• Notion Explain

• Plaintext

  In cryptography, usually means unencrypted information pending input into cryptographic algorithms, usually excryption algorithms.

  Usually refers to data that is transmitted or stored unencrypted.

  With the adcent of computing, the term plaintext expended beyond human-readable documents to mean any data, including binary files, in a form that can be viewed or used without reqiuring a key or other decryption device.

  Plaintext is used as input to an encryption algorithm; the output is usually termed ciphertext, particularly when the algorithm is a cipher.

• Cipher

  In cryptography, a (or cypher) is an algorithm for performing encryption or decryption - a series of well-defined steps that can be followed as a procedure.

• The cryptographic transformation of data to produce ciphertext.

• Authenticated encryption

  (AE) and Authenticated Encryption with Associated Data(AEAD) are forms

  of encryption which simulataneously assure the confidentiality and authenticity of data.

• Plain encryption

  Just encryption providing confidentiality.

• Plain encryption vs Authenticated encryption

  The crucial difference between plain encryptio and authenticated encryption is that AE additionally provides authenticity, while plain encryption provides only confidentiality.
