    • Procedures are described for enhancing target system execution integrity determined by power fingerprinting (PFP): by integrating PFP into the detection phase of comprehensive defense-in-depth security; by deploying a network of PFP enabled nodes executing untrusted devices with predefined inputs forcing a specific state sequence and specific software execution; by embedding module identification information into synchronization signaling; by combining signals from different board elements; by using malware signatures to enhance PFP performance; by automatic characterization and signature extraction; by providing secure signature updates; by protecting against side- channel attacks; performing real-time integrity assessment in embedded platform by monitoring their dynamic power consumption and comparing it against signatures from trusted code, including pre-characterizing power consumption of the platform by concentrating on trace sections carrying the most information about the internal execution status; by using PFP from sequence of bit transitions to detect deviations from authorized execution of software in a digital processor.
    • 描述了用于增强由功率指纹识别(PFP)确定的目标系统执行完整性的程序:通过将PFP整合到综合纵深防御安全的检测阶段中; 通过部署启用PFP的节点的网络来执行具有预定义输入的不可信设备,强制执行特定的状态序列和特定的软件执行; 通过将模块标识信息嵌入到同步信令中; 通过组合来自不同板单元的信号; 通过使用恶意软件签名来增强PFP性能; 通过自动表征和签名提取; 通过提供安全签名更新; 通过保护免受旁道攻击; 通过监测其动态功耗并与来自可信代码的签名进行比较,在嵌入式平台上执行实时完整性评估,包括通过集中于运行关于内部执行状态的大多数信息的跟踪部分来预先表征平台的功耗; 通过在比特转换序列中使用PFP来检测数字处理器中软件授权执行的偏差。
