Cryptology ppt
WebCryptography uses mathematical techniques to transform data and prevent it from being read or tampered with by unauthorized parties. That enables exchanging secure messages even in the presence of adversaries. Cryptography is a continually evolving field that drives research and innovation. WebApr 23, 2024 · Basically, cryptography serves as a technique for the transmission of secure messages among two or more participants. The sender leverages a specific type of key and algorithm for encryption of a message before sending it to the receiver. Then, the receiver employs decryption for obtaining the original message.
