Abstract
With the rise and development of new technology of Internet of things, the demand of new intelligent terminal to access the Internet is increasing day by day, and the interconnection of all things is an inevitable trend. The traditional IP protocol in the past can not meet the requirements of "wide access, high-speed interconnection, safe transmission ", but the IPv4（Internet Protocol Version 4） protocol itself has security defects. Traditional Internet is based on IPv4 protocol, the protocol design at the beginning of more consideration of efficiency, security considerations are inadequate, such as IP deception, source routing attacks, network listening and other issues. Therefore IPv6（Internet Protocol Version 6） protocols emerge as the times require, and the application of Internet of things based on IPv6 is becoming more and more common, and then the problems of data transmission security, equipment control security and data exchange security are becoming more and more prominent.Compared with the IPv4, IPv6 did make great progress, mainly in: service quality, security, address capacity and mobility. For the Internet of things technology, IPv6’s progress is of great significance. Based on the data transmission security of IPv6 Internet of things is discussed in this paper, and the countermeasures are put forward to solve the problems of data transmission security of Internet of things .
