IPV6 is the next generation networking protocol. It can provide more address space than IPV4 and more secure service. This paper studies the technical features of the IPv6 protocol, discusses IPv6 network security mechanisms.
With widely applications of Multi-Agent System (MAS) on internet and intranet, how to ensure security regarding multi-agent communication is a big issue. Traditional cryptographic technologies support a coarse granularity security. This paper adopts XML security technology to provide a security mechanism for MAS communication. With the combination of XML security specifications and MAS, the paper presents a fine-grained security model for MAS communication. The model proposed can satisfy the security requirements of MAS communication based on XML data format.
First, as the 4G network, the introduction of IPv6 network layer security mechanism, security is enhanced at the same time, IPv6 security mechanism applied to the 4G network system security as well as new demands and challenges, followed by the core network based on IPv6 network security to face the next 4G threats and security problems, concludes with IPv6 technical analysis and 4G network defense and countermeasures.
