Sepior TSM

The Sepior Threshold Security Module (TSM) is a system for using and managing cryptographic keys. The Sepior TSM is based on threshold cryptography which is a way to do key management using the state-of-the-art cryptographic technique called Multiparty Computation.

A TSM is constituted by a number of different artefacts:

• A cluster of n so-called MPC nodes
• A set of cryptographic MPC protocols implementing cryptographic primitives as threshold cryptography
• An optional administration tool
• An optional audit-log service
