Dynamic Secret Based Wireless Smart Grid Encryption And Authentication Technique
Smart grid communication has recently received significant attentions to facilitate intelligent and distributed
electric power transmission systems, but also introduces many security problems. In this paper the concept of dynamic secret is
applied to design dynamic secret based authentication and encryption scheme for smart grid wireless communication. Between
two parties of communication, the previous packets are coded as retransmission sequence, where retransmitted packet is
marked as “1” and the other is marked as “0.” During the communication, the retransmission sequence is generated at both sides
to update the dynamic encryption key. Any missing or misjudging in retransmission sequence would prevent the adversary from
achieving the keys. In addition with this we introduce a new protocol, Integrated Authentication and Confidentiality (IAC), to
provide efficient secure AMI communications in smart grid. With the help of IAC, an AMI(Advanced Metering Infrastructure)
system can provide trust services, data privacy, and integrity by mutual authentications whenever a new smart meter initiates
and joins the smart grid AMI network.
