Digitally signed messages

B.
Out-of-band messages

Forensics frequency

Explanation:
Out-of-band communication means to communicate through some other type
of communication channel. For example, if law enforcement agents were investigating
a crime on a network, they should not share information through e-mail that passes
along this network. The criminal could have sniffers still installed, thus this data
may be available to her.
