Future Forms of Cryptography

The current generation of technology reflects the evolution of past technologies and techniques. The classic view of cryptography sees the key as both the power and the limiting factor for implementing cryptography solutions. Security professionals have found that, in practice, it is exceedingly difficult to generate and secure good encryption keys. However, there is good news. Cryptography research is a rich and varied field, and there are many ongoing efforts to advance the state of the art. Although most implementations of cryptography are still based on keys, next-generation cryptography approaches generally focus on techniques that reduce the emphasis on generating keys. Several relatively recent directions ...
