摘　　要：针对现有单属性机构属性签名方案存在安全性和效率不能满足实际应用需求问题,提出一种支持多属性机构属性签名方案。将单属性机构扩展为多属性机构,每个属性机构管理不同的属性集合,减少单属性机构所需存储和计算开销,降低系统崩溃的风险;签名时采用拒绝抽样技术,使得该构造在公钥、私钥和签名上具有更高空间利用率;利用格上小整数解问题来构造属性签名,确保效率和安全性;最后证明该方案在随机预言模型下是存在不可伪造的。该方案相较于其他方案性能是高效且实用。Aiming at the problem that the security and efficiency of the existing single-attribute agency attribute signature schemes that cannot meet the practical application requirements,an attribute signature scheme supporting multi-attribute organizations is proposed.The single-attribute mechanism is extended to a multiattribute mechanism,and each attribute mechanism manages a different set of attributes,which reduces the storage and computation overhead required by the single-attribute mechanism,and reduces the risk of system crash;The signature adopts the rejection sampling technique,and the construction has a higher space utilization rate on the public key,the private key,and the signature;The attribute signature is constructed by using the problem of the small-integer solution on the lattice,which ensures the efficiency and security.Finally,it is proved that the scheme is existentially unforgeable under the stochastic prediction model,and the performance of the scheme is efficient and practical compared with other schemes.
