LECTURE 3: Modern cryptography

The topic covered in this lecture are:

• Modern cryptography algorithm
• Block and stream
• DES
• AES
• MAC
• Digital Signature, RSA

DES
* Provides a high level of security
* The security depends on keys, not the secrecy of the algorithm
* The security is capable of being evaluated
* The algorithm is completely specified and easy to understand
* It is efficient to use and adaptable
* Must be available to all users
* Must be exportable
