摘 要：IPv6 has huge address space,while 128 bit IPv6 address is divided into two parts,namely the address prefix and the interface address.IPv6 provides a wide range of security policies for Internet of Things safety system.The security of the Internet of Things applications interface IPv6 address can be used to identify the node.This paper proposes construction security architecture of the Intemet of Things based on IPv6 technology.In the allocation of the state address safety issues and mobile IPv6 binding buffer security update issues,are able to meet the security needs of the Internet of Things.
