Funded by the UK government's Industrial Strategy Challenge Fund (ISCF) Digital Security by Design (DSbD) programme, the project aims to update the security foundations of the digital computing infrastructure that underpins the entire global economy. Research by Microsoft has shown that around 70 percent of the vulnerabilities addressed through a security update each year continue to be memory safety issues. * UK government funds ARM to develop security IP The main anticipated output of DSbD is a technology platform prototype, designed and produced by ARM, the Morello evaluation board, which shipped to researchers this week. This uses an architecture called CHERI (Capability Hardware Enhanced RISC Instructions) developed with researchers at the University of Cambridge (CHERI) architecture that replaces software pointers in the chip. ARM has developed a prototype architecture based on the Cortex-A core that adapts the hardware concepts of CHERI. The hardware capability technology that is used in CHERI and in the Arm prototype architecture combines references to memory locations. These act as pointers, with limits on how the references can be used. These limits relate to the address ranges and functionality that the references can be used to access. This combined information, which is called a capability, is constructed so that it cannot be forged by software. Replacing pointers with capabilities in a program vastly improves memory safety, which is a key step for security. The benefit of hardware capability technology goes beyond memory safety. This is because the capabilities can be used as a building block for more fine-grained compartmentalization of software. Software that is constructed with fine-grained compartmentalization could result Security boost for RF modules Security boost for RF modules Business News | Oct 18,2021 Secure router safeguards industrial applications Secure router safeguards industrial applications New Products | Oct 18,2021 PragmatIC raises $80m for second plastic chip fab PragmatIC raises $80m for second plastic chip fab Business News | Oct 18,2021 Europe invests EUR227m directly in tech startups Europe invests EUR227m directly in tech startups Business News | Oct 18,2021 NXP, Qualcomm team on eSIMs for wearables NXP, Qualcomm team on eSIMs for wearables Business News | Oct 18,2021 Synopsys, Dassault Systemes team for lighting digital twin Synopsys, Dassault Systemes team for lighting digital twin Business News | Oct 18,2021 Sponsored Content Video / Webinar Channel [image_600x] [ifx_web-ba] [eenews-pow] [infineon-g] [1] Most recent articles 1.
