TSIM — karta SIM dla TETRA

A homemade radio identity card

A homemade smart card that serves as a TETRA radio's identity.

What it does

  • Replaces the original card in any terminal
  • Takes over the radio's network authentication
  • Manages the encryption keys

Every TETRA radio carries an identity module inside — the equivalent of a SIM card that tells the network who the terminal is and performs authentication. TSIM is a homebrew, open implementation of that module on a programmable smart card.

What it does

  • Full authentication of a terminal on a TETRA network
  • Key management and over-the-air rekeying
  • Stores the terminal identity like a factory module
  • Card personalisation with your own data
