Abstract:
The documented history of cryptography dates back to a few thousands of years, when humankind went innovative to infuse the element of secrecy in communication. With the advent of the era of digital communication, mathematical algorithms dominated the arena of data encryption. As the computation technology improved in processing capabilities to break the mathematical algorithm based encryption, there emerged the disruptive technology of quantum cryptography as an antidote. To add a new dimension to it, the space technology joined hands with quantum mechanics to build the edifice of space based quantum communication, which now underpins the future of satellite data security. This lecture will address the fundamentals of the subject in a way suitable for audience from all disciplines of science and technology.
