Sanitizable signatures introduced by Ateniese et al. is a powerful and fairly practical tool that enables an authorised party called the censor to modify designated parts of a signed message in an arbitrary way without interacting with the signer. In our paper we present several extensions of this paradigm that make sanitizable signatures even more useful. First of all we show how to limit the censor's abilities to modify mutable parts of a signed message to a predetermined set of strings. In our next proposal we show how to construct a scheme wherein the censor can insert an arbitrary string into a document, but this must be the same string in all designated places. We also present a construction based on a sanitizable signature that allows the censor to present only a constant number of versions of the sanitized message. Another extension provides so-called strong transparency. In this case the verifier does not know which parts of the message could have been modified. Finally, we point out new applications of sanitizable signatures based on combining them with time released cryptography techniques.
