Pragmatic Key Management for Data Encryption

Last Updated: Friday, October 19, 2012

Few terms strike as much dread in the hearts of security professionals as key management. Those two simple words evoke painful memories of massive PKI failures, with millions spent to send encrypted email to the person in the adjacent cube. Or perhaps they recall the head-splitting migraine you got when assigned to reconcile incompatible proprietary implementations of a single encryption standard. Or memories of half-baked product implementations that worked fine in isolation on a single system, but were effectively impossible to manage at scale. Where by scale I mean “more than one”.

Over the years key management has mostly been a difficult and complex process. This has been aggravated by the recent resurgence in data encryption – driven by regulatory compliance, cloud computing, mobility, and fundamental security needs.

Fortunately, today’s encryption is not the encryption of yesteryear. New techniques and tools remove much of the historical pain of key management while supporting new and innovative uses. We also see a change in how organizations approach key management – toward practical and lightweight solutions.

This paper explores the latest approaches for pragmatic key management. We will start with the fundamentals of crypto systems rather than encryption algorithms, what they mean for enterprise deployment, and how to select a strategy that suits your particular project requirements.
