SubGHz/SIGFOX SECURE CHIP UFDFP Description


STSAFE-A1SX


The STSAFE-A1SX is a secure element that comes preloaded with Sigfox network keys, and provides secure services for data exchanges on the Sigfox’s low-power wide-area network (LPWAN). It constitutes a plug-and-play solution that allows Sigfox Ready™ IoT (Internet of things) devices to connect to the Sigfox network while ensuring data integrity and confidentiality. The STSAFE-A1SX is a highly secure, tamper-resistant solution that relies on a certified, secure EAL5+ Common Criteria chip, on top of which runs a dedicated secure operating system.
