CertificateLess Hybrid SignCryption (CL-HSC) scheme is useful for efficiently encapsulating symmetric keys for secure communications. It solves the key escrow problem and the certificate management problem. However, the existing scheme is not suitable for Advanced Metering Infrastructure (AMI) networks because of the utilization of expensive pairing operations. As smart meter devices have limited computing power, we need efficient algorithms for AMI networks. In this poster, we propose a novel CL-HSC scheme without pairing operations. In order to evaluate its performance, we implemented our CL-HSC scheme and conventional hybrid encryption approaches. The experimental results show that our CL-HSC scheme is efficient and suitable for secure communications in AMI networks.
