摘要
代理聚合签名方案可以将同一原始签名者授权的n个代理签名者对n个不同消息的签名聚合成一个签名.构造了一个新的基于身份的代理聚合签名方案,使之同时具备代理签名和聚合签名的优势,在随机预言机模型下,新方案是可证安全的且效率更高.
A proxy aggregate signature scheme allows n proxy signers to sign n different messages on behalf of a same original signer, and then the n different signatures can be aggregated into a single signature. Construct a new ID-based proxy aggregate signature scheme, which obtains the advantage of proxy signature and aggregate signature meanwhile, and the new scheme is more efficient and is provable security in the random oracle model.
