New possibilities in the pixel-based cryptography (6th International Congress on Scientific Research August 18-20. 2023, Ankara by IKSAD Institute)
Vezércikk: 2023. November (MIAU No. 303.)
(Előző: MIAU No. 302.)
Keywords: cellular automata, genetic algorithms, binary/numeric pixel-value transformations, binary Caesar-code-like ciphers, de/coding of pictures (hand-writing messages)
Abstract: History: The trans-institutional MY-X research team produced till now more qualitative ciphering solutions in order to demonstrate
the quasi unlimited possibilities of transformations being capable of hiding information:
e.g., https://miau.my-x.hu/miau2009/index.php3?x=e0&string=cipher, https://miau.my-x.hu/miau2009/index.php3?x=e0&string=aesthetic,
https://miau.my-x.hu/miau2009/index.php3?x=e0&string=jav%C3%ADt%C3%B3kulcs
Background and benchmarks: The well-known Caesar-codes define a small combinatorial space – easy to identify it.
The Caesar-codes are always focusing on letters/numbers/characters. But the digitalisation represents these characters in form of pixel-matrices.
Dot-matrix-fonts in dot-matrix-displays let flash certain pixels for a particular letter. Therefore, digital/binary Caesar-codes could be created
if the active and passive pixels (see 1;0) would be modified – in a rule-based form.
Highlighted details: The focusing on the pixels of the digitalized letters makes it possible to involve new transformations into the coding-decoding processes:
e.g., pixels for one letter or even for arbitrary letters (see an entire picture – where in case of hand-writing-messages
the recognition module can also be part of the decoding process) can be transformed into a circle in different ways,
where the Caesar-code-like shifting can be interpreted immediately. Not only simple shifting-patterns can be defined, but also rules for cellular automata.
These rules can even be so complex, that the decoding is quasi impossible, or this becomes a new combinatorial challenge.
The digital representation of letters can also be seen as a door to the genetic algorithms with their specific transformations (like mutation, crossing, etc.).
Patterns for binary pixel-values can be created based on different series like Fibonacci or even specific randomized inputs like pi. Digitalized pixel-values can have numeric contents
(like in case of grey-scale-pictures). With these numeric values, new (quasi arbitrary) transformations can be initialized.
The above-mentioned possibilities are not direct concurrent approaches for the well-known cryptographical solutions (see private/public keys),
where the quantities become qualities (in case of limited computational capacities).
Future aspects: The pixel-oriented approaches can rather be compared to the old/rare native languages used e.g., in the second world war e.g., by Americans e.g., against Japanese
(c.f. code talkers). Therefore, the above-presented pixel-based approaches can be used in case of specific demands:
communication between business partners, agents. These qualitative techniques make possible to hide graphical plans as a kind of non-figurative picture.
Specific watermarks can also be created based on pixel-transformations. These solutions can be combined with quasi arbitrary other effects
(c.f. letter-statistic-homogenisation, blurred contours of letters, more substitutions for one original input, etc.).
