plaintext

[′plān‚tekst]
(communications)
The form of a message in which it can be generally understood, before it has been transformed by a code or cipher into a form in which it can be read only by those privy to the secrets of the cipher.
(computer science)
Data that are to be encrypted.

plaintext

(cryptography)
A message before encryption or after decryption, i.e. in its usual form which anyone can read, as opposed to its encrypted form ("ciphertext").

plaintext

(1) Text that contains no formatting. See text email.

(2) Text that has not been encrypted. Also called "cleartext," plaintext is readable by any text editor such as Notepad and word processors that import ASCII text (almost all do). Contrast with "ciphertext," which is text that has been encrypted. See cryptography.


Plaintext Becomes Ciphertext
In this secret key example, the XOR operator is used to turn plaintext into ciphertext and then back to plaintext again. In practice, XOR is not used quite as simply as this. It is used in combination with different techniques and other ciphers to provide the complete encryption algorithm.

3) The sender uses formula (48) to encrypt the plaintext steam M, obtaining a ciphertext C = E(M, P).
The tests were performed by changing the plaintext bit from "11" to "10" and from "FF" to "F0".
RSA performs encoding by raising each element in a numerically coded version of a plaintext message to the pub power ([mod.
Data in Table 1 show that the correlation coefficient is very great between adjacent pixels of the plaintext image, and the correlation coefficient is almost close to 1.
Together, the moves and annotations relate the story to the chess board; which is what a key does for a plaintext and a ciphertext.
Playfair is multiple letter encryption cipher, in which diagrams in the plaintext are treated as single units and these units are translated into cipher text diagrams.
Once you've downloaded PlainText from the iTunes store and opened it up, you should see a screen similar to the one on the right.
2]AM is very effective in local authentication, replay attack resistance, stolen verifier attack resistance, session key creation, mutual authentication to prevent server spoofing attack, known plaintext attack resistance and message alteration attack resistance.
They also critically examined different type of DNA steganography systems, and showed that in certain cases such schemes may not cryptographically secure, and can be broken with certain assumptions on the entropy of the plaintext messages.
2) Preprocessing Plaintext: This Algorithm performs transformation on plaintext so as to suitable to give as ANN input
Some projects described include an artificial dendritic cells algorithm for online break-in fraud detection, a biometric-based security system for plaintext e-mail messages, and an e-performance management system used in federal government organizations of the United Arab Emirates.
With a onetime pad, there are as many bits in the key as in the plaintext.
