2 Public Key Encryption Using the Squaring Function First Attempt

, 2008
In the encryption we’ve been doing so far, the sender and the recipient needed to preagree on a key. This is traditionally called “symmetric ” or “secret-key ” encryption. The idea of public key encryption is that I can walk into a room, announce my key,
