Answer:
1. Confidentiality
2. Authentication
3. Integrity.
Step-by-step explanation:
The three properties of secure communications and a specific implementation of that property are as follows:
1. Confidentiality: this implies that the sender and the receiver of the message should be the ones to understand the message. To implement this is to use encryption such as cryptographic to secure the communication is confidential.
2. Authentication: this implies that both the sender and receiver of the message should be able to confirm that the person at the other end is the actual person that is supposed to be. To implement this one needs to use cryptographic techniques as well.
3. Integrity: this also implies that the message exchanged between the sender and the receiver has not been tampered with by the interceptor. To implement this so relies on cryptographic techniques.
