One-time pad
In cryptography, the one-time pad (OTP) is an encryption technique that cannot be cracked, but requires the use of a single-use pre-shared key that is not smaller than the message being sent. In this
Information-theoretic security
A cryptosystem is considered to have information-theoretic security (also called unconditional security) if the system is secure against adversaries with unlimited computing resources and time. In con
Shamir's Secret Sharing
Shamir's Secret Sharing (SSS) is an efficient secret sharing algorithm for distributing private information (the "secret") in such a way that no individual holds intelligible information about the sec
