What is the meaning of cryptosystem? The art of protecting information by transforming it (encrypting it) into an unreadable format, called cipher text.Only those who possess a secret key can decipher (or decrypt) the message into plain text.Encrypted messages can sometimes be broken by cryptanalysis, also called codebreaking, although modern cryptography techniques are virtually unbreakable. Statistical attacks are aimed at finding vulnerabilities in the hardware or operating system hosting the cryptography application. Modern cryptography has become highly complex, and because encryption is used to keep data secure, cryptographic systems are an attractive target for attackers. A public key cryptosystem is initially used to establish secure communication links (128, 134, 136, 138). In a replay attack, the malicious individual intercepts an encrypted message between two parties (such as a request for authentication) and later “replays” the captured message to open a new session. p The Government & Military Acronym / Slang cryptosystem means...
