What is digital signature technology?.
A digital signature technology is a technique that is based on mathematical formula to bear out the legitimacy of a message, software or digital content.
What is the use of it?.
Digital signature technology is very useful to resolve the issues of tampering and impersonation in digital communication. This can also helpful to detect any kind of digital content fraud and theft. It will also strengthen security system of digital communication.
There are several countries that are using digital signature technology to publish official electronic documents. In several countries, digital signatures have the same legal importance as same as the traditional signed documents. The United States Government Printing Office publishes electronic versions of the budget and other docs with digital signatures.
How does a digital signatures works?.
Digital signature works based on cryptography, also known as asymmetric cryptography. To make a digital signature, email program software creates a one-way hash of the electronic data and after that it encrypts hash. The reason for encryption is that the hash function can convert arbitrary input into a fixed length value.
Capture digital signature in various domains.
The personal computer and the Internet have provided many useful services to both professionals and the general public. However, security remains a key factor that could limit their further growth potential.
The cryptographic application has a great potential in protecting security of information transmitted over the Internet. A better security infrastructure is helpful to support deployment of the technology but it is expensive too.
