Sanitizable signatures with strong transparency in the standard model

Shivank Agrawal, Swarun Kumar, Amjed Shareef and C. Pandu Rangan

Abstract

Sanitizable signatures provide several security features which are useful in many scenarios including military and medical applications. Sanitizable signatures allow a semi-trusted party to update some part of the digitally signed document without interacting with the original signer. Such schemes, where the verifer cannot identify whether the message has been sanitized, are said to possess strong transparency. In this paper, we have described the first efficient and provably secure sanitizable signature scheme having strong transparency under the standard model.
