Hello Readers. Today we are presenting very important article for your competitive exams and MUST to know for every educated personnel. Yes! this is about Digital Signatures. Here you can check Introduction to Digital Signatures in Hindi.

What is Digital Signature

An introduction to Digital Signatures
Digital signatures we can say that it is almost equivalent to traditional handwritten signatures. Digital Signatures are legally admissible in a Court of Law, as provided under the provisions of IT Act, 2000. This is modern high used term in information technology. Simply, verifying digital information known as digital signature that means technique is used to verify Digital information. It is often used to implement electronic signatures. This is important that Digital Signature have legal significance. It is used employ asymmetric cryptography. We also discuss about cryptography in separate article.
जिस प्रकार हम कागज पर हस्ताक्षर करके ये प्रमाणित कर देते है कि ये मेरे हस्ताक्षर है और इस प्रकार के हस्ताक्षर और कोई नहीं कर सकता है और अगर करता है तो वे हस्ताक्षर मान्य नहीं होते है और legally स्वीकार्य नहीं किये जाते है। अब बात आती है physical hand signature से हटकर कम्प्यूटर पर किसी दस्तावेज के लिए इलेक्ट्रोनिक रूप से किये गये हस्ताक्षर की।

Important Points to be remember digital Signature

Here we Easy Explained Digital Signature-
  • The authenticity of many legal, financial and other documents is determined by the presence or absence of an authorized handwritten signature.
  • Various methods have been devised to solve this problem, but the use of ' Digital Signature' is definitely the best solution amongst them.
  • A digital Signature is nothing but an attachment to any piece of electronic information, which represents the content of the document and the identity of the originator of that document.
  • A digital Signature main purpose is saving time and paper.

What Algorithms scheme used in a digital signature

Three types of algorithms scheme used in a digital signature like.

(i) Key generation algorithm- A key generation algorithm that selects a private key uniformly at random from a set of possible private keys. The algorithm outputs the private key and a corresponding public key.

(ii) Signing algorithm- A signing algorithm that, given a message and a private key, produces a signature.

(iii) Signature verifying algorithm- A signature verifying algorithm that, given the message, public key and signature, either accepts or rejects the message's claim to authenticity.

यहां हम आपको keys के बारे में कुछ जानकारी बताते है-
दोस्तो internet पर authentication के लिए key प्रयोग किये जाते है। जो private keys और public key के रूप में हो सकते है। जिस प्रकार हम कागज पर हस्ताक्षर करके ये प्रमाणित कर देते है कि ये मेरे हस्ताक्षर है और इस प्रकार के हस्ताक्षर और कोई नहीं कर सकता है और अगर करता है तो वे हस्ताक्षर मान्य नहीं होते है और legally स्वीकार्य नहीं किये जाते है। अब बात आती है physical hand signature से हटकर कम्प्यूटर पर किसी दस्तावेज के लिए इलेक्ट्रोनिक रूप से किये गये हस्ताक्षर की। ये कैसे तय होगा की ये इलेक्ट्रोनिक हस्ताक्षर जिसने किये है वे सही है। तो इसके लिए public key encryption और Private key encryption or secret-key encryption का प्रयोग होता है।

Private key encryption or secret-key encryption
दोस्तो Private key encryption or secret-key encryption एक बहुत ही simple method है। मैं कुछ फाईल आपको भेजना चाहता हंू। आपको यह पता है कि ये जो फाईल है वो मेरी तरफ से ही आई है। तो यहां हम Private key encryption का उपयोग कर सकते है। मैने उस file को किया। Encryption is the most effective way to achieve data security. To read an encrypted file, you must have access to a secret key or password that enables you to decrypt it. Unencrypted data is called plain text ; encrypted data is referred to as cipher text.

Public key encryption
A cryptographic system that uses two keys -- a public key known to everyone and a private or secret key known only to the recipient of the message. When John wants to send a secure message to Jane, he uses Jane's public key to encrypt the message.
