SM9 Key Encapsulation Mechanism for Power Monitoring Systems

The boundaries of the new power system network are blurred, and data privacy and security are threatened. Although the SM9 algorithm is widely used in power systems to protect data security, its efficiency and security remain the main issues in application. Therefore, an SM9 key encapsulation mechanism (OSM9-KEM-CRF) was proposed to support outsourced decryption and cryptographic reverse firewall. In order to resist the backdoor attacks, we deployed cryptographic reverse firewalls at the terminals and proved that the proposed OSM9-KEM-CRF is ID-IND-CCA2 secure. The cryptographic reverse firewalls maintain functionality, weakly retain security, and weakly resist penetration, thereby enhancing the security of the scheme. In addition, considering the limited computing resources of terminal devices, decryption operations are outsourced to cloud servers in order to reduce the computational burden on the terminals. Compared with other SM9-KEMs, the proposed mechanism not only reduces computational and communication overhead, but also lowers energy consumption. Therefore, the proposed mechanism is more suitable for power monitoring systems.
