Efficient Invisible and Unlinkable Sanitizable Signatures
public-key cryptography Unlinkable Sanitizable Signatures
2019/6/5
Sanitizable signatures allow designated parties (the sanitizers) to apply arbitrary modifications to some restricted parts of signed messages. A secure scheme should not only be unforgeable, but also ...

Sanitizable Signatures Chameleon-Hashes Digital Signatures
2019/4/23
Sanitizable signatures allow a single, and signer-defined, sanitizer to modify signed messages in a controlled way without invalidating the respective signature. They turned out to be a fascinating pr...

2018/11/14
Sanitizable signature schemes (SSS) enable a designated party (called the sanitizer ) to alter admissible blocks of a signed message. This primitive can be used to remove or alter sensitive data from ...

2018/4/12
Sanitizable signature schemes are signature schemes which support the delegation of modification rights. The signer can allow a sanitizer to perform a set of admissible operations on the original mess...
Unlinkable and Strongly Accountable Sanitizable Signatures from Verifiable Ring Signatures
Sanitizable signature Ring signature Unlinkability
2017/6/27
A Unlinkable Sanitizable Signature scheme (USS) allows a sanitizer to modify some parts of a signed message such that nobody can link the modified signature to the original one. A Verifiable Ring Sign...

2017/5/25
Sanitizable signatures are a variant of digital signatures where a designated party (the sanitizer) can update admissible parts of a signed message. At PKC’17, Camenisch et al. introduced the notion o...

2017/3/27
Sanitizable signatures, introduced by Ateniese et al. (ESORICS '05), allow the signer to delegate the sanitization right of signed messages. The sanitizer can modify the message and update the signatu...
Chameleon-Hashes with Ephemeral Trapdoors And Applications to Invisible Sanitizable Signatures
chameleon-hash functions chameleon-hash functions with ephemeral trapdoors trapdoor commitments
2017/2/20
A chameleon-hash function is a hash function that involves a trapdoor the knowledge of which allows one to find arbitrary collisions in the domain of the function. In this paper, we introduce the noti...
Efficient Unlinkable Sanitizable Signatures from Signatures with Rerandomizable Keys

2015/12/31
Sanitizable signature schemes are a type of malleable signatures where the signer grants a designated
third party, called the sanitizer, signing rights in the sense that the sanitizer can modify desi...

2015/12/23
Sanitizable signatures, introduced by Ateniese et al. at ESORICS’05,
allow to issue a signature on a message where certain predefined
message blocks may later be changed (sanitized) by some dedicate...
