Interactive Session on Cryptography & Ad- Hoc Networking

March 24, 2017 at 10:00 AM

An interactive lecture session on 24th March,2017 Cryptography and Ad-Hoc Networking has been delivered by Prof. Dipankar Chatterjee from India Statistical Institute, Giridih, being organized and conducted by the Department of Computer Applications of NSHM College of Management & Technology, Durgapur.

 The seminar was facilitated by the Prof. (Dr.) Probir Kumar Bose, Campus Director, NSHM Knowledge Campus, Durgapur, who inaugurated the session by his very intrinsic comments on the topic which is very much relevant for present day as we are getting more inclined to online transactions. And we all need to be aware of security measures and its related technologies as a must have knowledge beside other knowledge of different professions. Following the Campus Director, acting Dean Academics Prof Biswajit Mondal added some important points regarding the essence of such knowledge sharing seminar. And finally the head of the Computer Applications Department Prof. Subhasis Datta urged the audience students to think beyond their regular syllabus and requested the guest speaker Prof. Chatterjee to take over the session and asked him enlighten the audience about the topic chosen for the seminar. It was a full packed seminar hall consisting of students and faculties.

Silence reigned the seminar hall, as Prof. Chatterjee started unveiling the ideas of Ad-hoc networking and its points of applications in real fields. It started with identifying the “reliability” of each and every node in the network and subsequently creating a “reliability table”. With the help of the “reliability table”, algorithm was developed for finding ‘Black Hole’ nodes in an ad-hoc network, which can break down the communication in the network. He then switched to the use of cryptography in any network in general. Starting from the basic of cryptography like cypher text, symmetric key, and asymmetric key, he moved to public key, private key cryptography advance ideas used by modern online systems to secure their communication channel. He clarified various important jargons like Digital Signature, Message Digest etc., and at the very end he showed how symmetric and asymmetric key both can be applied together to make the transferrable data secure, authentic and light weight so that we can make better transfer over the internet.

The session was very productive for the students as they were learning a lot within this two and half hour session. The prof. Chatterjee allowed the students to ask as much questions as they want as he conducted the session in very open and friendly manner. The session was concluded by the campus director Dr. Bose offering Mr. Chatterjee a memento out of gratitude for such a wonderful knowledge sharing session.
