Abstract
Non-transferability of digital signatures is an important security concern, traditionally achieved via interactive verification protocols. Such protocols, however, are vulnerable to "online transfer attacks" - i.e., attacks mounted during the protocols' executions. In this paper, we show how to guarantee online untransferability of signatures, via a reasonable public-key infrastructure and general assumptions, without random oracles. Our untransferable signatures are as efficient as prior ones that provably provide weaker types of untransferability. © 2008 Springer-Verlag Berlin Heidelberg.
