Information and security are two factors that are interdependent. To reach its relevance, information security has evolved into a global issue that necessitates a variety of tools, regulations, and assurance of technologies against any relevant security concerns. Thousands of writers are being drawn to the internet flood, which offers a flexible means of disseminating online…

The usage of the internet is increasing over the world these days, making security a big worry for consumers. Any information that is saved on a digital platform is referred to as data. The safeguarding of data is what security is all about. Data security refers to the use of digital safeguards to secure data…

The paper proves that an odd composite integer N can be factorized in O ((log2N)4) bit operations if N = pq, the divisor q is of the form 2au +1 or 2au -1 with u being an odd integer and α being a positive integer and the other divisor p satisfies 1 < p <…

In cryptography, the RC4 protocol is the most widely used. The goal of this project is to investigate the efficient design of the RC4 stream cypher and to propose an efficient cypher architecture. The loop unrolling and pipeline concepts were used to generate two RC4 key stream bytes every clock cycle. The design is compared…

Fiber optic communication has become increasingly popular in recent decades due to its several advantages over traditional cable connection. Fiber optic connectivity enables for a download speed of 100 Mb/s and a fast upload speed with little latency. Despite the fact that fibre optics can send large volumes of data across long distances quickly, it…

For their own vested interests, hackers are frequently willing to hack secret documents. Establishing a secure relationship between the secret message and image quality is the most difficult task. To prevent illegal attacks by an unknown person, the suggested approach combines cryptography and visual steganography techniques. Image and message security will be enabled by this…

The studies on Wiener’s attack on RSA with small deciphering exponents led to the refinement of attack bounds on the deciphering exponent in the paper “Revisiting Wiener’s Attack – New Weak Keys in RSA” by Subhamoy Maitra and Santanu Sarkar. Further in the paper “ Extending The Wiener’s Attack to RSA-Type Cryptosystem” by R. G.…

Cryptography is of great importance to people of all generations and is presented as an application of mathematical sciences. On the other way, giving mathematics as basics of cryptography reduces the application of mathematical insights to the message “Cryptography contains Mathematics”. This paper introduces cryptography from Caesar Cipher to Public Key Cryptography with simple examples.…
