Addressing and privacy support for 6LoWPAN
In most of the current IPv6 addressing protocols, a node's IP address remains unchanged during its lifetime. Since addresses are a fundamental requirement of communications and cannot easily be hidden from eavesdroppers, eavesdroppers may track a node's activities via checking its IPv6 address. Consequently, the use of a constant address is of special concern, and changing an address regularly is desirable to lessen privacy concerns. This paper proposes an IPv6 over low-power wireless personal area network addressing scheme with privacy support. In this scheme, a node regularly changes its address without extra overheads and the size of an address set is randomly generated, the address privacy is achieved. This scheme is analyzed and evaluated, and the data show that this scheme achieves the address privacy and improves the addressing performance.
