- Using asymmetric encryption methods, like those used in public-key cryptography, is a good idea. This is shown by the use of public keys in cryptography.Using asymmetric encryption methods, like those used in public-key cryptography, is a good idea. This is shown by the use of public keys in cryptography.1. Asymmetric Encryption and Message Authentication: a) The primitive root of a prime number is the basic principle of Diffie-Hellman. i) Is 3 the primitive root of 11? Show the proof with your calculation. ii) What are the important criteria for selecting a prime number in cryptography? Is 11 a good choice for such a purpose? b) Find the parameters stated using the Diffie-Hellman methods, given the user A and B shared a prime number and its primitive root of 23 and 5, respectively. i) If user A public key value is 8, find the A’s private key. ii) If user B public key value is 19, what is the common secret key? c) In the following scenario, we will compare the security services that are given by digital signatures (DS) and message authentication codes (MAC). We assume that James can read all messages send from Chan to Badrul and the other way around, too. James has no knowledge of any keys but the public one in the case of DS. State whether and…Utilizing asymmetric encryption methods, such as those used in public-key cryptography, is something that will prove to be beneficial to the user. An illustration of this would be the use of public keys in cryptography.
- Does desktop computer software exist that can reliably create secret keys for use in cryptography protocols?Is the use of encryption going to turn into a part of the usage of biometrics at some point in the future? How significant is the role that cryptography plays in the evolution of biometric technologies?11. A ---------- consists of a set of cryptographic algorithms together with the key management processes that support use of the algorithms in some application context.
- Is it necessary to employ a large number of keys when constructing cryptography that makes use of public keys, or might a smaller number suffice?Outline the procedure for a challenge-response authentication method. Intuitively, it is unclear how this approach improves upon the status quo of using passwords.Give an example of each type of authentication and the risks that come with it. Then give an answer.Bob compares a password that has been hashed to a database that also has hashes.Bob looks at what's in a database and compares it to a double-hashed password.
- Public-key cryptography, or another kind of asymmetric encryption, is strongly suggested. Proof of this may be seen in the use of public keys in cryptography.Can authentication accomplish anything?Choosing an authentication method involves several factors.Encryption - what is it and how does it work? Distinguish between private and public key encryption by providing definitions and examples. How is sender authentication and secrecy provided by public-key cryptography?
