Which of the following BEST determines that complete
encryption and authentication protocols exist for protecting
information while transmitted?
A. A digital signature with RSA has been implemented.
B. Work is being done in tunnel mode with the nested
services of AH and ESP
C. Digital certificates with RSA are being used.
D. Work is being done in transport mode, with the nested
services of AH and ESP
Answer / guest
Answer: B
Tunnel mode provides encryption and authentication of the
complete IP package. To accomplish this, the AH
(authentication header) and ESP (encapsulating security
payload) services can be nested. The transport mode provides
primary protection for the protocols? higher layers, this
is, protection extends to the data field (payload) of an IP
package. The other two mechanisms provide authentication and
integrity.
