| description | This study investigates methods for securely storing private keys of accounts in blockchain networks, in particular, symmetric (AES) and asymmetric (RSA) encryption methods. Secure storage of a private key is a critically important task, since compromise of the key can lead to loss of user assets and significant losses. The paper focuses on advanced approaches, such as key fragmentation, parallel encryption, and combined use of AES and RSA algorithms.
The advantages of the AES algorithm are considered, which provides high encryption speed and efficiency due to support for parallel computing. RSA, for its part, guarantees a high level of security due to the use of long keys (2048 or 4096 bits) and the ability to store private key fragments in local secure storage. The research presents ways to combine these algorithms to achieve a balance between performance and security. In particular, a process of pre-encryption of the private key using AES with the subsequent use of RSA for secure storage of encrypted fragments is proposed.
The practical part of the work demonstrates the effectiveness of the proposed methods. The comparison shows that AES works approximately five times faster than RSA, but RSA has much greater resistance to attacks. The use of parallel processing reduces the time for encrypting keys compared to serial data processing. The proposed methods are promising for use in financial, medical and other areas where a high level of protection is required. They demonstrate better resistance to attacks, reducing the risk of unauthorized access compared to traditional methods. The use of these approaches allows to significantly improve the security of storing private keys. Tabl.: 1. Refs: 13 titles. |

Досліджено способи захищеного зберігання приватних ключів акаунтів у блокчейн-мережах, зокрема, методи симетричного (AES) і асиметричного (RSA) шифрування. Безпечне зберігання приватного ключа є критично важливою задачею, оскільки компрометація ключа може призвести до втрати активів користувача і значних збитків. Акцентовано увагу на вдосконалених підходах, таких як фрагментація ключа, паралельне шифрування та комбіноване використання алгоритмів AES і RSA.
