Proxy multi-signature scheme: A new type of proxysignature scheme
Lijang Yi, Guoqiang Bai, Guozhen Xiao · Electronics Letters · 2000
Proxy signature schemes allow a proxy signer to generate a proxy signature on behalf of an original signer. However, since in previous proxy signature schemes a proxy signature is created on behalf of only one original signer, these schemes are referred to as proxy mono-signature schemes. A new type of proxy signature scheme is presented called the proxy multi-signature scheme in which a proxy signer can generate a proxy signature on behalf of two or more original signers.
