| Abstract: | A new sanitizable signature scheme is proposed, in which the security flaw of Miyazaki’s sanitizable signature scheme SUMI-4
is improved. The new scheme overcomes the shortcomings of the original scheme SUMI-4 by using sanitizable authorization certificates.
The new scheme enables the primitive signer to limit the sanitizer’s power and still satisfies the security request of sanitizable
signature.
