A digital signature is a cryptographic system created to protect the accuracy and integrity of digital messages or documents.
What is Digital Signature?
Digital Signature refers to unique codes that represent the owner of the address and verify the data in transactions performed in the digital environment. It can also be defined as the versions of wet signatures created with mathematical codes. However, Digital Signature has a more secure structure than wet signature.
Digital Signature is often used to enforce electronic signatures. However, not all electronic signatures use a digital signature. An electronic signature can be defined as any mark placed on an electronic document. A digital signature creates an electronic fingerprint with the encryption it uses. Digital signatures are more complex and reliable because they use public-key encryption and asymmetric cryptography. Public key cryptography helps to generate a code that proves that the data transmitted between the sender and the receiver has not changed. In this way, possible security violations can be detected and the message is transmitted securely to the recipient.
Digital Signature is in many ways equivalent to traditional handwritten signatures. Digital signatures are often used in software distribution, financial transactions, contract management software, information security, and other situations where fraud detection is important.
Creating a Digital Signature
Digital Signature creation proceeds in three stages in the cryptocurrency ecosystem; Hash, signing and validation.
Hash is the process of obtaining a new version of the message to be sent by shortening it in a unique way. Hashing can be defined as the creation of a summary value by passing the data or message through the hash algorithm.
How to Sign a Digital Signature?
The second step is signing. In this step, the person who created the document or sent the message signs the document. The hash, encoded using the secret key, is used as a digital signature. The digital signature is attached to the message and the message is sent to the recipient.
How to Get a Digital Signature?
The receiver decrypts the encrypted hash using the sender’s public key. The third and final step is to verify signature validity. In this process, the document is checked with the public key. If the two “hashes” are the same, it is confirmed that this message belongs to the sender and that the message is unchanged.
Where is Digital Signature Used?
Digital Signature (digital signature) ensures that the holders of cryptocurrencies are carried out securely when making transactions in blockchain systems. Digital signature is used to approve digital documents and perform financial transactions. Digital signature is used in official documents and business agreements in the field of law, and to prevent fraudulent prescription and health record frauds in the field of health. Digital Signature (Digital Signature), which is used in many areas such as ensuring the security of internet communication systems, saves time and cost, and also contributes to the environment.
What are the Advantages of Digital Signature?
Thanks to the mathematical encodings used in the infrastructure of the digital signature, the security level is much higher than the traditional signature methods. The digital signature, which is used today to meet the high security need, provides the integrity, authentication and non-repudiation of the information or message.
A digital signature has a structure that shows the source, status, confirmation of the signer, and the security match between the receiver and the transmitter. However, it provides protection against false identity formations that are likely to occur in digital communication. In addition, those who use digital signatures save time and cost, while contributing to the environment.
