Ahmed, H. M., Jassim, R. W..  2020.  Distributed Transform Encoder to Improve Diffie-Hellman Protocol for Big Message Security. 2020 3rd International Conference on Engineering Technology and its Applications (IICETA). :84—88.

Man in the middle Attack (MIMA) problem of Diffie-Hellman key exchange (D-H) protocol, has led to introduce the Hash Diffie-Hellman key exchange (H-D-H) protocol. Which was cracked by applying the brute force attack (BFA) results of hash function. For this paper, a system will be suggested that focusses on an improved key exchange (D-H) protocol, and distributed transform encoder (DTE). That system utilized for enhanced (D-H) protocol algorithm when (D-H) is applied for generating the keys used for encrypting data of long messages. Hash256, with two secret keys and one public key are used for D-H protocol improvements. Finally, DTE where applied, this cryptosystem led to increase the efficiency of data transfer security with strengthening the shared secret key code. Also, it has removed the important problems such as MITM and BFA, as compared to the previous work.

Moe, Khin Su Myat, Win, Thanda.  2018.  Enhanced Honey Encryption Algorithm for Increasing Message Space against Brute Force Attack. 2018 15th International Conference on Electrical Engineering/Electronics, Computer, Telecommunications and Information Technology (ECTI-CON). :86—89.
In the era of digitization, data security is a vital role in message transmission and all systems that deal with users require stronger encryption techniques that against brute force attack. Honey encryption (HE) algorithm is a user data protection algorithm that can deceive the attackers from unauthorized access to user, database and websites. The main part of conventional HE is distribution transforming encoder (DTE). However, the current DTE process using cumulative distribution function (CDF) has the weakness in message space limitation because CDF cannot solve the probability theory in more than four messages. So, we propose a new method in DTE process using discrete distribution function in order to solve message space limitation problem. In our proposed honeywords generation method, the current weakness of existing honeywords generation method such as storage overhead problem can be solved. In this paper, we also describe the case studies calculation of DTE in order to prove that new DTE process has no message space limitation and mathematical model using discrete distribution function for DTE process facilitates the distribution probability theory.
