Cryptography is the art of writing secret code so that no one apart from the intended recipient could read it. Authorization is not one of the four primary objectives of cryptography. The four primary objectives of cryptography are Confidentiality, integrity, authentication, and irrevocability.

Cryptography helps to keep vital information confidential; messages are concealed by encoding it, making it accessible for the receiver to read-only. Message integrity in the sense that the message received is the same as the one sent, digital signatures are created to protect malicious alteration, the receiver creates the same technique to compare the messages.

The authentication of data is accomplished by using a digital certificate; when the user can prove their identity to another, it shows the authentication of the message.

The correct answer to this question is No. Authorization is not one of the fundamental goals of cryptography. The following are the four fundamental goals:
1. Confidentiality: This goal makes sure that the data stays private when it is resting. Examples of this is data that is on a flash drive or a disk

2. Integrity: This goal ensures that the data does not have any changes that are not authorized

3. Authentication: This goal is used to ensure that the identity of the users is accurate.

4. nonrepudiation: This goal is used to alert the recipient that the message or data being shared is truly from the messenger

Yes, it is, and cryptography aims to focus on four areas in both theory and practice sufficiently. The first, confidentiality is the basic security service delivered by cryptography. It is a security provision that keeps the data from an unauthorized individual. It is at times referred to as privacy or secrecy.

Data integrity is second. It is a security service that handles recognizing any changes to the data. An unauthorized entity may alter the information. It provides a way to uncover whether data is unbroken or not since it was last created, transferred, or stored by an authorized user.

The third is authentication, which offers the originator's documentation, which verifies to the receiver that the data obtained has been sent only by an identified and verified sender. The fourth is nonrepudiation, a property that is best in situations where there is the possibility of a quarrel over the exchange of data.

No. When it comes to cryptography, the primary goal is to make sure that all of the four areas are being addressed. This means that in theory and practice, the message content should be secure. One of the main goals of cryptography is confidentiality. This is the first primary objective and this can be achieved by making sure that messages are correctly encrypted.

Data integrity, on the other hand, is achieved through hashing functions. Authentication would become available when asymmetric cryptography is done. Finally, non−repudiation will normally become available when getting proper cryptographic digital signatures are done properly.

The right answer to this question is No. One of the primary objectives of cryptography, similar to the one given in the question, is Authentication and not authorization. The main idea of cryptography is to ensure that certain information only gets to those who are supposed to read and process it.

Apart from authentication, the other three objectives of cryptography are Non-repudiation, Data Integrity, and Confidentiality. Non-repudiation, one of the objectives of cryptography, ensures that the origin of any sent message cannot be denied by anybody.

Confidentiality ensures that only authorized recipient(s) can have access to the content of the cypher. Data integrity allows the recipient of the message to know if there was any alteration during transmission. Authentication, the last of the security features of cryptography, allows the recipient to verify and identify the sender. The idea is to determine if a message came from a genuine source.

No, it is not Authorization. A fundamental goal of cryptography is to adequately address four areas in both theory and practice. Confidentiality is normally achieved by encrypting the message content, data integrity is achieved through cryptographic hashing functions, authentication is achieved through the use of asymmetric cryptography, and non-repudiation is normally achieved through the use of cryptographic digital signatures.
