A joint workshop on Program Protection and Reverse Engineering (PPREW) and Software Security and Protection (SSP) will be held this year, bringing two communities of interest together. Software security is a discipline that lies at the crossroads of security, cryptography, networks, software engineering, computer architecture, operating systems, and compiler design. Program protection and reverse engineering techniques both find their practical use in malware research and analysis as well as legitimate protection schemes for intellectual property and commercial software. The joint workshop will focus on how to protect software from tampering, reverse engineering, and piracy. Strongly encouraged are proposals of new, speculative ideas; evaluations of new or known techniques in practical settings; and discussions of emerging threats and problems in metrics, tools, and procedures for evaluating tamperproofing, watermarking, obfuscation, birthmarking, and protection algorithms in general. Likewise, reverse engineering of low-level constructs such as machine code or gate-level circuit definitions through static and dynamic analysis is geared to recover higher levels of abstract information to determine a program's function as well as to classify it with existing similar code (which is typically malicious). Both program protection and reverse engineering techniques are utilized for legitimate and illegal purposes. Theoretically, protection is seen as impossible in the general case but the promise of mathematically based transformations with rigorous cryptographic properties is an area of active interest. Given enough time and resources, reverse engineering and de-obfuscation is assumed to be achievable. The joint PPREW/SSP workshop will provide a discussion forum for researchers that are exploring theoretical definitions and frameworks, implementing and using practical methods and empirical studies, and those developing new tools or techniques in this unique area of security. We expect the workshop to provide exchange of ideas and support for cooperative relationships among researchers in industry, academia, and government.
