| Certicom Security for Sensor Networks Certicom Corp. has launched Certicom Security for Sensor Networks, a software module and hardware IP core, that secures low-power, wireless sensor networks. The products use elliptic- curve cryptography (ECC) to add a provable identity to sensor devices, which provides security and reliability from design and development through to the manufacturing, deployment and upgrade of a sensor network. Today's wireless sensor networks are generally small (fewer than 100 nodes) so symmetric cryptography with centralized control of security is sufficient. However, for sensor networks to reach their potential - to build large, self-healing networks that allow nodes to move as necessary - developers of microcontrollers and sensor networking stacks must move to public-key cryptography, which enables devices to interact and communicate securely. ECC provides more security per bit than other public-key cryptography schemes making it the only option that can meet the footprint and power limitations of a sensor network's constrained devices. Certicom Security For Sensor Networks includes: Certicom MCE (Microcontroller Edition), a software module that provides cryptographic primitives that interface with the networking stack through a common application programming interface; and Certicom ECC Core a hardware IP core that accelerates and offloads the processor-intensive public-key security operations. Features and benefits: * Provides provable identity: A stored public and private key pair provides a digitally provable identity and facilitates digital signatures and secure key exchange * Flexibility: Node mobility and automated network enrollment methods enable more flexible topologies and a wider variety of applications * Optimized performance: optimized software cryptography and hardware acceleration deliver strong security without impacting network performance * Simplifies network deployment: Provable identity authenticates a node automatically and enables mobility across multiple networks. write your comments about the article :: © 2006 Networking News :: home page |
