Unhackable Systems Are a Myth

Many people believe that there exist a way to make a computer or electrical device unhackable, but in reality what cyber security does is slow down a hacker through the creation of a large complicated math problem. Since, the algorithms that are used to encrypt systems are technically complex math problems, if a person has a computer do the calculations eventually it will find the solution to pass through the security system. Even though there does exist certain types of cryptography techniques such as One Time Pad and MD5 encryptions, usually the systems used by the public are not this secured and would not take as much computer power to decrypt them.  

There are two major things currently being researched that can completely cripple current cyber security. The first is one of the six unsolved mathematics problems, known as P versus NP. The idea behind P versus NP is that if a computer can verify that a problem has a solution then it should also be able to find the solution just as fast as it verified it. Since all encryptions are already known to have solutions this means that a computer that is able to verify that a certain encryption algorithm has a solution, it would also be able to crack that solution with no problem. The only thing that a P versus NP computer would be able to do is find the solution to the encryption algorithm, a hacker would still have to write a code that can apply the solution and get into the system. Whoever is able to solve P versus NP would be able to earn one million dollars, but in reality who would sell an undetectable hacking software.  

Something else that would easily be able to overcome current security is quantum computers. Most security systems are technically meant to slowdown or make it difficult for a hacker to get into a system, quantum computers would easily be able to get around most security systems since quantum computers would be working on a level way above those that are silicon based. One of the main goals of quantum computers is to make a system that is extremely efficient and extremely fast when compared to the technology we have today. A hacker with a quantum computer would easily be able to run the calculations and software needed to hack systems that even have state of the art security systems.  

Many people believe that certain operating systems are unhackable, but in reality that is a lie, since hackers target the systems that are more widely used by the general public such as Windows and Mac. But there does exist one way to make a system almost unhackable. For a computer to be almost unhackable a person would have to get a new computer and make sure to always have the internet disconnected at all times, it might even be better to take out the network chip. By not connecting to the internet a user would not be able to download viruses and malicious software to their systems. All updates would have to come from a USB that the user knows where it has been connected and have gotten the updates from official websites. The only way that a computer like this could be hacked is if a hacker physically accesses the computer but without the internet the files on the computer would be safe. Other than this all electrical systems would be hacked no matter what type of security has been placed to prevent it.
