, the information security of the distributed photovoltaic system is of great importance for economic and social development. However, in recent years, cybersecurity incidents have occurred frequently. To enhance the efficiency and security of the photovoltaic systems, we propose a one-to-many authentication and key agreement scheme based on the sliding window. In this proposed scheme, we adopted lightweight operations such as cascading, XOR and hashing to reduce the storage and computational overhead, rendering it more suitable for the resource-constrained scenarios. Performance analysis and experiments demonstrate that the scheme exhibits advantages in both one-to-one and one-to-many circumstances, rendering it suitable for the photovoltaic system.
