Annotation:

In this fast-paced era of technology, when all the information moves into the technology, it also affects money. Electronic money is already widely used and is gaining popularity in many countries. But where there is technology, security should be taken into account. Cryptography, a branch of mathematics is concerned with information security.

Cryptography covers four main tasks: data confidentiality, data integrity, authentication of data source and user authorization.

The dissertation is an integrative work of cryptographic protocols that are reasonably secure and effectively implemented on mobile devices. Based on these concepts, scientific novelty was achieved. The electronic money system developed in the dissertation does not increase the amount of data during transfers when the anonymity between the Bank and the Purchaser is removed. Such a system also retains its main properties: offline payments, money transferability, the Purchaser’s anonymity from the Vendor, and prevention of double spending, traceability and security.

The thesis demonstrates that the new electronic money system is secure, trustworthy and efficient. In order to prove it, world recognized methods are used.
