Zero Day Found Universal Turing Machine

A theoretical computing device Turing machine was invented by English mathematician and logician Alan M. Turing in 1936. It was specifically devised for the computing of real numbers. The machine is used to accept recursively enumerable languages. Its working is dependent on a tape of infinite length on which the operations of reading and writing can be carried out.

The Universal Turing machine was the first ever constructed by computer architecture. According to a Swedish professor of computer science, the zero-day found Turing machine has a random code implementation flaw.

Moreover, an expert professor of KTH Royal Institute of Technology Mr Pontus Johnson has also claimed that this is not among the common machines because there was no actual world application to discover this Turing machine. He also added that the late Marvin Minsky who explicitly referred to the functioning of zero-day Turing machines co-focused on the machine that does not exactly exist.

When he started working on the zero-day found Turing machine, he believed that it is the most simple and theoretical model of a computer. He also deceive his wordings about the execution program of Minsky’s universal Turing machine and he wrote that the absence of input validation is an advantage for the machine.

Why is the universal Turing machine important?

In the beginning, Turing never come up with an actual machine rather they came up with an abstract model for all other machines. In other words, it can be said that any algorithm of other machines can be created on a Turing machine.

Therefore, a Turing machine can run all operations starting from the basic addition of “2 + 2” to all the latest Assassin’s Creed. The thing is that it requires a lot of tape for such carrying out. After all, it is a theoretical machine then it needs tape to describe computers.

Before any application of the Turing machine, we did not know the exact limits of algorithms and their computation. That is why it is considered an amazing innovation to answer some basic mathematical questions. Now, the process of the Turing machine is the basis of all computers we use today.

This is cool to read about computers for all your general purposes but the fact is that it was written by Turing machine before any programmable computer machines in 1936. It was a time when the computations were done by a person and not by a machine, so a brilliant person was the machine. At that time opinions about computers were that they are built-in for just one purpose computation. Alan. M. Turing believed otherwise that you could create a single machine that can be programmed to do any task. His thinking came up for true for all of us and we are using those machines now in our daily routine.

Zero-day found Turing machine runs on basic programs!!

It is a tap-based Turing machine that reads and runs the basic programs depicted by Minsky specification and an imitated tape. According to the instruction written on the tape, when the head of the tape reader is moved left or right across it then one line of alphanumeric text is entered.

Users of the machine can enter their data at the beginning of the tape, and the concept of the working of the machine is that users are not allowed to change the software on which it runs. after putting the input. Indication for the end of input by the user is a single number, and it will execute whatever is read using the parameters.

The working technique of Johnson was easy he gives the character “input ends here” in the input box and then added his software after it. When the machine runs the input then at that time the projected program is skipped over and this resembles an insertion of a test SQL.

Johnson also declared that it would seem to be impractical to integrate security aspects from the beginning of the functioning of the machine if the Universal Turing Machine was the originator of all computers in the techno world.

Is zero-day found Turing machine real?

This is not a real machine, it’s concept is based on a mathematical model and state machines such as Turing machine automata or combinational logic. Its concept of implementation is purely conceptual.

A professor of computer science from Sweden has discovered a random code implementation in the machine. The code is one of the earliest computer designs thus, he admits the Turing machine has “no real-world allusions”.

Properties of a Zero-day found Turing Machine

A Turing machine is a finite state machine with unlimited memory and was capable of simulating common computer problems that we use today. Problems are described in diverse languages. The Turing machine simulator can identify and settle different kinds of languages as well as problems. For instance, there is a language of all strings made up entirely of 1’s such as “1”, “111111”, “111111111”, and so on. To computer these types of strings a Turing machine can be created by just writing a program that makes the device write 1 when the head moves to the right, so, the head of the machine will always move to the right as per the instructions. It has numerous beneficial properties:

Ability to Recognise

A Turing machine is capable to identify the language and thus accepts an input string in that language. It rejects taking the input string if that is not in any language. It means in case the string being input is not in the language then the machine does not halt rather it rejects the input and continues with its proceedings.

Capability to decide

Along with the ability to accept and reject the language and non-language inputs respectively, it shows that the Turing machine model is decidable in taking inputs from outside.

External memory

Alan Turing’s zero-day found Turing machine has an external storage space that remembers a long series of subjective input. Moreover, it has a boundless memory aptitude.

Easy reading of the input

Turing machine model has the capacity of easy conversion of the input at left or light on the tape.

Output generating property

A Turing machine can generate a certain output that is completely based on its input. Sometimes the requirement arises that the same type of input is needed to produce the output. Thus, in the Turing machine, the difference between the input and output has been eradicated. Hence, there are a common set of alphabets that can be used for the processing of the Turing machine.

7-tuples of a Turing machine!!

Alan’s Turing machine model is expressed as a 7-tuple (Q, T, B, ∑, δ, q0, F) where:

  • Q tuple is a set of head states and is finite in number.
  • T is the symbol that can be written on the tape of the Turing machine.
  • B is a blank cell for the tape symbol and initially, each cell is filled with B except for any input.
  • ∑ is a tuple that is for the input alphabet.
  • δ is a conversion function that maps Q × T → Q × T × {L, R}. Depending on its present state it will move to a new state. It is symbolised to change the tape symbol to move the head pointer to either left or right.
  • q0 is the primary state of Alan’s Turing machine
  • F is the set of final states. A string of input is accepted when any state of F is reached.

