SD-AREE-I Cipher: Amalgamation of Bit Manipulation, Modified VERNAM CIPHER & Modified Caesar Cipher (SD-AREE)
This paper presents a new combined symmetric key cryptographic technique, which is generally an amalgamation of Bit Manipulation, generalized Modified Vernam Cipher, Single Bit Manipulation and Modified Caesar Cipher. The technique proposed here is basically an advanced and upgraded module of SD-AREE cryptographic method, which is based on Modified Caesar Cipher along with Bit Manipulation and ...
متن کاملEnhancing the security of caesar cipher substitution method using a randomized approach for more secure communication
Caesar cipher is an ancient, elementary method of encrypting plain text message into cipher text protecting it from adversaries. However, with the advent of powerful computers, there is a need for increasing the complexity of such techniques. This paper contributes in the area of classical cryptography by providing a modified and expanded version for Caesar cipher using knowledge of mathematics...
متن کاملAn Advanced Combined Symmetric Key Cryptographic Method using Bit Manipulation, Bit Reversal, Modified Caesar Cipher (SD-REE), DJSA method, TTJSA method: SJA-I Algorithm
In this paper, the authors propose a new combined symmetric key cryptographic method, SJA-I, which basically has four steps: Firstly, each byte is broken into its equivalent binary format and then single bit manipulation is executed on that; secondly Modified Caesar Cipher technique (SD-REE) and TTJSA cipher algorithm are applied on the data (message) randomly, which depends on the key provided...
متن کاملFast T2 mapping with multiple echo, Caesar cipher acquisition and model-based reconstruction.
PURPOSE Fast, quantitative T2 mapping is of value to both clinical and research environments. However, many protocols utilizing fast spin echo (FSE) pulse sequences contain acceleration-induced artifacts that are compounded when fitting parameter maps, especially in the presence of imperfect refocusing. This work presents a B1 -corrected, model-based reconstruction and associated Cartesian FSE ...
متن کاملImplementation of Caesar Cipher and Chaotic Neural network by using MATLAB Simulator
Today as every information is in form of electronic data. The security of data is increased due frequent attacks by outsiders. So, there is a need to secure this information by using cryptography. Cryptography is a technique to make information unreadable for unauthorized users. Various algorithms are used for cryptography to convert original information. In this paper we are going to implement...
