(a) Which of the applications discussed in this chapter such as cryptography for wireless local area network, cryptography for mobile telecommunications, cryptography for secure payment card transactions, cryptography for video broadcasting cryptography for identity cards, and cryptography for home users support a range of cryptographic algorithms, rather than recommending a fixed encryption algorithm? (b) Discuss the pros and cons of supporting a range of cryptographic algorithms in an application. (c) Why might a relatively weak' cryptographic algorithm be included amongst a set of supported cryptographic algorithms? (d) What security issues might arise from including a relatively 'weak' cryptographic algorithm in a set of supported cryptographic algorith

Cryptography involves five important concepts, integrity, confidentiality, authentication, non-repudiation, and digital signatures. Please describe the technical process, in detail, that involves sending an encrypted email from a sender to a receiver. Be sure to include and describe the technical details for each of the five concepts and the cryptography that takes place. (i.e SHA, AES, RSA, etc.). Please include in our discussion what the difference between a hashing algorithm and an encryption.
Answer the following questions: a) Symmetric key cryptography b) Asymmetric key cryptography c) How both authenticity and confidentiality is achieved while encrypting and decrypting messages using public and private keys. d) How are messages digitally signed? e) What is the function of a certification authority? f) How can we protect data while it is in use?
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?
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.
Because of recent developments in cryptanalysis, there has been a rise in the use of quantum computing. Reviewing and comprehending three to five current papers on the use of quantum computing to the process of password cracking is recommended. It would be reasonable to do a research of one to two pages on the positive and negative aspects of quantum computing.
Are there any advantages and disadvantages related with the use of symmetric encryption techniques? What kinds of things should be taken into account before deciding on a certain method of encryption to put into practice?
Public key cryptography has a number of strengths and weaknesses relative to symmetric key cryptography Please make two lists: strengths and weaknesses. In the first list (strengths) put all the things that public key does better than symmetric key (generally speaking). Include things that are not possible at all with symmetric key cryptography. In the second list (weaknesses) give some areas or respects in which public key algorithms are less advantageous than symmetric key methods.
Describe in details: Is public-key (asymmetric) encryption more secure from cryptanalysis than symmetric encryption?
How does "authenticated encryption" combine confidentiality and authentication in cryptosystems?
Public key cryptosystems are: (more than one may be true, choose all that are true) a offering a simpler way for key distribution B faster than symmetric C the preferred solution when the message we want to encrypt is very large D easily used to offer integrity E requiring advanced hardware in order to use them F easily used to offer confidentiality G marketed better than symmetric that is why people prefer them H using one key for encryption and a different key for decryption
Public-key cryptography or any other form of asymmetric encryption is recommended. Cryptography's use of public keys is evidence of this.
Asymmetric encryption algorithms, such as those used in public key cryptography, provide a number of benefits over their symmetric counterparts, as discussed above.
