c) You are in charge of designing a secure Internet Banking System. While designing the system, you need to consider several aspects of information security, such as: i) user authentication, ii) bank server authentication, iii) distribution of the public key (if using an asymmetric cipher), iv) distribution of the symmetric key (if using a symmetric cipher), v) confidentiality of the communication between the user and the bank server, vi) integrity of the communication between the user and the bank server, vii) non-repudiation. To address these design goals, you may need to use a combination of different types of cryptographic/security primitives. Symmetric Asymmetric Message authentication Digital encryption signatures exchange Hash Public key Key Digital Certificate Ciphers functions cades (MAC) Stream Block ciphers ciphers Figure 3: Basic cryptographic building blocks Select appropriate primitives that you propose to address each of the above security goals and provide necessary…
