Question9Max. score: 2.00To enhance non-repudiation and integrity, you plan to implement digital signatures for documents and software releases. The selected cryptographic technique must convincingly verify the authenticity of digital messages or documents, provide a way to verify the authenticity and integrity of messages, ensure that a message or document has not been altered, and the sender is authenticated, and most importantly, be widely accepted for legal and financial documents to establish trust. Which of the following encryption algorithms best meets your requirements?RSASHA-256AESMD5

Question5Max. score: 2.00For certain applications, especially those involving direct communication between clients, you aim to ensure that data is encrypted from its point of origin to its destination, known as end-to-end encryption. The ideal encryption method must ensure intermediaries cannot access plaintext information, protect data confidentiality and integrity across the transmission path, and be commonly used in messaging apps, email, and other forms of direct communication to ensure reasonable overhead. Which of the following encryption algorithms best meets your objectives?AES with RSAECC with Diffie-HellmanRSA with HMACPGP/GPG

Question9Max. score: 2.00Next, you turn your attention to information that travels over the network, both internally and externally. Your goal is to select an encryption algorithm that ensures data integrity and confidentiality without causing significant latency. The selected method of encryption should be known for its efficiency in securing online communications, capable of encrypting data quickly to minimise latency, and usable in SSL/TLS protocols for secure web browsing, email, and VPNs. Which of the following encryption algorithms best meets your requirements?AESRSAHMACDiffie-Hellman
