Uses two keys: one to encrypt data and one to decrypt data Show
Encryption algorithm used for the Data Encryption Standard Uses a single key to encrypt and decrypt data A digital document that verifies the two parties exchanging data over the Internet are really who they claim to be Used for verification, takes a variable-length input and converts it to a fixed-length output string Used to find the same hash value for two different inputs and reveal any mathematical weaknesses in a hashing algorithm Operate on plaintext one bit at a time A structure consisting of programs, protocols, and security policies for encrypting data and uses public key cryptography to protect data transmitted over the Internet A sequence of random bits generated from a range of allowable values The use of random data alongside plaintext as an input to a hashing function so that the output is unique Which function ensures that a sender and receiver Cannot deny sending or receiving a specific message?Nonrepudiation ensures that no party can deny that it sent or received a message via encryption and/or digital signatures or approved some information. It also cannot deny the authenticity of its signature on a document.
Which of the following is a function that takes a variable length string or message and produces?A one-way hash function, also known as a message digest, is a mathematical function that takes a variable-length input string and converts it into a fixed-length binary sequence that is computationally difficult to invert—that is, generate the original string from the hash.
Which of the following is the process of converting ciphertext back into plaintext?decryption – the process of reverting ciphertext to plaintext (occasionally 'decipherment').
What is encryption and description?Encryption is the process of translating plain text data (plaintext) into something that appears to be random and meaningless (ciphertext). Decryption is the process of converting ciphertext back to plaintext. To encrypt more than a small amount of data, symmetric encryption is used.
