Ah, cryptography. It’s so important to us in our every day lives and yet it has one of the longest and confusing pasts of any type of technology we use today. Encryption has been used since ancient times by generals, spies, rebels, and even politicians. The cipher is considered one ...
Both of these problems can be elegantly solved using public key cryptography. I. Encryption and decryption of data Alice wants to send a message to Bob which no one should be able to read. Alice encrypts the message with Bob's public key and sends it over. Bob receives the message and ...
Some application of difference equations in Cryptography and Coding TheoryFibonacci numbersdifference equationsencrypting and decryptingcoding and decodingIn this paper, we present some applications of a difference equation of degree k. Using such an equation, we provide an algorithm for messages encryption...
Public key generated from the private key through a method called cryptography and employ one of the many available cryptographic algorithms. Cryptographic algorithms such as AES are irreversible that is anybody can generate public keys from their private key but not vice-a-versa. AES is one of ...
When you apply a digital signature to a document, cryptography binds your digital certificate (provided after vetting the users identity) with the data being signed into one unique “fingerprint.” Just like with a real fingerprint, the cryptographic components that make up your digitally signed doc...
Cryptography relies heavily on the assumption that certain mathematical problems are hard to solve in a realistic amount of time. When looking at Public-Key (Asymmetric) Cryptography, which is what we'll be focusing on in this blog post we use the assumed existence of One-Way functions, i.e...
Stream Ciphers Vs. Block Ciphers: In this tutorial, we will learn about the key differences between stream ciphers and block ciphers in Cryptography. By Monika Sharma Last updated : May 24, 2023 The Stream ciphers and the Block ciphers both are a type of encryption technology that differs ...
Asymmetric cryptography is used in key exchange, email and web security, and cryptocurrencies, such as bitcoin. Pros and cons of asymmetric encryption The pros of asymmetric encryption include the following: Keys are never distributed or exchanged. ...
