A chosen plaintext attack is an attack where the cryptanalyst is able to define his own plaintext, feed it into the cipher, and analyze the resulting ciphertext. Mounting a chosen plaintext attack requires the cryptanalyst to be able to send data of his choice into the device which is doing the encryption, and it requires …
Computer worms are programs that reproduce, execute independently, and travel across network connections. The key difference between a virus and worm is the manner in which each reproduces and spreads. A virus is dependent upon the host file or boot sector and the transfer of files between computers to spread, whereas a computer worm can …

In a symmetric cipher, both parties must use the same key for encryption and decryption. This means that the encryption key must be shared between the two parties before any messages can be decrypted. Symmetric systems are also known as shared secret systems or private key systems. Symmetric ciphers are significantly faster than asymmetric ciphers, …
Substitution and transposition ciphers are two categories of ciphers used in classical cryptography. Substitution and transposition differ in how chunks of the message are handled by the encryption process. Substitution ciphers Substitution ciphers encrypt plaintext by changing the plaintext one piece at a time. The Caesar Cipher was an early substitution cipher. In the Caesar …
