Abstract: Online/offline signatures improve online computation through pre-computation. This paper presents message recovery online/offline signature schemes. Because no messages should be transmitted, the scheme can save bandwidth. The new scheme is proven secure under the random oracle model.

Key words: digital signatures, online/offline signatures, message recovery

摘要: 在线/离线签名是利用预处理技巧提高在线签名速度的签名形式。构造了一种可以恢复消息的在线/离线签名方案。因为不需要发送消息,该方案可以大大节约传输带宽。在随机预言模型下,新方案被证明是安全的。
