The What If We Programmable
Software Development Environment greatly facilitates the development
of:
-
A unique set of local tokens for each module used in the program
-
A unique set of global tokens for the entire program.
-
The software for relating the global tokens to the local tokens.
The PSDE greatly facilitates the creation of
different sets of tokens for the same product. This capability can be quite
useful relative to intellectual property protection and security requirements.
These collection
of tokens and associated modules greatly
facilitates the use of state machines in a
globally consistent manner. Benefits
include:
-
Elimination of the uncorrected errors due to logical sneak paths.
-
Better self-documentation in
all source code and source definition files.
-
Reduced maintenance costs due to improved PM/FL error reports.
-
Much greater resistance to an illegal reverse engineering effort.
The software genetics tokens can also be used to cryptographically certify data
communication. The required pseudo random generator can be defined by the tokens
that are assigned to:
-
The transmitter port.
-
The receiver port
-
The data structure.
-
The data name.
This technique has been effectively used
for communication between modules within a
program without any observable loss in
bandwidth. Also, the ease
of producing a unique set of tokens for a
specific installation can improve the
overall communication security of the
installation.
