A Self-Certified and Sybil-Free Framework for Secure Digital Identity Domain Buildup
2008 (English)Conference paper, (Refereed)
Abstract [en]

An attacker who can control arbitrarily many user identities can break the security properties of most conceivable systems. This is called a Sybil attack. We present a solution to this problem that does

not require online communication with a trusted third party and that in addition preserves the privacy of honest users. Given an initial so-called Sybil-free identity domain, our proposal can be used for deriving Sybil-free unlinkable pseudonyms associated with other identity domains. The pseudonyms are self-certified and computed by the users themselves from their cryptographic long-term identities
