We introduce the notion of sanitizable signatures that offer many attractive security features for certain current and emerging applications. A sanitizable signature allows authorized semi-trusted censors to modify -in a limited and controlled fashion -parts of a signed message without interacting with the original signer. We present constructions for this new primitive, based on standard signature schemes and secure under common cryptographic assumptions. We also provide experimentaldoi:10.1007/11555827_10 fatcat:sbl7s5zimvcdhkhntipvemv6p4
