BENEFITS OF A TID ROLLOVER AND STS EDITION 2
The STS Edition 1 Specifications have been used successfully for more than 25 years, and with the recent launch of STS Edition 2 specifications, significant benefits for the industry can be realised, these being:
Enhanced algorithms for vending key creation and protection - the new system will use up to 192 bit encryption and state-of-the -art algorithms approved by NIST for use at least up to 2045.
Key expiration - the new system will allow for a vending key to be expired after a certain time (chosen by the SGC owner). This ensures that even if a vending key has been compromised, the key will expire after a certain time. This will significantly reduce the risks associated with the theft of standalone vending systems or security modules.
The longevity of the STS system is guaranteed.
All STS prepayment meters that have been using tokens purchased from un-authorised vendors will reject these tokens after the TID rollover key changes have been performed.
