Theory, innovations, and instruments for battling software program Piracy, Tampering, and Malicious opposite Engineering
The final decade has obvious major development within the improvement of strategies for resisting software program piracy and tampering. those strategies are essential for software program builders looking to shield very important highbrow estate. Surreptitious Software is the 1st authoritative, accomplished source for researchers, builders, and scholars who are looking to comprehend those methods, the extent of defense they have the funds for, and the functionality penalty they incur.
Christian Collberg and Jasvir Nagra compile recommendations drawn from similar components of laptop technology, together with cryptography, steganography, watermarking, software program metrics, opposite engineering, and compiler optimization. utilizing vast pattern code, they express readers easy methods to enforce safety schemes starting from code obfuscation and software program fingerprinting to tamperproofing and birthmarking, and talk about the theoretical and functional boundaries of those thoughts.
Coverage includes
- Mastering suggestions that either attackers and defenders use to investigate programs
- Using code obfuscation to make software program tougher to research and understand
- Fingerprinting software program to spot its writer and to track software program pirates
- Tamperproofing software program utilizing guards that realize and reply to unlawful changes of code and data
- Strengthening content material safeguard via dynamic watermarking and dynamic obfuscation
- Detecting code robbery through software program similarity research and birthmarking algorithms
- Using innovations to guard software program and media opposed to piracy and tampering
- Detecting software program tampering in dispensed system
- Understanding the theoretical limits of code obfuscation

As the field becomes more mainstream, we can expect journals, workshops, and conferences dedicated exclusively to surreptitious software, but this has yet to happen. The military has also spent much effort (and taxpayer money) on surreptitious software research. For example, the patent [96] held on Cousot’s software watermarking algorithm [95] is assigned to the French Thales group, the ninth-largest defense contractor in the world. S. S. Army Project Executive Offices (PEOs) and Project Managers (PMs) are now charged with executing Army and Department of Defense (DoD) AT policies in the design and implementation of their systems.
Here’s another quote from the DoD [115]: The Software Protection Initiative (SPI) is an undertaking of the Department of Defense (DoD) to develop and deploy technologies to secure special-purpose computer programs containing information critical to DoD weapon programs. SPI offers a novel approach to protecting high value computer programs. It doesn’t secure the computer or the network. Instead it empowers a single computer program to secure itself. This approach promises to significantly improve DoD’s Information Assurance posture.
In the second step, we’ve considered each basic block once, and have gathered some information. After a basic block has executed the statement x = 3, for example, it is clear that x must have the value 3. Also, if a basic block doesn’t change the value of x, then x must have the same value after the block executes as it did before. When control can flow into a basic block from two different directions and we’ve computed that x has the same value on both paths, then we can safely assume that it will always have that value at the entry to the block.
