The security level of a private key system depends on the
number of:
A. encryption key bits.
B. messages sent.
C. keys.
D. channels used.
Answer / guest
Answer: A
The security level of a private key system depends on the
number of encryption key bits. The larger the number of
bits, the more difficult it would be to understand or
determine the algorithm. The security of the message will
depend on the encryption key bits used. More than keys by
themselves, it's the algorithm and its complexity, which
make the content more secured. Channels, which could be open
or secure, are the mode for sending the message.
