Part 1 – Increasing Efficiency & Resilience
This two-part article discusses how cryptography is employed within organizations today and examines some of the challenges it raises, both for large, established enterprises and for start-ups within emerging markets such as FinTech, Internet of Things (IoT) and blockchain.
This article discusses the various issues around key management and presents Cryptomathic’s approach to central key and crypto management that has been adopted by major banks.
With the ever increasing number of online services and electronic transactions, business owners are becoming ever more dependent on the use cryptography to prevent sensitive information from cyber attackers.
A Key Management System (KMS) must be designed in a manner that supports the goals of each organization using the KMS. The aim of a security policy is to provide a secure working environment for the organization by establishing required security measures, protocols and controls.
Cryptographic keys are used to secure data-at-rest and data-in-transit. Trying to keep them protected yet always available for use is one of the most difficult problems in practical cryptography. Improper key management can lead to key leakage, where an attacker obtains the key and recovers the sensitive messages from the encrypted data.
This article discusses the key management problems and Cryptomathic's approach to solving the challenges faced by large organizations that use cryptography for variety of applications.
Recent revelations in the press have caused industry experts to question just how much trust can be placed in existing cryptographic standards or even in certain methods of generating key material. Companies must be prepared to respond quickly and effectively to such changes in the security landscape, else they risk reputational damage and significant costs in the event of a breach.
To understand why this preparation is challenging, we should consider how cryptography is commonly deployed within a business.

To date the deployment of encryption services and the techniques used to achieve interoperability and technical standards have always lagged behind what businesses have actually needed, or for that matter, what regulators or certain schemes are enforcing.

This second decade since the Millennium is seeing a major uplift in the use of cryptography in existing and new business systems. This uplift is likely to be disproportionately greater than the actual increase in business transaction volumes.

There has been a substantial increase in the use of cryptographic techniques and Hardware Security Modules (HSM's) in larger commercial enterprises, and banks in particular, since the upsurge of online services in the late 1990's. Invariably this has been undertaken on a project basis, with each project having its own goals and initial budget.
