基于ZigBee的安全消息传输的研究
无线传感器网络具有通信能力有限、电源能量有限、计算速度和存储空间有限、传感器节点配置密集和网络拓扑结构灵活多变等缺陷，不能保证数据信息在传输中机密性，完整性，真实性和时效性。这些缺陷对无线传感器网络的发展极为不利，没有安全可靠的网络传输保证，其在将来的推广中也会大大受阻。这些问题推动了基于ZigBee的安全消息传输的研究。为此，本文从ZigBee网络节点特性和ZigBee通信网的安全机制进行分析和研究，总结出ZigBee消息在应用层的安全传输是问题的关键。因此，提出了一种ZigBee应用层消息安全机制，将无线传感器网络划分为基于簇的分层体系结构，应用了由Diffie-Hellman密钥协商协议扩展的群组密钥协商机制，结合基于CBC模式的DES加密算法，对ZigBee应用层的消息数据进行封装。　　
最后，对本文提出的ZigBee应用层消息安全机制进行实验与分析。本文主要使用CC2530模块组建ZigBee通信网络的硬件平台，并通过接口设备LTC1756和ISO7816的硬件接口驱动程序将SAM卡与CC2530模块进行连接，把本文中提出的ZigBee应用层消息安全机制应用到ZigBee通信网络中，并使用CC2531模块和PacketSniffer（包嗅探器）软件对其应用层消息数据的安全传输进行实验与分析，证明了本文中提出的ZigBee应用层消息安全机制的可行性。再对DES软件、DES硬件、基于CBC模式的DES软件和基于CBC模式的DES硬件等几种加密方式的加密效率进行测试与对比。

CC2531 用于 IEEE 802.15.4 和 ZigBee 应用的片上系统解决方案
The CC2531 is a USB enabled true system-on-chip (SoC) solution for IEEE
802.15.4, ZigBee and RF4CE applications. It enables USB dongles or USB
upgradable network nodes to be built with low total bill-of-material costs. The
CC2531 combines the performance of a leading RF transceiver with an
industry-standard enhanced 8051 MCU, in-system programmable flash memory, 8-KB
RAM, and many other powerful features. The CC2531 has various operating modes,
making it suited for systems where ultralow power consumption is required. Short
transition times between operating modes further ensure low energy consumption.
Source code for USB HID and CDC libraries and examples are downloadable from the
CC2531 product page on www.

Join the Stack Overflow Community
Stack Overflow is a community of 7.0 million programmers, just like you, helping each other.
J it only takes a minute:
I'm trying to understand how to implement a Zigbee module(TI CC2530) into Linux. This module will be connected through SPI to a development card (A80 Pro from Merrii).
At this point, I'm not sure exactly what I have to do. Do I have to write a kernel driver for the CC2530 ? Or just a simple SPI controller driver ?
Also if you have any website that I can look for more informations, it will be great.
You have a number of options here:
The ZigBee Linux HA Gateway reference design (HW/SW):
- Z-STACK-LINUX-GATEWAY
Out of the Box this connects to CC2531 via CDC USB. However by modifying the NPI_Gateway.cfg and the zigbeeHAgw script files you can reconfigure it to use UART or SPI. The CC2530 will need to by preogrammed with the ZNP FW available in
- Z-STACK-HOME SDK under Z-Stack Home 1.2.2.42930\Projects\zstack\ZNP\CC253x, prebuilt binaries are in Z-Stack Home 1.2.2.42930\Projects\zstack\ZAP\ZNP-HexFiles\CC2530.
This option is specifically for Linux, it uses 4 application space servers to manage the Data Plane, Control Plan and Field Upgrade, offering a high level Home Automation API through protobuf over local sockets. It uses the existing CDC, UART or SPI kernel drivers. It would not lend its self to a kernel space driver.
The open source ZNP Host framework reference design. This is cross platform framework and could be ported to a kernel space driver, however it does not support SPI, UART only. The CC2530 FW would be the same as above and does support SPI, so you would need to port the ZNP framework to use SPI.
