DNA cryptography

DNA computing may not be fast but it is massively parallel. With the right kind of setup, it has the potential to solve huge mathematical problems. It's hardly surprising then, that DNA computing represents a serious threat to various powerful encryption schemes such as the Data Encryption Standard (DES).

Quantum cryptography

Quantum cryptography may be perhaps five years ahead. Quantum computing may possibly be 15 years away. Progress in building quantum computers tends to develop in steps as researchers find new methods, so it is slow, but the theory is solid.
