An Inconvenient Truth About Tunneled Authentications

October 10, 2010

Author(s)

Katrin Hoeper, Lidong Chen

In recent years, it has been a common practice to execute client authentications for network access inside a protective tunnel. Man-in-the-middle (MitM) attacks on such tunneled authentications have been discovered early on and cryptographic bindings are

Recommendation for EAP Methods Used in Wireless Network Access Authentication

September 17, 2009

Author(s)

Lidong Chen, Katrin Hoeper

This Recommendation specifies security requirements for authentication methods with key establishment supported by the Extensible Authentication Protocol (EAP) defined in IETF RFC 3748 for wireless access authentications to federal networks.

Recommendation for Pair-Wise Key Establishment Schemes Using Integer Factorization Cryptography

August 28, 2009

Author(s)

Elaine B. Barker, Lidong Chen, Andrew R. Regenscheid, Miles E. Smid

[Superseded by SP 800-56B Rev. 1 (September 2014): http://www.nist.gov/manuscript-publication-search.cfm?pub_id=916341] This recommendation specifies key establishment schemes using integer factorization cryptography, based on ANS X9 44, Key Establishment

Security Challenges in Seamless Mobility - How to ``Handover'' the Keys?

November 30, 2008

Author(s)

Katrin Hoeper, Lidong Chen, Antonio Izquierdo Manzanares, Nada T. Golmie

In this paper, we discuss key management challenges for seamless handovers across heterogeneous wireless networks. We focus on fast access authentication protocols that allow expedited network entry by utilizing existing keying material from previous

Using the EAP Framework for Fast Media Independent Handover Authentication

November 17, 2008

Author(s)

Antonio Izquierdo Manzanares, Nada T. Golmie, Katrin Hoeper, Lidong Chen

In this paper we compare different authentication techniques that may be used in order to reduce the time and resources required to perform a handover, namely, re-authentication and pre-authentication. We provide a detailed analysis of each mechanism, and

Recommendation for Key Derivation Using Pseudorandom Functions

November 12, 2008

Author(s)

Lidong Chen

This Recommendation specifies techniques for the derivation of additional keying material from a secret key, either established through a key establishment scheme or shared through some other manner, using pseudorandom functions.
