Abstract interdomain security assertions: A basis for extra-grid virtual organizations

Philippe Janson

One significant challenge in building grids between organizations with heterogeneous security systems is the need to express and enforce security policies that specify the users in one organization (the source domain) who are allowed to access the resource ...

State of the art in electronic payment systems

Philippe Janson

The exchange of goods conducted face-to-face between two parties dates back to before the beginning of recorded history. Traditional means of payment have always had security problems, but now electronic payments retain the same drawbacks and add some risk ...

Scalability and flexibility in authentication services: The KryptoKnight approach

Philippe Janson

This paper studies the issues of flexibility and scalability in the context of network security. In particular, it concentrates on authentication and key distribution services suited for a variety of communication paradigms, network environments, and end-d ...

1997

Robust and secure password and key change method

Philippe Janson

This paper discusses issues and idiosyncrasies associated with changing passwords and keys in distributed computer systems. Current approaches are often complicated and fail to provide the desired level of security and fault tolerance. A novel and very sim ...

KryptoKnight family of light-weight protocols for authentication and key distribution

Philippe Janson

An essential function for achieving security in computer networks is reliable authentication of communicating parties and network components. Such authentication typically relies on exchanges of cryptographic messages between the involved parties, which in ...

Secure and minimal protocols for authenticated key distribution

Philippe Janson

The problem of secure key distribution has been the subject of much attention in recent years. This paper describes a novel method for authenticated key distribution in the distributed systems environment. In particular, a braiding technique for key distri ...

1995

Systematic design of a family of attack-resistant authentication protocols

Philippe Janson

The extensive use of open networks and distributed system poses serious threats to the security of end-to-end communications and network components themselves. A necessary foundation for securing a network is the ability to reliably authenticate communicat ...

Architectural directions for opening IBM networks: The case of OSI

Philippe Janson

The authors discuss the results of a research project that developed an architectural framework for integrating non-IBM network architectures with the reference model and node structures of IBM's System Network Architecture (SNA). The unique features of th ...

1991

Heterogeneity and OSI

Philippe Janson

A review is presented of the different aspects of heterogeneity that need to be resolved to achieve global interoperability, and specifically, to provide global transport service. It concentrates on the problems of interconnecting computer networks and sys ...

1990

Interconnecting heterogeneous networks to osi with a global name scheme and gateway address mapping.

Philippe Janson

The ongoing development of the OSI standards for computer communication prompts existing networks to provide OSI inteconnectivity. Achieving this requires two mechanisms: a global scheme to name applications, and specific solutions to provide internetwork ...
