Final answer:
A transport encryption protocol is used to secure data confidentiality and integrity while it is transmitted across a network, preventing unauthorized access or interception.
Step-by-step explanation:
A transport encryption protocol is designed to protect the confidentiality and integrity of data as it travels across a network. This includes data such as personal information, passwords, and financial transactions.
Transport encryption works by encrypting data before it leaves the sender's device and then decrypting it once it reaches the recipient's device. This process ensures that even if the data is intercepted during transmission, it would be unreadable to the interceptor without the proper decryption key. Popular transport encryption protocols include Secure Sockets Layer (SSL), its successor Transport Layer Security (TLS), and Secure Shell (SSH).
These protocols are crucial in protecting sensitive information from being accessed by unauthorized parties, thus preserving the privacy and security of users' data during online interactions.
