Mosca’s Inequality And Its Effect On Quantum Cryptography

Cryptic writing is said to have come into existence as early as 1900 BC when the Egyptian scribes used hieroglyphics to communicate. The methods of cryptography might have changed over the years but the central idea hasn’t changed much; either eavesdropping or evading them. According to Gary C Kessler, there are five primary functions of cryptography: Privacy/confidentiality: Ensuring that no one can read the message except the intended receiver. Authentication: The process of proving one's identity. Integrity: Assuring the receiver that the received message has not been altered in any way from the original. Non-
