中文摘要：

该文针对现有的无证书环签名大多都使用昂贵的双线性对的问题,利用前向环序列提出一个无双线性对的无证书环签名方案,并对该方案的性能进行了详细的分析。与已有的无证书环签名相比,它完全避免了双线性对运算,计算成本降低,实用性更强。

英文摘要：

Since the existing certificateless ring signatures uses expensive pairings,a new certificateless ring signature scheme without pairings is proposed.It is based on forward loop sequence and its performance is analyzed in detail.Compared with other certificateless ring signature schemes,this scheme is more practical because it has completely avoided pairing and reduced the computational cost.
