eToken Application for Generating the Digital Signature Using the USB Interface

Abstract

This paper highlights some ways in which people can book, in a very simple way, a promotional package of e-commerce in tourist services, without the need for face-to-face communication. The entire transaction is executed online, but also in a secure way, ensuring the real identity of both the buyer and the seller. Users will benefit from various offers with a good value for money. Firstly, they will be able to follow the booking steps in a simple way, ideal for inexperienced users, with instructions and warning messages. Secondly, it is no secret that today's people are busy, the lack of time is more and more accentuated, and the online environment has gained ground in their lives. Along with online transactions, human or system errors have appeared, users being often put in unpleasant situations. One solution to this problem is the token device - a device with a special structure that incorporates cryptographic algorithms (symmetric and asymmetric) that allow the safe performance of cryptographic operations. In the application presented in this paper, both users and sellers digitally sign holiday booking documents, thus managing to provide beneficiaries with a strong reason to confirm that the digital document is created by the person who signed it, and the content of the digital document has not been modified since its date of issue.
