Sensus using IBM technology for smart grid security

Raleigh, N.C., July 6, 2011 — Sensus is incorporating encryption and key management technologies from IBM into its FlexNet advanced metering infrastructure (AMI) system in an effort to advance data security as a component of the smart grid. The initiative will further enhance the existing security capabilities of the Sensus network infrastructure.

Sensus will integrate IBM's asymmetric encryption and enhanced key management technologies into its FlexNet communications system for electric, gas and water utility smart endpoints, including meters and distribution automation devices.

Specifically, Sensus will use the IBM Tivoli Key Lifecycle Manager software to centralize and automate the encryption key management process for all network deployments. Further, the technology integration will include NSA Suite B standards compliant cryptographic logic from IBM in all newer generation devices.

IBM will implement an asymmetric key based solution using elliptic curve cryptography. In addition to the strong confidentiality and integrity of the existing encryption protocol, Sensus FlexNet customers will get the added benefit of digital signatures and non-repudiation.

Sensus expects to have the new IBM encryption and key management functionality available to customers by early 2012.
