Proxy multi-signature and designated-receiver proxy multi-signature schemes
代理多重签名和指定接收人的代理多重签名方案

Proxy multi-signature scheme was first designed on ECDLP. This scheme can not only satisfy all the security requirements, but also avoid wasting time on inversion operations of its signature generation and verification. Then a new designated-receiver proxy signature scheme was proposed, and its security was analyzed.
