       WISeKey's Semiconductor products with embedded security are immune to hardware bugs such as Meltdown and Spectre

ZUG, Switzerland - January 8, 2018 -WISeKey International Holding Ltd ("WISeKey", SIX: WIHN), a leading cybersecurity and IoT company, today  announced that its  products and software solutions are immune to hardware bugs such as  Meltdown and Spectre.  As per the recent news, practically every computer device, server, laptop, tablet and smartphone in the market was affected by two major flaws in the design of the device's Central Processing Unit (CPU), allowing hackers to steal data.

"Not only are WISeKey's products immune to attacks by Meltdown and Spectre and similar hardware bugs," explains Carlos Moreira, Chief Executive Officer and founder of WISeKey, "but our security solutions are designed precisely to make these kinds of attacks ineffective.  We believe that the phenomenon of the two side-channel attacks wouldn't exist if our embedded security solutions were implemented from the start in the CPU system of these devices." 

Following the Meltdown and Spectre attacks, to minimize the effect of these incursions, operating system developers are offering emergency patches for download. As per the United States Computer Emergency Readiness Team (US-CERT), due to the fact that the vulnerability exists in the CPU architecture rather than in the software, emergency patches offered by operating system developers may not fully address these vulnerabilities. Moreover, CPU performance may be diminished by up to 30 percent after a patch is installed. (https://www.us-cert.gov/ncas/alerts/TA18-004A).

The Meltdown and Spectre side-channel attacks are geared towards a specific microprocessor architecture that can be found on almost all personal computer devices, servers, laptops, tablets and smartphones. In search of cost and speed optimization, since the 1980s, microprocessor designers took the approach of implementing security through the use of "layers of privilege" within the architecture of a computer system.   This approach is designed to provide access to the data relative to the privilege of each user. Thus, an operating system kernel has very high privileges and access to secret data such as passwords and private keys, while user applications have lower privileges and no access to such sensitive information.

The two side-channel attacks consist of running malicious code which will, by making use of the three technologies (Branch Prediction, Speculative Execution and Memory Caching) implemented by these processors, interrogate the memory channel of another processor belonging to another user with different layer of privilege, thus granting unauthorized access to very sensitive information, including passwords and private keys stored deep inside the operating system. Once this information is in the hands of a third party, or even supposed to be disclosed to a third party, the entire system of trust built on it, will collapse. 

As Bernard Vian, Managing Director of WISeKey explains, "The secure chips designed by WISeKey, are based on a different architecture and approach. First of all, they are dedicated to providing secure storage and usage of sensitive assets. There is only one application running on these chips, dedicated to secure storage, cryptographic calculations and digital signatures, using the secret key material stored deep down within the protected memory of the chips.  The chips are designed with unique capabilities not to allow other software to run on them. Next to this functional approach of a dedicated container for a dedicated use, the chips are equipped with various hardware sensors and protection mechanisms making them resistant to hardware attacks. Would these kind of chips have been used for sensitive data storage on the now affected devices, the attacks would have never been possible.

"Now we are talking about an attack that is affecting several million devices. Imagine the Internet of Things (IoT) where we have tens of billions of devices. Do we want to wake up one morning to find our world crumbled down because of a massive breach in all these devices? Meldown and Spectre attacks demonstrate that these devices are vulnerable and if not protected, it is just a matter of time for these devices to become useless objects."

For more than twenty years, WISeKey has been providing a range of Common Criteria certified tamper resistant microprocessors that can be implemented on IoT devices to store and use the secret assets, and to uniquely identify, authenticate and protect devices in the field. These assets can be managed through a Webtrustcertified Public Key Infrastructure on premises or as an operated service.

"Regardless, these kind of attacks, have provided all of us with valuable insights and have strengthen our approach towards security, which is the only effective way to protect IoT assets and value in a durable manner," concluded Carlos Moreira.
