Info Assurance

The mathematical formula or method used to convert an unencrypted

message into an encrypted message. This sometimes refers to the programs that enable

the cryptographic processes.

• Decryption
• Algorithm

• Hashing
• Encoding

An encryption method that involves converting plaintext to ciphertext

one bit at a time.

• Bit stream cipher

• symmetric key encryption
• hash function
• block cipher

An encryption method that involves dividing the plaintext into blocks or

sets of bits and then converting the plaintext to ciphertext one block at a time.

• Public key encryption
• Stream cipher
• Block cipher
• Hash function

When used as a verb, the transformation of the individual components

(characters, bytes, or bits) of an unencrypted message into encrypted components or vice

versa (see decipher and encipher); when used as a noun, the process of encryption or

the algorithm used in encryption, and a term synonymous with cryptosystem.

• Cipher

• Hashing
• Encoding
• Decryption

The unintelligible encrypted or encoded message resulting

from an encryption.

• Ciphertext or cryptogram

• plaintext
• hash
• key

The process of converting components (words or phrases) of an unencrypted

message into encrypted components.

• Decryption
• Compression
• Transmission
• Code

Convert to plaintext.

• Decipher

• Convert to JSON.
• Convert to HTML.
• Convert to binary.

The process of converting an encoded or enciphered message (ciphertext)

back to its original readable form (plaintext).

• Decryption
• Encryption
• Encoding
• Hashing

To encrypt.

• Use a random number generator to create a password.
• Store data in plain text for easy access.
• Use a simple substitution cipher without a key.
• Encipher

The process of converting an original message (plaintext) into a form that

cannot be used by unauthorized individuals (ciphertext).
