A Cautionary Note on Automatic Proxy Configuration
- …Web proxies can be used for a variety of services. Web browsers typically offer the option not only to statically configure a web proxy, but also to download proxy settings dynamically from the Internet. Unfortunately, the supporting infrastructure does not enable the browsers to properly authentica…

Using GSM/UMTS for Single Sign-On
- …At present, network users have to remember a username and a corresponding password for every service with which they are registered. Single Sign-On (SSO) has been proposed as a solution to the usability, security and management implications of this situation. Under SSO, users authenticate themselves…

Linking anonymous transactions: The consistent view attack
- …Abstract. In this paper we study a particular attack that may be launched by cooperating organisations in order to link the transactions and the pseudonyms of the users of an anonymous credential system. The results of our analysis are both positive and negative. The good (resp. bad) news, from a pr…

Impostor: A Single Sign-On System for Use from Untrusted Devices
- …At present, network users have to manage a set of authentication credentials (usually a username/password pair) for every service with which they are registered. Single Sign-On (SSO) has been proposed as a solution to the usability, security and management implications of this situation. Under SSO, …

Attacking Unlinkability: The Importance of Context
- …Abstract. A system that protects the unlinkability of certain data items (e. g. identifiers of communication partners, messages, pseudonyms, transactions, votes) does not leak information that would enable an adversary to link these items. The adversary could, however, take advantage of hints from t…

Limits to Anonymity when Using Credentials
- …This paper identifies certain privacy threats that apply to anonymous credential systems. The focus is on timing attacks that apply even if the system is cryptographically secure. The paper provides some simple heuristics that aim to mitigate the exposure to the threats and identifies directions…

A Security Model for Anonymous Credential Systems
- …This paper proposes a formal model of the Bellare-Rogaway type [Bellare and Rogaway, 1994] that enables one to prove the security of an anonymous credential system in a complexity theoretic framework. The model abstracts away from how a specific instance of anonymous credential system achieves its g…
