Which of the following statements is TRUE about data encryption as a method of protecting data?

Kerberos depends upon what encryption method?

Public Key Infrastructure (PKI) uses asymmetric key encryption between parties. The originator encrypts
information using the intended recipient’s “public” key in order to get confidentiality of the data being sent. The
recipients use their own “private” key to decrypt the information. The “Infrastructure” of this methodology
ensures that:

Where parties do not have a shared secret and large quantities of sensitive information must be passed, the
most efficient means of transferring information is to use Hybrid Encryption Methods. What does this mean?

What is a characteristic of using the Electronic Code Book mode of DES encryption?

What algorithm was DES derived from?

The RSA algorithm is an example of what type of cryptography?

In what type of attack does an attacker try, from several encrypted messages, to figure out the key used in the
encryption process?

Which one of the following authentication mechanisms creates a problem for mobile users?

Which of the following is the most costly countermeasure to reducing physical security risks?
