Reverse Engineering can be defined as the process wherein a
device’s, object’s, or system’s technological principles are discovered by
analyzing its operation, function, and structure. It often refers to detaching
something, say- a software program, electronic equipment, or mechanical device
and carrying out the analysis of its workability in detail. This is done in
order to manufacture a new program or device which performs the same function
without doubling anything from original.
Motivation: Reasons behind the emergence of
reverse engineering include interoperability, lost documentation which means
loss or non-existence of documentation of the concerned device, product
analysis, security auditing, exclusion of protection of copy, circumvention of
restrictions regarding access, and fraud.
?Reverse Engineering’ of ?mechanical devices’ :
With the ever-increasing popularity of CAD, ?reverse engineering’ has proven to
be a blessing for creation of ?3D virtual model’ of the on hand physical part
to be used in 3D CAE, CAM, CAD and many other soft wares. The measuring of
physical object can be done by making use of ?#D scanning technologies’ such as
computed tomography, ?structured light digitizers’, laser scanners, and CMMs.
The data that is measured usually gets represented as ?point cloud’. It is
devoid of topological information. That’s why, the processing and modelling
takes place into usable format like a ?triangular faced mesh’, CAD model, or a
collection of surfaces of NURBS. Applications such as Polyworks, Image ware,
Geomagic, or Rapidform are used for processing the ?point clouds’ into the
formats that can be used in applications like 3D CAE, CAM, CAD or
visualization.
?Reverse Engineering’ of ?software’ : The term ?reverse engineering’ differs from
person to person when applied in terms of software. As per the research
conducted by Cross and Chikofsy, reverse engineering can be referred to as the
process that involves the analysis of the subject system for creating its
representation at the higher level. This level might be called the ?level of
abstraction’. As far as software is concerned, reverse engineering can be
described as an examination process only. There is no modification from the
software point of view. The use of ?software anti-tamper technology’ takes
place in order to deter reengineering and reverse engineering of the
software-powered systems and proprietary software.
Two major reverse engineering types exist in the present
scenario. In the first type, source code is available, but program’s greater
level aspects are poorly documented or invalidated. In the second type, source
code does not exist. Any efforts made in this direction would be termed as
?reverse engineering’. The 2nd use is that which majority of people
know. ?Reverse Engineering of software’ is implied at making use of ?clean room
design’ technique for avoiding infringing copyrights. In today’s world, around
95% of reverse engineering consists of ?reverse engineering of software’.
On the other hand, ?black box testing’ in ?software
engineering’ has many similarities to reverse engineering. The tester normally
possesses the API. However , their main goal is to locate undocumented features
and bugs by smashing the products from the outside. This process is used for
customizing the embedded systems as well.
