摘　　要：针对简单加密算术库(simple encrypted arithmetic library, SEAL)应用编程接口(application programming interface, API)类较多、不利于其与应用之间松耦合的问题,以BFV方案为例,提出一种基于门面设计模式的SEAL库API类优化设计方法。通过增加门面类,将多个API类封装在门面类内部,应用通过门面对象访问SEAL库,交互的API类从12个减少为3个。使用优化前后的API类设计测试程序,对功能和性能进行测试验证。测试结果表明,优化设计具备可行性,对性能的影响较小。The homomorphic encryption library SEAL provides a little more API classes,which is not conducive to the loose coupling between itself and the applications,taking the BFV scheme as an example,a design method for the SEAL’s API classes optimization based on the facade design pattern was proposed.By adding a facade class,several API classes were encapsulated inside the facade class.As a result,the applications can access the SEAL library through the facade object,and the number of the interactive API classes was reduced from 12 to 3.A test program that used the API classes before and after optimization was designed to test and verify the functionality and performance.The test results show that the optimized design is feasible,and has little impact on performance.
