In this paper, we purpose a new symmetric substitution cipher technique using a mechanism on vowel, consonants of English language and numeric digits, which exploits the disadvantages of the symmetric substitution techniques previously known to us. Also certain new aspects of encryption and decryption ...
but when it comes to security, it is not secure. The reason behind this is its simplicity: once attacker cracks the map so he can easily decipher any message. One of the techniques used to
However, these techniques remain useful for understanding cryptography and the workings of more complex modern ciphers.
The experiment was part of a larger ongoing project in which the significance of the side-channel information is evaluated in various reverse engineering techniques. As described, the method requires from the cryptanalyst the ability to en- crypt pieces of plaintext of his own choosing; however,...
In this regard, cryptography plays an important role in the encryption of private data and information. The field of graph theory is important in a variety of domains. Graph theory, in particular, is commonly utilized as an encryption technique, as graphs can be transformed into matrices. In ...
but it is likely to have been reasonably secure, not least because most of Caesar's enemies would have been illiterate and others would have assumed that the messages were written in an unknown foreign language.[5] There is no record at that time of any techniques for the solution of simpl...
In addition to providing hardware-dependent costly and slow solutions, statistical weakness is an important disadvantage of a cryptographic TRNG that is tried to be removed with post-processing techniques. In this study, the use of Data Encryption Standard (DES) substitution-box (s-box)-based post...
The comparative results prove that the proposed technique provides more security to secret information sharing, compared to other related techniques. © 2019 IEEE 显示全文DOI: 10.1109/ICOIACT46704.2019.8938486 关键词: Cryptography; Mean square error; Signal to noise ratio; Steganography; Embedding ...

We set out to build a public key cryptosystem by repeatedly substituting for variables in multivariate polynomials and simplifying the results to conceal the substitution process. There seems, however, to be no way to build such a system that is both secure and has a public key of practical si...
