Context: The majority of efforts devoted to improve security enforcement architectures have been characterized by sacrificing system resources. However, such approach is no longer appropriate for information systems dedicated to mobile devices (e.g., mobile phones and smartphones), which are characterized by strict memory and power limitations. Objectives: The long-term objective is the exploration of new approaches to allow efficient enforcement of security policies on resource constrained systems. The short-term objectives are (1) analyzing the security of mobile systems to evaluate the vulnerabilities and assess the underlying risks, understand security policies that should be enforced, and identify opportunities for efficient enforcement, (2) formally characterizing security enforcement to investigate enforceable security policies and constrained security enforcement, and (3) defining domain-specific languages for specifying security policies and providing the appropriate mechanisms required for enforcing them efficiently. Scientific Approach: This research program targets the investigation of important issues related to the security of resource-constrained systems. One important issue targeted by the research is analyzing the security of these systems. The objective is to reach the most complete vision of (1) the security attacks threatening mobile systems, (2) the vulnerabilities facilitating their achievement, and (3) the underlying risks. The results of such analysis will be leveraged to generate a classification of security policies to be enforced. The target enforcement mechanisms will be built on top of formal foundations allowing the evaluation of required resources as well as identification of optimization opportunities. In addition, a bridge will be built between the proposed formal models and high-level security policies specification languages. Appropriate languages will be defined to allow specifying security policies and their efficient enforcement on mobile systems. Generic enforcement mechanisms will be generated and optimized when embedded inside mobile applications.

背景：致力于改善安全执法架构的大多数努力是通过牺牲系统资源来表征的。但是，这种方法不再适用于专用于移动设备（例如手机和智能手机）的信息系统，这些信息以严格的内存和电源限制为特征。 目标：长期目标是探索新方法，以便在资源约束系统上有效执行安全策略。短期目标是（1）分析移动系统的安全性，以评估脆弱性并评估潜在的风险，了解应执行的安全政策，并确定有效执行的有效执行的机会，（2）正式表征安全执行，以调查可执行的安全策略，并为特定的安全性提供规定的安全性，并（3）特定的安全性，（3）（3）（3）（3）（3）（3）（3）（3）（3）（3）（3）有效地执行它们。 科学方法：该研究计划针对与资源受限系统安全性有关的重要问题的调查。研究针对的一个重要问题是分析这些系统的安全性。目的是达到（1）威胁移动系统的安全攻击，（2）促进其成就的脆弱性，以及（3）基本风险。这种分析的结果将被利用，以生成要执行的安全策略的分类。目标执法机制将建立在正式基础之上，以评估所需的资源以及确定优化机会。此外，将在拟议的正式模型和高级安全策略规范语言之间建造桥梁。 将定义适当的语言，以允许在移动系统上指定安全策略及其有效执行。嵌入移动应用程序中时，将生成和优化通用的执行机制。
