摘　　要：针对CPU上计算机指令的执行消耗大量的资源,以及FPGA的通用,提出专用领域可重构算粒集的概念。算粒集的执行并非按指令执行,以硬件可重构方式完成不同粒度的功能单元实现,减少大量资源的消耗,同时专用于密码领域。以密码领域WinZip口令恢复的算粒集的提取验证为例,在不同平台上使用与未使用可重构算粒集实现WinZip口令验证,充分说明了在密码领域使用可重构算粒集的优越性。In light of the issue that executing computer instructions on CPU costs a great deal of resources,and of the universality of FPGA,we present the concept of reconfigurable algorithm set for special field.The execution of the algorithm set does not execute according to the instructions,but is implemented by completing the functional units with different granularities in the way of hardware reconfiguration,which reduces an amount of resource consumption,and is dedicated to the password field.Taking extracting and authenticating the algorithm set of Win Zip password recovery in password field as an example,the use of or not use of the reconfigurable algorithm set on different platforms for achieving Win Zip password authentication fully demonstrates the superiority of the use of the reconfigurable algorithm set in password field.
