%X The existing chameleon hash-based constructions do not achieve full privacy, while the group signature-based construction that achieves full privacy was not efficient enough and thus not practical. In order to solve this problem, this paper proposed a new sanitizable signature scheme. The construction was based on conventional digital signature scheme, the BLS signature scheme and public key encryption scheme, and meet all the fundamental security requirements of sanitizable signatures, i.e., unforgeability, immutability, transparency, full privacy and accountability, and reached higher computational efficiency than group signature-based construction and thus higher practicality.
