Assisted Emulation for Legacy Executables
Emulation is frequently discussed as a failsafe preservation strategy for born-digital documents that depend on contemporaneous software for access (Rothenberg, 2000). Yet little has been written about the contextual knowledge required to successfully use such software. The approach we advocate is to preserve necessary contextual information through scripts designed to control the legacy enviro...
متن کاملEvaluating Assisted Emulation for Legacy Executables
Access to many born-digital materials can only be accomplished economically through the use of emulation where contemporaneous software is executed on an emulated machine. For example, many thousands of CD-ROMs have been published containing proprietary software that cannot be reasonably recreated. While emulation is proven technology and is widely used to run both current and obsolete versions...
متن کاملVerifying Emulation of Legacy Mission Computer Systems
Processor obsolescence is a serious maintenance problem for long-lived embedded control systems. A practical solution is to interpose an emulator program between the ‘legacy’ software and a replacement processor, so that the old code can be reused on the new machine. Unfortunately, no verification techniques exist for proving that the resulting system preserves the original system’s functional ...
متن کاملSteganography for Executables
Steganography embeds a secret message in a seemingly innocuous cover-object. This paper presents a framework for steganography with executables as cover-objects built on top of an existing binary rewriter. Executables differ significantly from previously explored coverobjects, we thus first identify the cover-specific redundancies that can be used to embed a secret message. Techniques are then ...
متن کاملCertification Criteria for Emulation Technology in the Australian Defence Force Military Avionics Context
Emulation technology promises to provide a means of addressing obsolescence issues in legacy computer processors in the military avionics domains. It has also been suggested that such technology might apply to safety critical and safety related systems in these domains. Numerous companies either have developed or are developing software components that are capable of emulating different legacy ...
