Provably Secure Partially Blind Signatures
[chapter]
2000
Lecture Notes in Computer Science
Preserved Fulltext
Partially blind signature schemes are an extension of blind signature schemes that allow a signer to explicitly include necessary information (expiration date, collateral conditions, or whatever) in the ...
We then give a formal proof of security in the random oracle model. Our approach also allows one to construct secure fully blind signature schemes based on a variety of signature schemes. ...
All in all, no provably secure and practical partially blind signature scheme has been publicly released. ...
