摘要：M2M (Machine-to-Machine Communication) refers to technologies that allow wired and wireless systems to communicate with other devices with similar capabilities. M2M has special features which consist of low electricity consumption, cheap expenses, WAN, WLAN and others. Therefore, it can communicate via a network. Also, it can handle itself without a person's management. However, it is difficult to manage and control each equipment because of the characteristics of M2M, and it succeeds the weaknesses and security threats of existing wired and wireless networks as it is still used. So In this Paper, It suggests the privacy protection technique planning among Device, Gateway and Network Domain in the M2M environment. The proposal protocol protects a privacy and it also assures a confidentiality and an integrity of the messages when it communicates through Device Domain and Network Domain by using the attribute based cryptography.
