Tandem Computers Inc’s San Jose-based Atalla Corp says its new A- 5000 High Performance Security Module is now available for channel-attachment to Tandem NonStop VLX, TXP, EXT and NonStop II machines, claiming that it offers more than six times the performance of its previous generation A-1 Security Module: the new one is claimed to process over 60 transactions per second to providing a secure, cost-effective system for high-volume transactions, protecting the data against unauthorised access or alteration as it passes through the network; Personal Identification Numbers are translated, verified and encrypted in hardware so that they remain private to the owner – and if any attempt is made to open the Security Module, all cryptographic keys are automatically erased; available in April, it is $47,500, and Atalla claims that complete fault tolerance can be achieved by installing two of the new Modules.
