What encryption standard is currently recommended by NIST?Advanced Encryption Standard (AES)
NIST announced the approval of FIPS 197, Advanced Encryption Standard in 2001. This standard specifies the Rijndael algorithm as a FIPS-approved symmetric-key algorithm that may be used by U.S. Government organizations (and others) to protect sensitive information.
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.
What is an encryption algorithm?An encryption algorithm is the method used to transform data into ciphertext. An algorithm will use the encryption key in order to alter the data in a predictable way, so that even though the encrypted data will appear random, it can be turned back into plaintext by using the decryption key.
