Henry Corrigan-Gibbs: 2014 Security Workshop

"Shorter Ring Signatures and Privacy-Preserving Bitcoin"
2:00pm - 2:30pm

Abstract:

Recent work cleverly applies anonymous signatures to construct a privacy-preserving Bitcoin scheme, in which it is difficult to correlate a single user's Bitcoin transactions over time. The existing techniques are impractical, however, since they increase Bitcoin transaction sizes by roughly 50x. Using new cryptographic tools, we dramatically reduce the size of anonymous Bitcoins and attempt to resolve the tension between privacy and practicality in the Bitcoin system.


Joint work with Joe Zimmerman and Dan Boneh
