EtherTrust

EtherTrust

Traditionally, a Secure Element (like a SIM card or a chip in a credit card) is a passive, isolated micro-controller accessible only via local physical interfaces like ISO7816, SPI, or I2C. EtherTrust’s groundbreaking vision is to make these highly secure environments natively compatible with standard internet architecture.

pNHSM

Personal Network HSM (pNHSM)

The EtherTrust Personal Network HSM (pNHSM) is an innovative hardware security architecture based on a grid of physically isolated Secure Elements. Each Secure Element operates as an independent TLS 1.3 Pre-Shared Key (PSK) server, uniquely identified by its Server Name Indication (SNI). A TLS Front Server provides TCP/IP connectivity and SNI-based routing to individual Secure Elements. Each element integrates its own Key Management System (KMS) and secure shell interface, enabling independent cryptographic operations and secure key management within a dedicated hardware security partition.

LeMonolith

LeMONOLITH is a compact, single-Secure-Element implementation of the EtherTrust pNHSM architecture. It combines a System-on-Chip (SoC), acting as a TLS Front Server providing TCP/IP connectivity, with a dedicated Secure Element operating as a TLS 1.3 Pre-Shared Key (PSK) End Server. The Secure Element provides a physically isolated security environment integrating its own Key Management System (KMS) and secure shell interface. LeMONOLITH delivers hardware-protected cryptographic services and secure key management in a compact, standalone network-connected device.
