Abstract

Given the high cost of producing software, development of technology for prevention of software piracy is important for the software industry. In this paper we present a novel approach for preventing the creation of unauthorized copies of software. Our approach splits software modules into open and hidden components. The open components are installed (executed) on an insecure machine while the hidden components are installed (executed) on a secure machine. We assume that while open components can be stolen, to obtain a fully functioning copy of the software, the hidden components must be recovered. We describe an algorithm that constructs hidden components by slicing the original software components. We argue that recovery of hidden components constructed through slicing, in order to obtain a fully functioning copy of the software, is a complex task. We further develop security analysis to capture the complexity of recovering hidden components. Finally we apply our technique to several large Java programs to study the complexity of recovering constructed hidden components and to measure the runtime overhead introduced by splitting of software into open and hidden components.

隐藏程序片段以保证软件安全

鉴于生产软件的高成本，开发防止软件盗版的技术对软件行业来说非常重要。在本文中，我们提出了一种防止创建未经授权的软件副本的新方法。我们的方法将软件模块分为开放组件和隐藏组件。开放组件在不安全的机器上安装(执行)，而隐藏组件在安全的机器上安装(执行)。我们假设，虽然开放的组件可以被盗，但要获得软件的完整功能副本，必须恢复隐藏的组件。我们描述了一种通过对原始软件组件进行切片来构造隐藏组件的算法。我们认为，恢复通过切片构造的隐藏组件，以获得软件的完整功能副本，是一项复杂的任务。我们进一步开发安全分析，以捕获恢复隐藏组件的复杂性。最后，我们将该技术应用于几个大型Java程序，以研究恢复构造的隐藏组件的复杂性，并测量将软件分为开放组件和隐藏组件所带来的运行时开销。
