Evaluation of security regarding Z-Wave wireless protocol

In the early adoptions of Z-Wave protocol for smart home automation, security issues were not taken into consideration. As this protocols got higher adoption rates, more security studies were performed to increase the security level of this protocol and solve many of the security bugs founds. The first issue, the protocols has no encryption and weak security procedures adopted to protect the commands during transmissions. There were significant improvements in order to make this protocol security levels reach AES 128-bit encryption, which is the same level of protection major banks use. In this paper, our researcher is focused on vulnerabilities, weakness and how the administrators can protect their home area networks (HANs) that uses Z-wave protocol with an additional security.
