Σύγχρονα Συστήματα Κρυπτογράφησης με Εφαρμογή στα Κρυπτονομίσματα
Translated title:
Modern cryptographic systems with cryptocurrency applications
Summary:
The invention of bitcoin and blockchain would not have been possible without the rapid
development of cryptography in the late 20th century. The use of cryptographic methods
such as digital signature, hash functions, and Merkle trees ensure that every blockchain user is assured that the information stored and transmitted through the blockchain is verified and secure.
In this work, the cryptographic methods used in blockchain are analyzed in detail and the
function of the basic cryptocurrency (bitcoin) is presented. Additionally, the main cryptocurrencies and their different approaches to the digital currency ecosystem are mentioned as well as the different uses of blockchain in various sectors of the economy and commerce.
Finally we have chosen to introduce some new types of digital signatures, called aggregated signatures and we also consider their possible implementation in blockchain .
