Webb14 mars 2014 · A proxy blind signature refers to a digital signature mechanism that fulfills the security properties of proxy as well as blind signatures. In such a scheme, the original signer assigns his signing right to the proxy signer due to special reasons. This means that the proxy signer produces a blind signature on behalf of the actual signer.
