Cryptopista is an HSM ( Hardware Security Module ) incorporating the specific cryptographic functions and digital signature for the control of subscribers to Toll Highways.

Designed to guarantee the norm of inter-operability of the Means Of Payment (TAG’s), the system allows:

• Generation of keys for the recording of multiple TAG’s
  
  
• Checking of the authenticity of the TAG outside the toll station ( PORTICO ).
  
  
• Digital signature of the data of interchange between the Highway Concessionaries for the later clearing, or Chamber of compensation of payments
  
  
• Storing and safe custody of the master keys through anti-intrusion mechanisms.
