摘　　要：传统通信加解密设备在测试阶段受限于加解密设备数量的不足,无法模拟真实场景下大数量级加解密设备对加解密系统的稳定性测试,基于此问题,提出一种加解密模拟终端设备设计方法,利用线程池技术降低设备开辟线程带来的系统资源损耗问题,同时提高设备的并发性;通过建立任务完成时间预测模型,利用最小二乘支持向量回归算法动态预测各线程处理时间并依此确定线程优先级进行调度,保证模拟设备的时延与响应能力,使其能够支持对加解密设备的性能测试。Traditional communication encryption and decryption devices are limited by insufficient quantities during testing stages,preventing the simulation of large-scale deployment scenarios to test the stability of encryption and decryption systems.Based on this issue,a design method for a simulated encry-ption and decryption terminal device is proposed.The method utilizes thread pool technology to reduce the system resource drain associated with initiating threads,while also increasing the device's concurrency.By establishing a task completion time prediction model and applying the LS-SVR to dynamically predict the processing time of each thread,thread priorities can be determined for scheduling to ensure the simulated device's latency and response capabilities,enabling it to support performance testing for encryption and decryption devices effectively.
