A sanitizable signature allows authorized semi-trusted censors to modify - in a limited and controlled fashion - parts of a signed message without interacting ...

Jul 24, 2023 · We propose an accountable policy-based invisible and unlinkable sanitizable signature scheme to solve the above problems. This scheme ...

Jan 18, 2022 · In the ordinary digital signatures, if a signed-message is altered, its signature becomes invalid. In sanitizable.

Here we discuss that a sixth property of sanitizable signature schemes may be desirable: unlinkability. Basically, this property prevents that one can link ...

[21] introduced unlinkability and proposed unlinkable sanitizable signatures based on group signatures. Unlinkability ensures that a sanitized signature ...

Abstract. Sanitizable signatures allow designated parties (the sanitizers) to apply arbitrary modifications to some restricted parts of signed messages.

Jan 20, 2022 · Abstract. Sanitizable signatures (SaS) allow a (single) sanitizer, chosen by the signer, to modify and re-sign a message in a somewhat ...
