As the ever-developing digital world progresses, we find that an individual's privacy is getting compromised. Cryptography is a science that gives the solution to protect your privacy. It is a specialized field that needs expert guidance. As the burst of information threatens the peace of our students, online assignment help for cryptography homework seems to save the day for many budding computer scientists. Here is all you should know about cryptography, what you need to know, and from where you can get quality assistance.

What Is Cryptography?

Cryptography is a special branch of computer science that teaches students to encrypt a document. Cryptographers tend to put a security key to different documents and programs to ensure they don't get stolen or hijacked. In earlier times, cryptography was considered essential for military uses as it assisted in the transmission of sensitive information secretly without being hacked in the middle. However, in today's world, it has become a common action to protect any file with a password. You can also see the example of media-related files like music, movies, and videogames. The production companies encrypt these files to ensure that the data is only accessible to a limited set of systems or till a limited time period. Similarly, in internet transactions also, encryptions play a vital role to make sure the data that is transferred is properly secured. However, it is important to know that the only way any cryptographic algorithm works is through proper implementation of it. Otherwise, it is easy for expert hackers to decrypt the code.

Let us delve into the details of why we need cryptography.

Why Do We Need Cryptography?

Cryptography in the present world has become extremely important and common. Even a simple task of sending a WhatsApp message or an email is secured with encryptions. This is to make sure the cyberworld is a safe place to explore and experience for a common man. Here are the reasons why we need modern cryptography.

  • It ensures authentic transactions. Since cybersecurity is a major issue these days as hackerscan easily forge digital signatures, genuine encryption ensures safe transactions through the internet.
  • It ensures Digital Rights Management as it controls free access to satellite and cable TV along with movies, video games, etc.
  • It also ensures network securitysothat any information transmitted between connected computers is not intercepted by any middle server, thus making sure that any virtual transaction is safely carried out.

When Do We Need to Use Cryptography

The purpose of using cryptography is clear, to work in a secure cyber world without the fear of personal, official, or state information getting hacked or stolen. This section will discuss when cryptography is used. Encryption is used:

  • to validate user's identity;
  • to maintain ultimate confidentiality of data;
  • to ensure non-repudiation;
  • to manage that any data transmitted remains unchanged.

Different Cryptographic Techniques

There are various cryptographic techniques used depending on the nature of security required.

Caesar Cipher and EnigmaOne of the earliest forms of cryptographic technique, it is named after the Roman emperor Caesar, as it is believed that he used a certain trick to encode the messages he sent to his soldiers in times of war. This technique used simpler methods to encrypt which were easy to decrypt. Enigma was a machine that built upon the concept of Cesar Cipher. The Algorithm used to encrypt any data is also simple to decrypt however, the life of a cryptographic algorithm is only 24 hours, thus, posing a new challenge to the hackers every day.

1. Public-key cryptography

Two cryptosystems work together to formasymmetric encryption to ensure both sender and receiver are securely connected. ElGamal encryption is used for this technique.

2. Private-key Cryptography

Both sender and receiver use a single code for encryption and decryption of messages. Since the sender has this private key, the receiver will only be able to decrypt once the sender shares the code with the receiver.

3. Hash Function

This technique ensures that no malware is able to intercept or tamper with any message.

4. Post-Quantum Cryptography

Quantum computing systems serve as a prospective threat to the security of the cyberworld. However, research on post-quantum cryptography seems to be able to give the world some hope. It is nearly impossible to discuss this aspect in a limited-length article, yet if you wish to learn about it in detail and clarify some of your basic concepts about cryptography, feel free to contact our specialized team of cryptography experts, who are ready to help you any time.
