QUESTION 75 A system encrypts data prior to transmitting it over a network, and the system on the other end of the transmission media decrypts it. If the systems are using a symmetric encryption algorithm for encryption and decryption, which of the following statements is true? A symmetric encryption algorithm uses the same key to encrypt and decrypt data at both ends of the transmission media A symmetric encryption algorithm uses different keys to encrypt and decrypt data at both ends of the transmission media A symmetric encryption algorithm does not use keys to encrypt and decrypt data at both ends of the transmission media A symmetric encryption algorithm is an insecure method used to encrypt data transmitted over transmission media
