transport protocol can provide an application with one or more security
services. For example, in the sending host, a transport protocol can encrypt all data
transmitted by the sending process, and in the receiving host, the transport-layer
protocol can decrypt the data before delivering the data to the receiving process.
Such a service would provide confidentiality between the two processes, even if the
data is somehow observed between sending and receiving processes. A transport
protocol can also provide other security services in addition to confidentiality,
including data integrity and end-point authentication,
services. For example, in the sending host, a transport protocol can encrypt all data
transmitted by the sending process, and in the receiving host, the transport-layer
protocol can decrypt the data before delivering the data to the receiving process.
