Abstract: A dual-mode address hopping method is proposed to address security issues faced by the IoT(Internet of Things), such as resource scarcity and low obfuscation of traffic data. Address hopping diversity and unpredictability are enhanced through a dual-mode address selection algorithm, thereby solving the problem of limited address pool resources. Additionally, a dual-virtual address hopping method is introduced to enhance the obfuscation of data packets and reduce the correlation of network data. This method is demonstrated to be effective in reducing network data correlation, conserving IoT resources, increasing network address pool capacity, preventing data theft by attackers, and ensuring IoT security through simulation experiments conducted in an SD-IoT(Software Defined Internet of Things) environment.

Key words: internet of things ( IoT) security, active defense, address hopping, software defined internet of things(SD-IoT)
