Abstract (en)
[origin: WO2004057547A1] A verification system (200) and a method to, at a wireless telecommunication and data communication network (100), make earnings possible for a card issuer (118). The verification system is based on open, standardized interfaces. When a digital signature has been created on a smart card (102) in a mobile unit (104), the digital signature is encrypted with/by a key which belongs to the card issuer before the signature leaves the smart card. The encrypted signature is transmitted/transferred to the signature receiver (112) in the same way as if it had not been encrypted by the card issuer's key. The signature receiver after that transmits the signature to the card issuer. The card issuer decrypts the signature, debits the signature receiver and transmits the decrypted signature to the signature receiver. After that, the signature receiver can check the digital signature.
