Efficient Identity-based Sanitizable Signature Scheme in Standard Model
Rui Li · 2013
Sanitizable signature scheme allows stanitizer to modify the specific part of the original message without interacting with the signer to generate a valid signature to modify the message.This paper came up with an identity-based sanitizable signature scheme design based on Waters technology and Li technology under the standard model with the application of bilinear pairings.The safty analysis shows that the proposed scheme is able to satisfy the characteristics of unforgeability,indistinguishability and immutability.Compared with the the existing safty scheme under the standard model,this design has higher computational efficiency and smaller communication cost.
