We refer to encryption and decryption algorithms as ciphers. The term cipher is also used to refer to different categories of algorithms in cryptography. This is not to say that every sender-receiver pair needs their very own unique cipher for secure communication. On the contrary, one cipher ...
Cryptography can be traced all the way back to ancient Egyptian hieroglyphics but remains vital to securing communication and information in transit and preventing it from being read by untrusted parties. It uses algorithms and mathematical concepts to transform messages into difficult-to-decipher codes...
The effectiveness of computer communication is mainly based on the security aspects. Security of information transmitted over the network is becoming tougher in spite of the availability of many cryptographic algorithms. This paper provides the various factors affecting the performance of Encryption ...
Post-quantum cryptography (PQC) refers to cryptographic algorithms designed to be secure against an attack by a powerful quantum computer. Although large-scale quantum computers are still in development, "harvest now, decrypt later" (HNDL) threats mean that organizations must start planning for a qu...
The impact on cryptography will be dramatic: most public-key algorithms currently in use are expected to be broken easily by adequate quantum computers including RSA and ECC-based public-key cryptography algorithms. The most vulnerable applications concerning quantum-computer attacks are those where asym...

Define cryptography. cryptography synonyms, cryptography pronunciation, cryptography translation, English dictionary definition of cryptography. n. 1. Computers Any of various mathematical techniques for encrypting and decrypting data in order to keep it
The system keeps the blocks in memory while waiting for complete data encryption. Some of the most important block cipher algorithms include Triple DES (Data Encryption Standard), AES (Advanced Encryption Standard), and Twofish. However, one of the risks of symmetric key encryption is that if ...
It particularly focuses on the development and application of cryptographic algorithms and protocols, including distributed ledger technology, in addressing threats to modern computer networks such as Internet of Things, smart grids, cyber-physical systems, autonomous vehicles, etc. In addition to full-...
