Cryptography and Linguistics. A research on Linguistic cryptosystems.

This minor research paper details the algorithm of encoding a text using linguistic knowledge.

Let’s take a function f:A → B , where A is the collection of plain text words, and B is the collection of the encrypted words. We will take for each word in A, a word y from another language. This way “this” is “atunci”, where “atunci” means “then” in Romanian language. The words in the Romanian language corresponding to words in A collection, form the cipher’s key.

The problem of this algorithm is that it is vulnerable to frequency attack

Importance of cryptography in software development. Usage.

Before explaining applied cryptography in software, I’ll present you general importance of cryptography and cryptanalysis. These two domains are somehow unknown or ignored by the large public and the majority of today’s inexperienced software developers. Why? Because these domains throughout history where “private” domains, they weren’t open to the public. Today, only the “masters” in math can make and proof an encryption’s security and this is a fact the software developer must understand.

I’ll continue with the importance. History was somewhat rewritten by cryptographers or cryptanalysts. In 1586 Marie Stuart was killed because of the use of a pour encryption

Modulus, a simple demonstration

I write this paper in order to prove an equation. Why? Because today, in a national maths contest, I received an exercise that could have been solved using this equation.

We know that a modular expression looks like this: a≡b(mod n) , and it is read: “a is congruent to b modulo n”.

I must prove the following: P(k): (∑α_i mod 2) mod 2=(∑α_i) mod 2 where 1≤i≤k

Research

I’m currently working on some research projects for a little conference that will be held in my school. Topics? Algorithms and the other paper: Cryptography.

I think I’ll publish them after the conference but I’m not sure I’ll do this (“intellectual property”).
