!!! Overview
[{$pagename}] ([CL Signature] Camenisch-Lysyanskaya) are a form of [Digital Signature] invented by Jan Camenisch and Anna Lysyanskaya in [2001|Year 2001].
In addition to being secure [Digital Signatures], they need to allow for the efficient implementation of two [protocols]:
* A protocol for computing a [Digital Signature] in a secure two-party computation protocol.
* A protocol for proving knowledge of a [Digital Signature] in a [Zero-knowledge proof] protocol.
In applications the first [protocol] allows a signer in possession of the signing [key], to issue a [Digital Signature] to a user (the signature owner) without learning all the [messages] being signed or the complete signature.
The second [protocol] allows the signature owner to prove that he has a signature on a number of [messages], without revealing the [Digital Signature] and only a (possibly) empty subset of the [messages].
The combination of these two [protocols] allows for the implementation of digital credential and [ecash] [protocols].
[{$pagename}] may have [United States] and other country [Patents] [{$pagename}] is a form of a [Group Signatures]
[{$pagename}]s have been enhanced since the original.
