Information-Theoretic Security: Creating 21st Century Cryptography Standards

Most modern cryptographic schemes rely on complexity for security - they can be cracked, but that would take a prohibitively long time, even with enormous computational resources. Information-theoretic security, in which even an adversary with unbounded computational power could extract no useful information from an encrypted message, is far too complicated to be practical. With the current White House administration engaged in an unprecedented level of domestic spying, there is a great deal of interest in privacy even the government can't crack. read more
