摘　　要：针对安全领域中海量数据密码服务请求造成的高并发、加解密运算随机交叉现象,提出并实现一种关联业务数据迁移的流数据并行处理系统。通过构造特定的通信作业包,利用进程号、业务号、算法标识等属性信息区分来自不同链接数据流的不同业务请求,在算法核前端增设关联内容可寻址存储器(CAM),实现关联作业包的并行查找,快速定位;算法核后端增设关联FIFO,降低业务数据交叉情况下关联作业包管理需要的存储容量,增加关联存储空间利用率。在多种不同应用同时请求密码运算服务的场景下,该系统可以实现对交叉业务数据的正确处理,避免输入数据流阻塞现象的发生,实现业务数据的不间断高速处理。Aiming at the high concurrcncy and decryption random crossover caused by massivc data password scrvice requests in the security field,a flow data parallel processing system with associated business data migration was proposed and implemented.By constructing spccific communication job packets,different business requests from different linked data streams were distinguished using process number,business number,algorithm identification and other attribute information.Association comentaddressable memories(CAMs)were added in the front end of the algorithm core to realize the parallel search and fast location of the associated job packet,and association FIFOs were added at the back end of the algorithm core to reduce the storage capacity needed for the management of the associated job packet under the condition of business data crossing,and the utilization rate of associated storage space was increased.When various different applications simultaneously request the cryptographic operation service,the system can realize the correct processing of cross-business data,avoid the occurrence of input data flow blocking phenomenon,and realize the continuous and high-speed processing of business data.
