1-out-of-n Signatures from a Variety of Keys
[chapter]
2002
Lecture Notes in Computer Science
Preserved Fulltext
We present a widely applicable method to construct a 1-out-of-n signature scheme that allows mixture use of different flavors of keys at the same time. ...
This paper addresses how to use public-keys of several different signature schemes to generate 1-out-of-n signatures. Previously known constructions are for either RSA-keys only or DL-type keys only. ...

Concurrent signatures allow two entities to produce two ambiguous signatures that become binding once an extra piece of information (called the keystone) is released. ...
Such a signature is developed by Chen et al., but it restricts signers to using the same public parameters. ...
Using a variation of Abe et al.'s 1-out-of-n signature with key separation, we introduce a concurrent signature in the separable model. ...

The first one assumes that the signer hides his identity in n independently generated public keys, while the second one assumes that all n public keys share the same public parameters. ...
In this work, we formalize this type of signature, introduce the corresponding security requirements and describe two instantions. ...
In this case, we can see that a mixture of an 1-out-of-n 1 signature and an n 2 message oblivious signature can offer a possible solution. ...

Our signature scheme has a multiple ring structure, each ring of which is based on 1-out-of-n ring signature. ...
Our signature has a remarkable property: When the signature is updated from k-out-of-n to (k + α)-out-of-n, the previous signers do not need to sign a message again. ...
This time they want to update the signature from k-out-of-n to (k+α)-out-of-n ring signatures. ...
