Shifted to Own Residence

...Ultimately the dream came to truth. And the wait is over.
It is nice to share with you that on 31st July last we have shifted to our newly purchased flat, E-03 at newly constructed Madhu Mamata Apartment at Uttarayan, J. P. Avenue, Sagarbhanga, Durgapur-713211. It is a splendid experience of living at the own residence. This is on the third floor with the scene of busy highway being available from the front side balcony. The 50-flat apartment is yet to be inaugurated formally, although around 15 families already have started residing. We all in our family are proud of being in this apartment. Your best of wishes is what we desire to have.

Publication in JSIR

I’m happy to share with you that my paper, Ensuring Information Security through 123-Bit Recursive Substitution of Bits through Prime-nonprime detection of sub-stream (RSBP) has earned a place in Journal of Scientific & Industrial Research (ISSN: 0022-4456) in vol. 68, July 2009, pp. 584-591.
The paper, comprising of a very small but significant part of my own doctoral work in the area of cryptology, is co-authored by J. K. Mandal, currently associated with Kalyani University as Professor of Department of Computer Science & Engineering and Dean of Engineering, Technology and Management, under whose supervision I did my doctoral work during 2000 – 2004. The initial version of the paper was communicated in June 2007. After a constant interactive peer review process, finally it was accepted for publication on 27 March 2009.
This paper presents a 123-bit private-key based block-cipher, which is capable of encrypting data files of up to 11 MB. It is formulated on the basis of base-10 value corresponding to a block of bits, which is to be checked if is prime or not. It results in an alteration of size for file being encrypted. Its executable performance is analyzed on the basis of execution time, graphical layout of frequency distribution of characters, and Chi square values for varying degrees of freedom. The proposed cipher, termed as RSBP, is found to be highly compatible with existing cryptosystems.

Jishu in St. Xavier's School
It’s a huge satisfaction for us that our only son Spandanil (Jishu) has succeeded in getting admission to the reputed St. Xavier’s School, Durgapur in class I. An admission test for around 100 candidates was held on 27-03-2009 and on 30-03-2009 the list of only a few selected candidates was disclosed. His admission process is also over. Now, he is counting days for going to his new school. All Jishu needs from you is your blessings and best of wishes to him for his bright future.
Membership of CRSI and IAENG
Also, I express my gratefulness to International Association of Engineers (IAENG) for providing me its membership (Membership No.: 101520). Under this responsibility, now I’m a Society Member of IAENG Society of Computer Science.

Submission of Thesis by my First Scholar

It gives me immense pleasure and satisfaction to share with you that on last Thursday, 19-03-2009, my first doctoral scholar of NIT-Durgapur, Pranam Paul, incidentally who is also my colleague in Dr. B. C. Roy Engineering College, has submitted his Ph. D. Thesis after the completion of his work in the field of Information Security and Cryptology.
He has around 15 publications till date in his area of work, out of which 2 are in a reputed Korean Journal and 1 is in AMSE, France.
What he requires at this stage is the best of wishes from all of you. I also personally wish him my best of wishes.

A New Journey
Research Publication in AMSE France

A small part of the entire research activities of my doctoral scholar, Pranam Paul has very recently been accepted for publication as a research paper, Encryption through Block Substitution through Sequential Position in Set of Distinct Blocks in AMSE, France. He is likely to submit his Ph D Dissertation to NIT-Durgapur in this ongoing month. Incidentally, this is my 4th publication in AMSE Journals, the first three being with Prof. J. K. Mandal, the supervisor of my doctoral research.
