The U.S. Navy seeks to leverage emerging technologies to manage massive amounts of data from multiple geographically separated systems. It is aware of the importance of data usage and data transfer in supporting its operations. Data management requires a data transfer system that is safe, fast, and scalable. Autonomous Navy Unclassified Software Distribution (ANUSD) is an application for delivering software to all nodes on the Navy's enterprise network based on blockchain technology. Blockchain...

Although initially introduced to support the Bitcoin cryptocurrency, many blockchain technology applications have been envisioned. As a result, blockchain platforms have been created and others are under development. The Department of Defense (DoD) needs blockchain platform testbeds so that applications beyond cryptocurrency can be explored. To solve this problem, we decided to construct a small blockchain testbed. We developed criteria to aid in selecting a blockchain platform for use in a...

The process of tendering, even if it is paper based, it raises several legal issues. The main concept of tendering is to befair and transparent and requires trust between both the tenderer and bidder. The use of electronic medium in tendering raises the need for not onlylegal issues but also the security threats that come up when moving to an open network environment.

A Blockchain is defined as a distributed database which consists of records, or public ledgers of all the transactions or digital events executed and shared among participating network. In this each transaction in the public ledger is verified by consensus of a majority of the participants in the network. As soon as the information is entered, it can never be erased. The Blockchain contains a verifiable record of every single transaction ever made. [9]It was developed firstly for Bitcoin as a...

As the threat of cyber attack grows ever larger, new approaches to security are required. While there are several different types of intrusion detection systems (IDS), collaborative IDS (CIDS) offers particular promise in identifying distributed, coordinated attacks that might otherwise elude detection. Even for this type of IDS, there are unresolved issues associated with trusting participants and aggregating data. Blockchain technology appears capable of addressing those issues. This thesis...

Traditional payment systems have standards designed to keep transaction data secure, but blockchain systems are not in scope for such security standards. We compare the Payment Application Data Security Standard’s (PA-DSS) applicability towards transaction-supported blockchain platforms to test the standard’s applicability. By highlighting the differences in implementation on traditional and decentralized transaction platforms, we critique and adapt the standards to fit the decentralized...

Blockchain is the underlying technology behind cryptocurrencies bringing together Merkle trees, Hashing & Distributed Architecture. Christopher Ellis explains. Note1 - At 6:46 when Chris is drawing the Merkle Tree, C would actually be duplicated and hashed with itself not with B. So you would get H(C - C) instead of H(B - C). Note2 - At minute 17, Christopher mentioned the mining reward halving at 21,000 bitcoins but meant 210,000 blocks. Public Key Encryption: https://youtu.be/GSIDS_lvRv4...

Blockchain is a technology for storing and managing sensitive data such as financial information, health records, and transactions. It is a decentralised, distributed public ledger that is maintained by the network of a verified group of individuals or nodes. All nodes need to reach an agreement on whether the data should be kept in the block to guarantee that the data are safe and no corrupt branches. Healthcare is one of the potential fields where blockchain technology can be implemented,...
