	SwRI engineers use state-of-the-art test equipment, software tools, and laboratory facilities to evaluate the capabilities, benefits, performance, and costs associated with alternative embedded system implementation.

The evolution of computing and information technology is resulting in migration beyond centralized enterprise and desktop systems and out to increasingly sophisticated embedded devices in the field. This creates significant opportunities for equipment manufacturers to have real-time insight into customer operations and to offer additional value-added services and technologies. Many opportunities exist for better use of limited communications channels by leveraging the computation power now resident in existing and emerging network-enabled devices, weaponry, sensors, and situational awareness systems.

However, as information is pushed to the edge of the extended network,

opportunities also exist for:

• Devices to be compromised

• Intellectual property to be stolen

• Information to be exploited and/or altered

Therefore, implementing security in embedded systems and providing secure communications paths back into the enterprise are paramount.

Southwest Research Institute (SwRI) engineers have the multidisciplinary experience to bring together the disparate worlds of security and embedded systems. The SwRI Communications and Embedded Systems Department staff has expertise in embedded hardware and software development, radio and network communications, and cyber security.

	Prototyping and implementation of embedded security features involve the integration of real-time operating systems, protocol stacks, and cryptographic algorithms within resource-limited hardware platforms.

Sample Technologies

SwRI engineers have expertise in numerous technologies relevant to embedded systems security, such as:

• Mutual authentication

• Embedded public key infrastructure (PKI)

• Information integrity

• Nonrepudiation of information changes

• Role-based access control

• Digital rights management
