摘　　要：波形文件加载是软件定义无线电技术(SDR)的重要环节。随着SDR的广泛应用和安全形势的不断恶化,波形文件加载过程中的安全和可靠性问题显得越来越重要。针对波形文件加载的安全和可靠性问题,以vxworks操作系统为基础软件环境,以GPP目标文件、DSP目标文件和FPGA目标文件为波形文件组成部分,提出了包括访问控制技术、特征值签名技术、认证-应答机制和成套性鉴别在内的安全策略。通过实施该策略,可以显著提升波形文件加载的安全性和可靠性。Waveform file loading is very important to SDR(Software Defined Radio)technology.With the extensive application of SDR and continuous deterioration of security situation,security and reliability problems of waveform file loading become more and more important.Aiming at these problems,the security strategy involving access control,finger printing,sign-answer and information checking is proposed,based on vxworks operation system and with GPP,DSP and FPGA target files as the components of waveform files.The implementation of this strategy indicates that the security and reliability of waveform file loading could be significantly improved.
