IT 279 UNIT 4 ASSIGNMENT 2 1. Which statement is true of symmetric cryptography? A. Symmetric cryptography is faster than asymmetric cryptography. B. Symmetric cryptography uses different keys to encrypt and decrypt messages. C. Symmetric cryptography does not require a secure mechanism to properly deliver keys. “The major strength of symmetric key cryptography is the great speed at which it can operate. Symmetric key encryption is very fast, often 1,000 to 10,000 times faster than asym...
