WebOn Extended Sanitizable Signature Schemes Amandine Jambert Abstract Sanitizable signature schemes allow a semi-trusted entity to modify some specific portions of a signed message while keeping a valid signature of the original off-line signer. Web(tightly) secure signature schemes [11,44,52], but also sanitizable signature schemes [4,15,41] and identity-based encryption schemes [61]. Moreover they are useful in context of trapdoor-commitments, direct anonymous attestation, ... extended framework for chameleon-hashes (without ephemeral trapdoors) first. ...
