The Transparent Authenticated Secure Storage Integrated Circuit (TASSIC) from Tropic Square is a cryptographically and physically secured, non-volatile storage chip.
TASSIC is designed for the special purpose of handling digital secrets and serving as a fundamental building block for digital trust, in a minimalistic implementation. Its cryptographic key management and ability to derive a digital unique identity secures storage in embedded systems and trusted digital devices.
Serial interfaces and compatibility with the ISO 7816-3 protocol positions TASSIC as a drop-in replacement for serial flash devices and secure elements. It shortens time to market with transparent and auditable chip implementation. Open-source, production-grade software drivers and an FPGA-executable functional model of TASSIC are coming soon.
- TASSIC transformation of a low-entropy secret (PIN) to a high-entropy secret can be used in various cryptographic applications.
- TASSIC focuses on security at all stages of the chip lifecycle. From manufacturing, through deployment, runtime, and even when powered off.
