Blokzincir Tabanlı Donanımsal Cüzdan ve Akıllı Kartlar

Year 2021, Volume: 4 Issue: 1, 37 - 48, 15.06.2021

Abstract

Kripto para transferi için gönderen ve alıcıya ait ortak anahtar denilen adreslerin olması gereklidir. Göndericinin adresi, alıcının adresi ve gönderim miktarı gibi bilgilerin olduğu işlemler, birbiri ardına bağlı blokların içerisinde belli bir sisteme göre tutulur. Her adresin yani ortak anahtarın benzersiz gizli bir anahtar karşılığı bulunmaktadır. Kripto para işlemleri için bu özel anahtarlar ile atılmış imzalar kullanılır. Mahremiyet söz konusu olduğu için kripto para transferinde birden fazla adres yani anahtar çifti kullanmak önemlidir ve önerilmektedir. Bu anahtarların yönetimi ve depolanması cüzdanlar sayesinde sağlanır. Çevrimdışı cüzdanların direkt olarak internet erişimi yoktur ve daha güvenlidir. Bu makalede çevrimdışı cüzdan çeşidi olan blokzincir tabanlı kripto paraların erişimine ve harcanabilmesine olanak sağlayan anahtarların tutulduğu donanımsal akıllı kart cüzdan konusu işlenmiştir. Anahtarın üretimi ve depolanması için hiyerarşik ve deterministik bir yöntem sunan BIP-32, BIP-39 ve BIP-44’e bu çalışmada detaylı olarak yer verilmiştir. Yerli ve milli akıllı kart işletim sistemi olan AKİS’in v3.0 sürümünde kimlik, pasaport, ehliyet, e-imza, bilet gibi uygulamalar tek bir kart içinde toplanabilmektedir. Bu sürümle birlikte kartın içinde olan uygulamalardan biri de cüzdan uygulamasıdır. Bitcoin kripto para transfer işlemlerini yapabilecek özellikte tasarlanmıştır. AKİS cüzdan BIP-32, BIP-39 ve BIP-44 ve eliptik eğri kriptografik işlemlerini yapabilecek şekilde geliştirilmektedir.

Hardware Wallets and Smart Cards for Blockchain Platforms

Year 2021, Volume: 4 Issue: 1, 37 - 48, 15.06.2021

Abstract

For cryptocurrency trading, the addresses of the sender and the receiver, called public keys, are required. Transactions involving information such as the address of the sender, the address of the recipient and the shipping amount are kept according to a certain system in blocks that are connected one after another. Each address, the public key, has a unique secret key equivalent. Signatures signed with these private keys are used for cryptocurrency transactions. Since privacy is at stake, it is important and recommended to use more than one address in cryptocurrency transfer. The management and storage of these keys is provided by wallets. Offline wallets do not have direct internet access and are more secure. In this article, the topic of a hardware smart card wallet that holds keys that allow access and spending of blockchain-based cryptocurrencies, which is an offline wallet type, is discussed. BIP-32, BIP-39 and BIP-44, which offer a hierarchical and deterministic method for key generation and storage, are given in a detailed way. In the v3.0 of AKİS, the national smart card operating system, applications such as identity, passport, driver's license, e-signature and ticket can be collected in a single card. With this version, one of the applications included in the card is the wallet application. It is designed to handle Bitcoin transfer. AKİS wallet is developed to be able to perform BIP-32, BIP-39 and BIP-44 and elliptic curve cryptographic transactions.
