Title:
On Transaction Pseudonyms with Implicit Attributes
Authors: Stefan G. Weber
Abstract:Transaction pseudonyms with implicit attributes are a novel approach to multilevel linkable transaction pseudonyms. We extend earlier work of Juels and Pappu on reencryption-based transaction pseudonyms, by developing new mechanisms for controlled pseudonym linkability. This includes mechanisms for cooperative, stepwise re-identication as well as individual authentication of pseudonyms. Our proposal makes use of efficient techniques from the area of secure multiparty computation and cryptographically secure PRNGs.
