Watch the encryption videos. Cryptography is the mathematical manipulation of information that prevents the information of the organization from being disclosed or altered. Discuss the encryption steps, private keys, public keys and digital certificates. How does the video on Cryptography interact with Smart Data? On page 196, you will find the data reference model. What are the three standardization areas? On page 197, define the three dimensions of Smart Data. Investigate cryptography and information security. Research some of the key topics in this domain of Enterprise Architecture. Why is it important to the well being of the organization? Define confidentiality, integrity, authentication and nonrepudiation. Why would a Digital envelope be important from a Smart Data perspective? Why is a symmetric (single) key encrypted with assymetric (two) keys (private and public) and how does this process contribute to the smart data philosophy? Why is the receiver's public key used to encrypt the symmetric key and the receiver's private key used to decrypt the symmetric key? Write a one page summary with reference and written in scientific method.
