Advanced Metering Infrastructure forms a communication network for the collection of power data from smart meters in Smart Grid. As the communication between smart meters could be secured utilizing public-key cryptography, however, public-key cryptography still has certain challenges in terms of certificate revocation and management particularly related distribution and storage overhead of revoked certificates. To address this challenge, in this paper, we propose a novel revocation management approach by utilizing cryptographic accumulators which reduces the space requirements for revocation information significantly and thus enables efficient distribution of such information to all smart meters. We implemented the proposed approach on both ns-3 network simulator and a testbed. We demonstrated its superior performance with respect to traditional methods for revocation management.

适用于高级计量基础设施和物联网集成的通信高效证书吊销管理

高级计量基础设施形成了一个通信网络，用于从智能电网中的智能电表收集电力数据。然而，由于智能电表之间的通信可以利用公钥加密技术来保证安全，因此公钥加密技术在证书撤销和管理方面仍然存在一定的挑战，特别是与撤销证书的分发和存储开销相关的挑战。为了应对这一挑战，在本文中，我们提出了一种利用加密累加器的新型吊销管理方法，该方法显着减少了吊销信息的空间需求，从而能够将此类信息有效地分发到所有智能电表。我们在 ns-3 网络模拟器和测试平台上实现了所提出的方法。我们展示了其相对于传统撤销管理方法的卓越性能。