How does the zero-day found Turing Machine work?

It is already mentioned that the working of the machine depends on the tape and mainly the machine has three parts:

  • An endless roll of tape. On this tape, symbols can be written, erased, and rewritten with different symbols as well.
  • The Head is another significant component of the Turing machine that does the writing. The head can move the tape up and down to make it possible to write, erase or re-write symbols on it. It is similar to the head in a computer’s hard disk.
  • Third, the most important component is the memory part of the machine which is the state register. This component holds the current state of the Turing machine in which it is.

All in all, a tape is used to write a symbol and it moves from left to right. Although it has a limited set of actions still it is capable to do all kinds of functions like a programming language.

There’s a table of instructions for the Turing machine to tell what action to take and when. It consists of 5 columns. The first two columns are to find out the diverse arrangement of machine inputs. The first column checks the current state of the machine, the second column is to check the symbol that is below the head of the machine at present.

The next three columns of the table are to verify the actions carried out by the machine for the first two columns. These are for the next symbol to be written on the machine, which tells where the head should move and what will be the next state.

Arrangement of machine InputsActions carried out by the machine
The current state of the machineThe current symbol below the headAction takenMovement of the headNext state of the head
A0Write 1RightB
A1Write 0RightB
B0Write 0RightA
B1Write 1RightA

To illustrate the functioning of the Turing machine, if the current state is “A”, and the symbol below the head is “0”, then the machine should write “1” in that place and the head will move towards the right, to get the next state “B”.

We have given the instruction table here and if you follow this then you’ll see that for state A of the machine all 0s are replaced with 1s and 1s with 0s. In addition, for state B, the 0s and 1s will stay the same. In addition to this, state A will always change to B and vice versa. This operation leads to the inversion of every alternative symbol of a string. So for “1111”, you’ll get “0101”.

Applications of Zero-day found Turing machine!!!

Turing invented the machine to formalize the notion of computability to handle a basic mathematics problem. After that, the machine was used for many applications. Let us look at the various applications of the Turing machine.

How did Alan Turing’s machine break the Enigma code?

German armed forces used a kind of enciphering machine called Enigma to send messages safely and soundly. The main focus of Alan M. Turing was to crack the ‘Enigma’ code. Although numerous mathematicians had worked out this motive for how to read Enigma messages, they had shared this information with the British. After hearing this the Germans started changing their cipher system on daily basis to enhance the safety of its armed forces. This daily activity of Germans made it difficult for mathematicians to understand their Enigma code.

An application of the Turing machine played a key role in this. Gordon Welchman invented a fellow code-breaker machine known as the Bombe. This device considerably assisted the code-breakers in their work reduction. From mid-1940, all signals of the German Air Force were being read at Bletchley and the intellect gained from them was helping in the war efforts.

Hut8, Bletchley park for German naval communications

Turing machine also worked to decode the complex communications of the German Navy. This had overcome many others at Bletchley. The scene was that in the associated shipping process German U-boats were imposing heavy losses, and it became crucial to understand their signals. With the help of material that was captured in decoding the Enigma code, Turing worked for a new development called ‘Banburismus’, with that from the year 1941 the naval Enigma messages were able to be read.

The role of Turing was critical to helping the Allies at the time of the Atlantic battle. A. Turing headed his ‘Hut 8’ team at Bletchley, which processed the cryptanalysis of all German naval signals. This meant that despite 1942 similar convoys could be directed away from the German U-boat.

Development of new devices named Turingery and Delilah

Another application of the Turing machine is ‘Turingery’ which was developed in 1942. It was again a complex code-breaking technique at Bletchley to understand the ‘Lorenz’ cypher machine. It was a strategy to convert the significant messages of Bletchley for the linked war effort.

For the progress of this method in December 1942, Turing travelled to the United States. His purpose in visiting there is to advise US military intelligence to use Bombe machines and also to share his knowledge of the German Enigma code. During his visit, Turing also saw the development of a secret speech converting system by Americans. Then in Match 1943, he returned to Bletchley and continued his work in cryptanalysis.

Later in the war, he did work on the development of a speech scrambling device name ‘Delilah’. Then in 1945, he was awarded an OBE for this Turing machine in automata in his wartime work.

Bequest of Turing machine

In 1952, in Britain Alan Turing was arrested for an illegal act of homosexuality. He was found guilty but he accepted the chemical castration and how he avoided a prison sentence. Later, after 2 years of his hormones-related behavior in 1954, he was found dead from cyanide toxins. An investigation lined his death as a suicide.

His gift of zero-day found Turing machine did not fully come into the limelight until long after his death. Rather, his impact on the computer science department has been recognized. For this acknowledgment there is the highest tribute to Alan Turing is the annual ‘Turing Award’ in the computer science industry since 1966. Still, until 1970 his development of Bletchley Park, cracking the Enigma code was kept secret.

Moreover, the complete story of his progress was not well-known till the 1990s. It is just an estimation that his developments and applications of the Turing machine and code-breakers progress concise the war by several years. The positive side was that all of the above applications of the Turing machine saved numerous lives during the war and also helped to settle on the path and conclusion of the variance.
