Secure CoAP-based Group Mobility Management in the Internet of Things.

Abstract

In the current age as many types of embedded devices or sensor have been introduced to Internet of Things (IoTs) so, the Protocol named CoAP has been widely used. The critical issue based on web in IoTs environment was mobility management. To reduce this limitation the proposed solution was a protocol named (CoMP). To manage the location changes CoMP exchanges Binding Update (BU) messages but these messages have many security vulnerabilities like false BU, man in the middle attack (MITM), session hijacking, denial of service (DoS), false BU, session hijacking. To secure these BU messages the proposed scheme was PKBU-CoMP which protects the BU messages between mobile nodes and clients, but this scheme was developed considering single mobile sensor node so, it doesn’t perform group-based mobility. To tackle this problem, we proposed a CoMP-base secure scheme for group of sensors named (PKBU-CoMP-SG). By applying this scheme we will first improve the PKBU-CoMP technique to make it for group of mobile sensor nodes by applying CoAP-base CoMP for group scheme and in this scheme one of body sensors acts as an administrator and it is responsible for the controlling of all kinds of messages with information mobility management server (IMMS) on the favor of other sensor nodes and every IMMS will maintain the information of its group of sensor nodes and then we will apply single node mobility security to group of nodes mobility by applying private key to protect BU CoMP messages
