Question

SIPRNET tokens contain three individual public key infrastructure certificates. These certificates are used for all of the following actions EXCEPT:

a) Authentication
b) Encryption
c) Digital signatures
d) Physical access control

Answer 1

SIPRNET tokens with public key infrastructure certificates are used for authentication, encryption, and digital signatures within the Secure Internet Protocol Router Network, but not for physical access control.

Step-by-step explanation:

SIPRNET tokens are used within the Secure Internet Protocol Router Network (SIPRNET) to facilitate secure communication. These tokens contain public key infrastructure certificates which have specific purposes. The certificates are used for authentication, ensuring that the person trying to gain access is who they claim to be; encryption, protecting the confidentiality of the communication by making it unreadable to unauthorized users; and creating digital signatures, which verify the sender's identity and the message's integrity. However, these certificates are not used for physical access control, which might involve using a physical token or badge to gain entry to secured spaces.
