中文摘要：

该文给出了一个基于身份的具有消息恢复功能的签名方案，该签名方案可以看作是Abe—Okamoto签名方案的基于身份的版本．在随机预言模式下，证明了该方案对自适应选择消息和身份攻击是存在性不可伪造的．该签名方案通过消息恢复功能缩短了消息及其签名的总长度，因此它非常适应于传输带宽受限的环境，例如移动Ad Hoc网络．

英文摘要：

In this paper, the authors present a new identity-based signature scheme with message recovery. This scheme can be regarded as the identity-based version of Abe-Okamoto＇s scheme and is proved secure against existential forgery under adaptive chosen message and ID attack in the random oracle model. This new scheme shortens the total length of the original message and the appended signature.
