摘要：The paper aims in providing a securely communicating of data between the devices which are nothing but appliance of Home Area Network (HAN) by a set of controller outside the HAN. The packets generated by the controller should be delivered fast without any interruption. The role of an HAN controller is like a gateway, whose role is to filter the incoming packet. Due to this HAN controller, the data in the packets should not be modified & it should not cause any delay in encryption & decryption of the packets. Based on the level of security and quality of service, we design the protocol with an Elliptic Curve Cryptography (ECC) approach. Password Authenticated Key Exchange (PAKE) protocol is improved & implemented. This consists of two phases. We propose an ECC version of PAKE & later extend this protocol to a multilayer consensus ECC based Password Authenticated Key Exchange (PAKE) protocol for smart grid. This protocol uses only one hash function & it utilizes a primitive password between the appliance and HAN controller. The four layer individual consensus passwordauthenticated symmetric key established between the appliance and upstream controllers during only 12 packets.It provides high security level with small key size when compared to RSA algorithm key size which is big with comparison to our proposed protocol. Proposed protocol is resistant against many attacks. It improves & reduces the delay caused by the security process by more than one half. Finally we show that our approach decreases the number of packets & improves the security in smart grid
