and storage system with
HW root of trust


MicroCloud X4 – IoT Plug and Play Secure Storage and Computing

Bluechip Systems has developed the MicroCloud X4 in MicroSD form factor to deliver plug-and-play secure storage and computing at the edge. MicroCloud X4 is powered by a CoolEngine™-based SoC. CoolEngine’s low-power, high-performance processor IP enables MicroCloud X4 to deliver best-in-class programmable processing. MicroCloud X4 has a broad range of applications, able to be used in secure storage, communication, operating systems, and processing environments for use in enterprise, government, and consumer solutions.

MicroCloud X4 is the only commercially available platform providing a unique solution for cyber security challenges

  • End-point hardware-isolated computation and storage with HW Root of Trust
  • Suitable to run heavy duty vision and sensor processing, AI, and learning algorithms on the edge
  • Plug-n-play operation via industry-standard interfaces (SD, microSD, USB)
  • Flexible programmability agnostic to host hardware architecture, OS and networking
  • Smallest possible footprint and ultra-low power consumption
  • FIPS 140-2 Level 2 certified: Overall Level: 2, Physical Security: Level 3 and EMI/EMC: Level 3
  • NIAP Common Criteria Full Drive Encryption (in evaluation)
  • Industry and government-grade environmental specifications
  • Complete suite of HW and SW developing kits

MicroCloud creates a plug-and-play security envelope for stand-alone or networked devices, making them
impregnable from most harmful types of cyber attacks. MicroCloud can protect:

  • Sensitive user data in phones, tablets, flash drives and security cards
  • Residential and Enterprise Gateways
  • Smart meters of power grids
  • Sensors of oil/water/gas pipelines
  • Sensors and controls of autonomous and connected vehicles and drones
  • ATMs and Point of Sale terminals

Example use cases for MicroCloud X4 are:

  • Secure storage and processing on Android host
    • Keystore, data storage, encryption in hardened or BYOD phones on public or private networks
  • Dual Persona on Android host
    • Secure OS image boot on BYOD/hardened phones/tablets
  • Secure storage on non-Android host
    • Self-encrypting flash drive, security smart card, data container in UAV or camera
  • Secure processing on non-Android host
    • Oil/gas/water grid sensors, image processing in security TV/camera, body sensors, autonomous
      cars lidar/radar
  • Secure storage and processing on non-Android host
    • IoT End-point security: smart meters, gateways, POS, medical equipment

FIPS Certification

“National Institute of Standards and Technology (NIST) established the Cryptographic Module Validation Program
(CMVP) that validates cryptographic modules to Federal Information Processing Standards (FIPS). Modules
validated as conforming to FIPS 140-1 and FIPS 140-2 are accepted by the Federal
Agencies for the protection of sensitive information.” MicroCloud X4 is certified as FIPS
140-2 Level 2 certified: Overall Level: 2, Physical Security: Level 3, and EMI/EMC:
Level 3. This certification covers a MicroCloud-based product which performs Data at
Rest encryption. Based on progress with the above certifications and on compliance
with DoD Instruction 8500.01 and 8510.01, a customer in the United States
Department of Defense has issued an ATO for a Secure Communication Suite, which
is based on mobile phones equipped with MicroCloud, running secure comms
applications and operating on a proprietary network.

NIAP Certification

“The National Information Assurance Partnership (NIAP) oversees a Common Criteria Evaluation and Validation
Scheme (CCEVS or Scheme) to help manufacturers of COTS products gain acceptance in the global marketplace.
Successful evaluations benefit industry product developers/vendors and government
procurers by validating that the products meet security requirements for U.S. national
security system procurement. Because NIAP is a member of the international 28-nation
Common Criteria Recognition Arrangement (CCRA), NIAP-validated products are also
available to procurers in the CCRA member nations. All products evaluated within the
Scheme must demonstrate exact compliance to the applicable technology protection
profile”. MicroCloud X4 is listed as Product in Evaluation . This certification will cover a
MicroCloud-based product that performs self-encryption protection of Data at Rest in a
mobile phone.
