Sorry for this kind of a question, but I really like to learn and improve in cryptography. At the moment I am following online lectures from https://class.coursera.org/crypto-011 , can anyone suggest me any resources or some beginner projects or some documentation for reinforcing the information. Thanks in advance.
The course on coursera is similar to the course CS255 given in Stanford university. You can find the course homepage at CS255 course homepage. There are many homeworks and projects that you can check.
To further reinforce the information presented, read the pages suggested in the "Readings" of the course syllabus at CS255 course syllabus
