In today's world of technology, there are no islands of data but continuous movement of information, ideas, conversations, goods and products. But there needs to be a foundation of trust that enables the honest exchange of these items. If we can manage trust in every exchange through different protocols to verify the truth of facts in any exchange, we can then have an internet of trust. We will be demonstrating this trust by playing the classic game of Battleship between two players Alice & Bob that have just meet online for the first time.
We will be implementing cryptographic hashing algorithms and digital signatures in order to verify the data between our two players to be true, but to also maintain the integrity of the moves being played. This will help to prove that our data has not been modified by an unauthorized entity or adversary …show more content…
To ensure this is done we will create a cryptographic 256-hash function containing a string of digits unique to each player. We will be able to protect the integrity of the data of Alice and Bob and also detect if changes or modifications where made to our message. Please see Figure 1. Figure 1:Cryptographic Hashing algorithm (SHA-256) created from input text will allow any player to store their actual move to prove no other party or adversary created the move.

Part 2: Authenticity of Signatures from Source and Destination
We will now need to prove and identify the moves Alice and Bob make to ensure they will not be able to deny their involvement with the moves they play representing their own information through their hashed message being sent to the source and destination locations. We will do this by creating digital signature. Please see Figure
