W artykule przedstawiono propozycje protokołu płatności w sieciach bezprzewodowych. Protokól zakłada dwie techniki realizacji transakcj i: w trybie on-line z udziałem zaufanej strony - dla tzw. makropłatności oraz w trybie off-line przy użyciu elektronicznego pieniądza, głównie dla transakcji o małym nominale - tzw. mikropłatności. Omówiono scenariusze różnych zdarzeń i transakcji w protokole. Zwrócono uwagę na aspekty bezpieczeństwa płatności uwzględniając techniki kryptografii asymetrycznej i infrastruktury kluczy publicznych. Dla oceny protokołu wykonano testy, w których uwzględniono kryteria charakterystyczne dla środowiska bezprzewodowego.

The article proposes a payment protocol in wireless network. The protocol assumes two techniques of transaction realisation with the division between on-line payments with a trust third party - for macropayments and transactions in the off-line mode with the use of electronic money, mainly for transactions of small denomination - the so-called micropayments. Various events and transactions in the protocol as well as the scope of information and annoucements required for them are presented. An asymmetric cryptography and a public key infrastructure are exploited to provide payment security. In order to define quality of the protocol under regard of the characteristic criteria for a wireless environment were carried out its examinations. Usefulness of the payment protocol was evaluated using various measures. The best system has to demon-strate friendly properties for its users. An introduced model fulfils these expectations by delivering possibility of transactions of large amounts as well as of micropayments. Thanks to the use of digital cash transfer a user gets confidentiality. This makes the procedure simpler and a user does not absorb processor on a card through complicated and time-consuming cryptographic procedures. One of the objectives in designing the protocol was to minimize quantity of data exchanged to meet requirements of wireless networks. Due to this a user can execute payment operations in a fast and cheap way. The desired properties of encryption and decryption are obtained by applying the elliptic curves cryptography (ECC). It was confirmed by researches and tests and why it one was used in our protocol.
