Gothenburg, Sweden (April 3, 2025) – Frontgrade Gaisler, a leading provider of radiation-hardened microprocessors for space missions, and wolfSSL, a renowned provider of embedded security solutions, are pleased to announce a new collaboration that addresses the growing need for robust cybersecurity features in space applications. This joint effort will combine Frontgrade Gaisler’s radiation-hardened electronics with wolfSSL’s security software libraries.
At the highest Technology Readiness Level of 9 (TRL-9), the Frontgrade Gaisler’s GR740quad-core microprocessor is trusted across multiple space mission profiles. The microprocessor’s software ecosystem is now further enhanced by porting wolfSSL’s wolfCrypt robust cryptography library. This integration offers customers a combination of rad-hard hardware and resilient cybersecurity software. WolfSSL’s wolfCrypt library equips users with a lightweight, high-performance cryptographic solution that ensures secure communications, data integrity, and protection against cyber threats in space-based applications. Forward-thinking users will benefit from the support for post quantum cryptography and CNSA 2.0.
“We understand the growing need for secure solutions in space technology,” said Sandi Habinc, General Manager at Frontgrade Gaisler. “By collaborating with wolfSSL, we are now enabling our customers with the reliable software needed to address their cybersecurity requirements.”
“Security is paramount in space applications, where reliability and resilience are critical. By integrating wolfCrypt with Gaisler’s GR740 processor, we’re providing a proven, lightweight, and high-performance security solution that meets the unique challenges of space environments,” said Larry Stefonic, Chief Executive Officer of wolfSSL. “We look forward to expanding our collaboration to bring even stronger cryptographic capabilities to future space missions.”
Looking ahead, Frontgrade Gaisler and wolfSSL are excited to expand their collaboration. Planned future developments include a port of wolfHSM software to the Hardware Security Module (HSM) in Gaisler’s upcoming GR765 octa-core rad-hard microprocessor. The combination would create an isolated platform for key storage, signature verification, and crypto acceleration that would be easily accessible through wolfCrypt.
