- Designing the Mobile IPv6 Security Protocol
- Mobile IPv6 is a network-layer mobility protocol for the IPv6 Internet. The protocol includes several security mechanisms, such as the return-routability tests for the care-of addresses. This paper explains the threat model and design principles that motivated the Mobile IPv6 security features. While many of the ideas have become parts...

- A Look Back at "Security Problems in the TCP/IP Protocol Suite"
- Earlier, the author wrote a paper on security problems in the TCP/IP protocol suite. In particular, he focused on protocol-level issues, rather than implementation flaws. It is instructive to look back at that paper, to see where his focus and predictions were accurate, where he was wrong, and where dangers...

- Analysis of the HIP Base Exchange Protocol
- The Host Identity Protocol HIP is an Internet security and multi-addressing mechanism specified by the IETF. HIP introduces a new layer between the transport and network layers of the TCP/IP stack that maps host identifiers to network locations, thus separating the two conflicting roles that IP addresses have in the...

- Discoverer: Automatic Protocol Reverse Engineering From Network Traces
- Application-level protocol specifications are useful for many security applications, including intrusion prevention and detection that performs deep packet inspection and traffic normalization, and penetration testing that generates network inputs to an application to uncover potential vulnerabilities. However, current practice in deriving protocol specifications is mostly manual. This paper presents Discoverer,...

- Dynamic Model Checking of C Cryptographic Protocol Implementations
- This paper describes the Dolev-Yao C DYC cryptographic protocol message API. In addition to generating executable protocol implementations, DYC can be used to generate constraints on an attacker against the protocol. The resulting constraints can be handed to a constraint solver, which if successful will find an executable attack against...

- On Security in TCP/IP Over Wireless Network
- The Transmission Control Protocol/Internet Protocol (TCP/IP) is combination of different protocols at various layers. TCP/IP is the basic communication language or protocol of the Internet and private networks either an intranet or an extranet. TCP interfaces between the application layer and the network layer. It is a connection oriented, reliable...

- The Teredo Protocol: Tunneling Past Network Security and Other Security Implications
- Teredo is a platform-independent protocol developed by Microsoft, which is enabled by default in Windows Vista. Teredo provides a way for nodes located behind an IPv4 NAT to connect to IPv6 nodes on the Internet. However, by tunneling IPv6 traffic over IPv4 UDP through the NAT and directly to the...

- Model Checking Large Network Protocol Implementations
- Network protocols must work. The effects of protocol specification or implementation errors range from reduced performance, to security breaches, to bringing down entire networks. However, network protocols are difficult to test due to the exponential size of the state space they define. Ideally, a protocol implementation must be validated against...

- Generic Application-Level Protocol Analyzer and Its Language
- Application-level protocol analyzers are important components in tools such as intrusion detection systems, firewalls, and network monitors. Currently, protocol analyzers are written in an ad-hoc fashion using low-level languages such as C, incurring a high development cost and security risks inherent in low-level language programming. Motivated by the large number...

- Specification-Based Intrusion Detection System for Carrier Ethernet
- Layered network architectures (OSI, TCP/IP) separate functionality in layers, allowing them to be designed and implemented independently. However, from the security point of view, once a lower layer is compromised, the reliability of the higher layers can be impaired. This paper is about the security of the Data Link Layer,...
