# Cryptanalysis jobs

need someone who is good in cryptography and **cryptanalysis** as well as in matlab and maple. have to implement "differential-linear attack" on dummy structure of 4 or 8 bit cipher in matlab or maple. at the end i need a brief report and source code with comments. you have to do everything by yourself.

The requirement is to decipher a cryptogram message to plaintext. All details will be sent to interested parties if you want to know more. This project is recommended for cyber security or information security experts. No programming involve. Just explain how you did it.

I want to implement the proposed cryptanalytic algorithm utilizing the NTL library (The Number Theory Library) to get same or approximately results.

...new references (journals). The references should be related to Braids NP-hard problem, Braid Conjugacy problem and some papers which clearly support our claims that no **cryptanalysis** attacks on Braid Conjugacy problems.
Please also note that it is not important to find paper that directly talk about braids in hash functions, but It is very good to

- Differential and linear **cryptanalysis**
- Algebraic attacks
- Key schedule attacks
- Etc ..

This **cryptanalysis** assignment consists of a software implementation of an algorithm that tries to decrypt an L-symbol challenge ciphertext computed using a permutation cipher. Informally speaking, your program's goal is to find the plaintext used to compute this ciphertext within a reasonable amount of time. Specifically, your program should print on

Specifically, your program should print on screen something like "Enter the ciphertext:", obtain the ciphertext from stdin, apply some **cryptanalysis** strategy and output on screen something like "My plaintext guess is:" followed by the plaintext found by your strategy. In doing that, your program is allowed access to:
