Problem:
Question 1- Explain how the web of trust works to solve the problem of key authentication.
Question 2- What is a certificate authority (CA)? Explain why a system of CAs is better than the web of trust for e-commerce. When is the web of trust still a useful model of key authentication.
Question 3- If your credit card information is stolen on the Net, is the reason likely to be that someone broke a weak encryption code or something else?
Please can anyone help me to answer these question in detail.
