DEVELOPMENT AND SOFTWARE IMPLEMENTATION OF THE PROTECTION METHOD FOR THE PERSONAL KEY OF THE BITKOIN - WALLET FROM DATA LEAKAGE
The article discusses one of the most notorious cryptocurrencies at the moment, namely Bitcoin. Bitcoin is the digital currency of our generation, which is also called cryptocurrency. This currency is not used by the central bank. Bitcoins can be used as a payment for goods and services to sellers. During the review, it was found out what Bitcoin is, how to start using Bitcoin and how to mine it. In consequence of the consideration of these issues, the crypto-resistance of this cryptocurrency was analyzed and the possibility of improving protection was revealed. Based on the research data, the authors proposed a software implementation of a method to protect against the leakage of a personal key from a bitcoin wallet using the RSA algorithm. By encrypting the password using the RSA algorithm, we get a more secure wallet, that is, our wallet uses not only the standard security algorithms of our wallet, but also a secure password to which the attacker cannot reach. Through testing, it was determined that the encryption of our password, which is encrypted using the RSA algorithm, increases by about 30 percent.
