Introduction to Cryptography
20th September 2017
ISTE Student Chapter, Dronacharya College of Engineering, Gurgaon organized one- day workshop on the topic “Introduction to Cryptography”. The lecture was conducted by Prof (Dr.) Rajendra Kumar Sharma, Faculty of Mathematics, IIT, Delhi. First year student (CSE) attended the workshop.
The main objective of the topic was to bring awareness and enlightenment among the first year student about application of Mathematics in Engineering.
Dr. Sharma began by giving an insight and edification on the subject to bring cryptography through pedagogy. Students were annunciated along with activities on developing schemes and formulas to enhance the privacy of communications through the use of codes or ciphers.
Dr. Sharma also delivered a descriptive information on cryptography, it is a science which uses the mathematics to encrypt and decrypt the information; it empowers to save the sensitive data. The feature of cryptography provides security and makes only the aimed recipient to read the data. So, it is also called as a science of defending or protecting data and the cryptanalyst is called as attackers.
He stressed on modern cryptographic systems, which rely on functions associated with advanced mathematics, including a specialized branch of mathematics termed number theory that explores the properties of numbers and the relationships between numbers. He has also shown some interesting results in number theory. Further he discussed cryptographic process in which encryption and decryption is done by various many cryptographic functions, Hash functions, and algorithm RSA. RSA algorithm published by Ronald Rivest, Adi Shamir, and Leonard Adleman designed to become a major advancement in cryptology. The algorithm underlying the system derives its security from the difficulty in factoring very large composite numbers and it became most commonly used encryption and authentication algorithm in the world. The RSA algorithm was used in the development of spreadsheets, Internet web browsers, data analysis, email and word processing programs. He also told cryptography plays a very important role in authentication, data confidentiality, data integrity and non-repudiation.
In the end, he concluded his lecture by giving some exercise on code terms and students were able to derive the message corresponding to given codes. The workshop was ended with a vote of thanks given by Mrs. Sangmitra V. Arora, HOD of Applied Sciences and Humanities Department.
The session was very interactive and students actively participated.
