- Is it feasible to utilise software on a desktop computer to produce safe secret keys for use in cryptographic protocols?In order to protect communications between itself and its abroad peers, a government agency decides to adopt encryption. During a discussion with its equivalents, it was decided to build a proprietary cryptographic algorithm in order to: Are there any reasons why this decision was made. What dangers are involved?Is there desktop software that can reliably generate keys for use in cryptographic protocols?
- 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. Is this decision justifiable? What risks are being taken?Perform the Encryption and then the Decryption for the Hill Cipher where the Plain text: "POH" and the key is: "GYBNQKURP".For simplicity, let's say a Vigen'ere cypher is used to scramble a long piece of text, and the same string occurs many times in the ciphertext. Describe how you plan to use this data to determine the key's length.
- Think about the case when the same string of text is encrypted using the Vigen'ere cypher and the ciphertext is commencing at many different positions. Include a method for determining the key's length using this data.Calculate H(K), H(M) and H(C) and the unicity distance for the following cryptographic system:First encrypt your plaintext using(a) a Vernam cipher with key lengths 5 and 7.and then encrypt the cyphertext by(b) 2 x 2 Hill cipher mod 29The cypher system is the combined cypher of (a) and (b).What is the absolute bare minimal number of keys that must be utilised when implementing cryptography that relies on public keys?
