Encryption has four main purposes, which provide essential elements of information security. Based on this, associate each of these objectives, which are found in the left column, with its meaning. (1) confidentiality (2) authentication (3) Integrity (4) Don't repudiate ( ) The recipient must be able to determine whether the message has been altered during transmission. ( ) Only the authorized recipient should be able to extract the contents of the encrypted message ( ) It must not be possible for the sender to deny sending the message. ( ) The recipient must be able to identify the sender and verify that he himself sent the message. The correct order is: A) 1 – 3 – 4 – 2 B) 3 – 1 – 4 – 2 C) 1 – 4 – 2 – 3 D) 3 – 2 – 4 – 1 E) 3 – 1 – 2 – 4

A government agency comes to the conclusion that it must use encryption in order to safeguard the communication that takes place between itself and its overseas counterparts. It is determined to design a proprietary cryptographic algorithm for this reason during a meeting with its counterparts, and this will be done in order to: Is there a justification for this choice. What risks are being taken?
To protect communication between itself and its abroad counterparts, a government agency determines that encryption is required. For this reason, it is decided at a meeting with its competitors to develop a proprietary encryption technique.Is this decision justifiable? What risks are being tolerated?
To what extent does a "Cryptographic Technique" use the "Principle of Confidentiality" to ensure the security of our data?
Asymmetric encryption methods, such as those used in public key cryptography, provide many benefits. What is the process by which the public key encryption is implemented?
A government department decides it needs to use encryption to protect communication between itself and its international counterparts. At a meeting with its counterparts, it is decided to develop a proprietary cryptographic algorithm for this purpose. a) Is this decision justifiable? b) What risks are being taken?
Explain the concept of "fully homomorphic encryption" and its role in privacy-preserving computation on encrypted data.
4. An encryption scheme is unconditionally secure if the ciphertext generated does not contain enough information to determine uniquely the corresponding plaintext, no matter how much cipher text is available. i) True ii) False
The usage of public-key cryptography and other asymmetric encryption methods is highly recommended. The use of public keys in cryptography is one such use.
It is prudent to utilise asymmetric encryption techniques, such as those found in public-key cryptography. Proof of this is the use of public keys in the field of cryptography.
Is it possible to encrypt not only the data but also the connection from starting point to finishing point? What are some of the benefits that come from acting in this manner? Could you give me an example of a circumstance when it would be beneficial to make use of encryption technology?
The challenge-response authentication mechanism is a security protocol that verifies the identity of a user or system. It operates by requiring the user to provide a response to a challenge posed by the system. The challenge is typically a random string of characters generated by the system and sent to the user. The user then computes a response based on the challenge and a secret key known only to the user and the system. If the response matches the expected value, the user is authenticated and granted access. This mechanism is commonly used in various applications, including online banking, email services, and network security systems. The specific features of this method that contribute to its enhanced security in comparison to a conventional password-based approach are not readily apparent.
Is it possible to encrypt both the data and the connection from beginning to end? What are the advantages of doing this? Please provide an example of a situation in which the use of encryption might be advantageous.
