Crosshill Ltd

Our mission at Crosshill is to make sure, that you as a customer are using, developing and delivering fully secured embedded solutions, without the risk of backdoors, system manipulations or counterfeit parts, that would cause unpredictable financial and operational damage in the case of security breach. Therefore, we want to keep you one step ahead in this everlasting security race, and our passion is helping you to achieve this. Crosshill provides security and attack testing services to evaluate overall security level of embedded systems and devices. State-of-the-art passive and active testing methods are used, such as side-channel attack testing, fault injections, cryptanalysis and electromagnetic spectrum analysis. The customer gets valuable information about the critical security vulnerabilities in hardware, low-level software and application software layers, that would endanger the entire security in the embedded system. Based on this information, we will give guidelines how to improve security, and optionally we can implement them directly for the customer. Crosshill engineers and manufactures advanced high security embedded systems, to create secure proof and attack resistant solutions for the customers. A customer project starts typically with the pre-study or concepting, where the system requirements, features and security levels are defined. The development work continues with embedded hardware and software design, integrating anti-tamper protection mechanisms, countermeasures and cryptographic algorithms deeply into the system. The developed solution is validated with several testing methods to fulfill security, functional, EMC and environmental requirements, before the manufacturing and mass production phase. Security aspects are integrated also into the production, where component sourcing, assembly and software integration are the most critical parts. Now the embedded solution is ready for the secure delivery and operational use.
