Cryptography is a method of protecting information and communications through the use of codes, so that only those for whom the information is intended can read and process it. The pre-fix "crypt-" means "hidden" or "vault" and the suffix "-graphy" stands for "writing."

The principles of cryptography are:

1. Confidentiality: This principle ensures that the information is accessible only to those authorized to have access. It is the most common aspect of cryptography in which the information cannot be understood by anyone except the individual who is supposed to receive it.

2. Integrity: This principle refers to the assurance that the information is authentic and complete. It ensures that the information is not altered in transit through the network and that it is not intentionally tampered with during storage by unauthorized users.

3. Authentication: This principle ensures that the parties involved in communication are who they claim to be. This is achieved through validating the identities of the communicating parties before the actual communication process begins.

4. Non-repudiation: This principle ensures that a completed transaction cannot be denied afterwards. It provides proof of origin and proof of delivery to prevent the sender from denying that the message was sent and to prevent the receiver from denying the receipt of the message.

5. Access Control: This principle is used to ensure that only an authorized person can access the information. This is achieved by identifying the user and then giving the user only the rights and privileges that he or she is supposed to have.
