Section: Cryptography

The Public-Key Infrastructure (PKI) is intended to offer a means of providing security to messages and transactions on a grand scale. The need for universal systems to support ecommerce,
secure transactions, and information privacy is one aspect of the issues being addressed with PKI. A PKI can be used to protect software.

A: Transport encryption would protect data that is sent between two entities. It would not be able to protect use of software.
B: IPSec protect data that is sent between two entities through encryption. It would not be able to protect use of software.
C: Nonrepudiation is a means of ensuring that transferred data is valid. Nonrepudiation is not a way to protect software.
Nonrepudiation means to ensure that a transferred message has been sent and received by the parties claiming to have sent and received the message.
