101st Remembrance Day of Srinivasa Ramanujan
We are happy to share the abstract of the talk to be delivered by Dr. J. Baskar Babujee in the occasion of 101st Remembrance Day of Srinivasa Ramanujan conducted by Pie Mathematics Association on 1st May, 2021.
Encryption today has grown into such specialized field that involve mathematical, non-linear cryptosystem that even a relatively powerful computers take months or even years to break the cipher text. Now a day’s most of the fields say clients' credit card numbers, social security numbers, tax file numbers etc needs to be kept secret when they send it electronically. There are various methods used to encrypt the numbers. It has been recognized that encryption and decryption mostly emerges from mathematical disciplines. In this talk, we give a new combinatorial technique to encrypt and decrypt numbers through labeled graphs using the residue modulo class Z3.
