Solution

Description

AgilePQ has developed an innovative method to protect IoT devices. The Secure Last IoT Mile (SLiM) Cipher Suite secures data in transit by using a key server that is optimized for a very small encryption algorithm installed on the IoT devices. In fact, AgilePQ’s algorithm is >1,000 times smaller than the IPSec standard developed more than 20 years ago. By reducing the algorithm size, the company was able to increase its key size to 256!, making the total key space 400+ times larger than the IPSec total key space. The SLiM Cipher Suite is protected by numerous patents.

NIST COMPLIANT

NIST’s Cybersecurity for the Internet of Things (IoT) program supports the development and application of standards, guidelines, and related tools to improve the cybersecurity of connected devices and the environments in which they are deployed.

POST-QUANTUM PROTECTION

Quantum computers will soon break the IPSec encryption methods developed more than 20 years ago. This puts encrypted data at risk. AgilePQ protects against current and future attacks by increasing encryption key space to 256! (400+ orders of magnitude more secure than AES 256).

LIGHTWEIGHT SECURITY

With device visibility, AgilePQ enables you to know what’s on your network, detect threats on IoT devices, manage the devices, and gain insights to make informed decisions about your IoT device security, all while intercepting and stopping threats to all data in transit.

IoT CHALLENGES

The Internet Engineering Task Force (IETF) classifies connected, small IoT devices into three categories according to processing ability, memory size, and power consumption. While IPSec security works on large devices not classified by IETF (smartphones to servers), it does not work on IoT (Class 0 – 2) devices because the code size and compute power necessary simply don’t fit given limited CPU and RAM resources.
