“…Security is the main requirement for mobile payments because the information exchange among participants is money, and participants do not want to lose money. The number of cryptographic operations is very similar to related works [8,13,23,[30][31][32] which means that P2PM-pay is efficient in terms of processing time. …”

“…Moreover, in terms of performance the schemes should require low computational power, low storage capacity and low administrative cost. Although many proposals of mobile cash or electronic cash can be found in the literature, few of them [28][29][30][31][32][33] prevent the bank's database grows very fast. However, these schemes do not take into consideration the authentication process among participants.…”

In this paper, we propose P2PM-pay scheme which provides two key points. The first key point is related with the mobile cash. In P2PM-pay scheme, the mobile cash is controlled by the expiration date. The expiration date is embedded into the mobile cash by partial blind signature during the withdrawal date, and the bank does not hold information about the operation. Moreover, we have considered the effective date and deposit date for administrative purposes. The effective date is when customers use their mobile cash to pay for products, and the deposit date is when merchants receive the funds in their bank account. The other key point is related with the authentication process among participants. Although P2PM-pay uses WTLS protocol, we propose a wireless public key infrastructure with an efficient certificate path validation. Furthermore, the design of the proposed scheme achieves successfully the security requirements described in previous works. Consequently, P2PM-pay is secure against well-known attacks and efficient in terms of processing time.

In an electronic cash scheme, there are three participants, the bank, the spender and the merchant. First, a spender opens an account in a bank. Then, he withdraws electronic cash from his account and pays it to a merchant. After checking the electronic cash's validity, the merchant accepts it and deposits it to the bank. There are a number of requirements for an electronic cash scheme, such as, anonymity, unforgeability, unreusability, date attachability, divisibility, transferability and portability. In this paper, we show a recently proposed electronic cash scheme is suffering from some faults in anonymity, expiration date and merchant frauds. To improve the scheme, we propose a new untraceable off-line electronic cash scheme and give a security analysis for it. 432Copyright ⓒ 2016 SERSC requirements, such as, anonymity, unreusability and date attachability. However, Baseri, et al.,[14] showed that Eslami and Talebi"s scheme is subjected to some weaknesses in perceptibility of double spender, unforgeability and date attachability. Baseri, et al., also contributed an electronic cash scheme and claimed that their scheme is immune to the weaknesses of Eslami and Talebi"s scheme. But, as we show in this paper, Baseri, et al.,"s scheme is suffering from some faults in anonymity, expiration date and merchant frauds. To improve Baseri, et al.,"s scheme, we also propose a new untraceable off-line electronic cash scheme. The new scheme not only possesses the features, such as anonymity, unforgeability, unreusability, but also possesses the feature of avoiding merchant frauds.The remainder of this paper is organized as follows. Some basic concepts are introduced in Section 2. In Section 3, we review Baseri, et al.,"s scheme and show its weaknesses. In Section 4 we propose a new electronic cash scheme. Security analysis of our scheme is covered in Section 5. Performance comparisons are shown in Section 6. We finally conclude in Section 7.
