A Security Information Transmission Scheme for Internet of Things

IoT (Internet of Thing), which is based on the EPCglobal architecture, has information transmission security risks in tag reading and ONS query process. It needs appropriate security scheme to achieve data confidentiality, access control, client privacy protection and other features in order to resist sophisticated attacks. In this paper, a secure transmission scheme without trusted center is discussed and an extension DNS protocol is proposed to enhance the security of ONS query process. In this protocol, designing of multi-KGC center and the application of CL-PKC (certificate less public key cryptography) can not only improve system fault tolerance ability, but also avoids the traditional complicated management of certificates. This paper also studies the implement of our scheme, including query protocols, virtual reader and middleware system.
