Authentication: An E-Digital signature provides a way to authenticate the identity of the signer of a document or transaction. This is important in situations where the authenticity of the signer’s identity is crucial, such as in legal contracts, financial transactions, or government documents.
Integrity: An E-Digital signature ensures the integrity of the signed document or transaction, meaning that the contents of the document have not been altered or tampered with after the signature was applied. This is important to ensure the accuracy and validity of the information being transmitted.
Non-repudiation: An E-Digital signature provides a way to prove that the signer of a document or transaction cannot deny having signed it. This is important in situations where disputes may arise, such as in legal or financial transactions.
Efficiency: E-Digital signatures can greatly increase the efficiency of document and transaction processing, as they eliminate the need for physical signatures and can be applied and verified electronically.
Overall, E-Digital signatures are an important tool for ensuring the authenticity, integrity, and non-repudiation of documents and transactions, while also improving efficiency in their processing.
A digital signature is a cryptographic technique used to verify the authenticity and integrity of electronic documents, messages, and transactions. They have been around for several decades and have a rich history. Here are some key milestones in the history of digital signatures:
In the early 1970s, Whitfield Diffie and Martin Hellman developed the concept of public-key cryptography, which laid the groundwork for digital signatures.
In 1976, Whitfield Diffie and Martin Hellman, along with Ralph Merkle, published a paper that described a digital signature scheme based on public-key cryptography.
In 1983, Ronald Rivest, Adi Shamir, and Leonard Adleman developed the RSA algorithm, which is widely used for digital signatures today.
In 1988, the Digital Signature Standard (DSS) was developed by the National Institute of Standards and Technology (NIST) in the United States. The DSS was based on the use of the RSA algorithm and provided a standard for the use of digital signatures in the US government.
In the 1990s, digital signatures began to be used in commercial applications, such as online banking and e-commerce.
In 1999, the Uniform Electronic Transactions Act (UETA) was passed in the United States, which provided a legal framework for the use of electronic signatures and records in commerce.
In 2000, the Electronic Signatures in Global and National Commerce Act (ESIGN) was passed in the United States, which provided legal recognition for electronic signatures in interstate and international commerce.
In 2004, the European Union passed the Electronic Signatures Directive, which provided a legal framework for the use of electronic signatures in the EU.
In 2008, the Adobe PDF format introduced support for digital signatures, making it easier for businesses and individuals to use them.
Today, digital signatures are widely used in many industries, including finance, healthcare, government, and e-commerce, to verify the authenticity and integrity of electronic documents and transactions.
A digital signature is a cryptographic technique used to verify the authenticity and integrity of electronic documents, messages, and transactions. It provides an added layer of security to ensure that the message or document originated from a specific sender and has not been tampered with during transmission.
Authentication: A digital signature verifies the identity of the sender and ensures that the message or document has not been forged or altered. This helps to prevent fraud and protects the integrity of the information.
Non-repudiation: A digital signature provides non-repudiation, which means that the sender cannot deny sending the message or document, and the recipient cannot deny receiving it.
Data Integrity: Digital signatures ensure that the content of the message or document has not been altered during transmission, ensuring the data’s integrity.
Legal Validity: Digital signatures are legally recognized in many countries and can be used in court as evidence. They are often used in electronic contracts, financial transactions, and other legal documents.
Overall, digital signatures provide a secure and reliable way to authenticate electronic messages and documents, ensuring their integrity and protecting them against fraud.
