Now-a day e-learning is getting popularity than the traditional learning methods. Internet or Intranet is the main communication media in case of e-learning. Since, the access of Internet is very easy now-a-daysand the new generation is so much efficient about the using of Internet, so, the security plays a vital role in case of e-learning. To provide authenticity, we can apply DES algorithm during the transmission of mark sheet from developer to student, two main components of e-learning. The object oriented analysis and design of any system, makes a better understanding of the system and adjustable with the real world. The fundamental characteristic of object oriented analysis is to provide data hiding, encapsulation, data abstraction etc.We can define so many types of metrics like size metric, coupling metric, cohesion metric, inheritance metric etc. in metric analysis. Other than CK metric and MOOD metric, there are also some other object oriented metrics like Lorenz and Kidd, Harrison, Counsell and Nithi etc. We will find the values of different metrics in respect of the DES algorithm regarding the transmission of study material from developer to student.
