ISA100 Wireless provides robust, multi-tiered, policy-based security to ensure the safety of system operations. Communications are protected using a time-enhanced application of the NIST standard 128-bit Advanced Encryption Standard (AES) block cipher. Only devices that have legitimate and unique secret join keys are admitted to the network. Multiple-tiered AES-128 keys are derived from join keys and updated periodically. This secure key derivation method is the basis for a trusted relationship that makes the ISA100 Wireless network secure throughout the entire system life cycle.

Completely Wireless

ISA100 Wireless delivers the first completely wireless security solution on the market. When building, installing, or maintaining a wireless device, a wired provisioning interface adds time, cost, and risk. ISA100 Wireless uses infrared ports or over-the-air communications to make provisioning convenient and safe.


The security industry is evolving rapidly, and ISA100 Wireless’ security features are designed with change in mind. Scalable encryption in two security layers ensures that ISA100 Wireless products and systems will continue to meet users’ and regulatory agencies’ future security needs.


AES-128 security is the industry standard. We’ve made it better. By adding an additional layer of security based on time signature, ISA100 Wireless systems are protected against replay attacks.


Anyone can claim their system is secure, but the open, consensus-based design and review process ensures ISA100 Wireless delivers confidence. Its security is based on the well-established NIST standard 128-bit AES block cipher and has been validated by a broad range of security experts from industry, government, and academia.
