为使群签名同时具有匿名性与可追踪性(发生争议时可打开)，群签名的执行效率往往比较低下。

For providing anonymity and traceability (which means signatures can be opened in dispute cases) at the same time, the efficiencies of group signature schemes are usually lower.

为使群签名同时具有匿名性与可追踪性（发生争议时可打开），群签名的执行效率往往比较低下。

Though providing both anonymity and traceability(which means signatures can be opened in dispute cases), most group signature schemes achieve these features at the cost of performing efficiency.
