Authentication Solution :

Digital signatures :

Digital signatures are nothing but a cryptographic (encrypted) signature assurance scheme that lets both parties (sender and receiver) trust an electronic document and treat it as valid and tamper-proof as long as the said document stays in an electronic format.

To get technical, according to ISO/IEC 7498-2, a digital signature is defined as “data appended to, or a cryptographic transformation of a data unit, that allows the recipient of a data unit to prove the source and integrity of the data unit and protect against forgery.”

Digital certificates for machines :

It’s not just individuals who need to be authenticated. Servers need to prove their credentials too. That’s where a digital certificate comes into the picture, ensuring that the information sent to and received from a Web server is authentic, and that the Web server in question can be trusted. It can be trusted since it is verified by an independent source known as a certificate authority. The role of the certificate authority is to ensure that the system on either side can be trusted.
A Certification Authority (CA) issues certificates and stands responsible for them. The CA signs these certificates. This enables users to know which CA created each certificate. The signature also ensures that a third party has not altered or corrupted the certificate at any point of time.
In India, the Indian IT Act authorises the Controller of Certifying Authorities (CCA) to licence and regulate the working of CAs, who, in turn, issue digital signature certificates for electronic authentication of users.
At present, the organisations acting as licenced CAs are the National Informatics Centre, Customs and Central Excise, Institute for Development & Research in Banking Technology, SafeScrypt, Tata Consultancy Services, MTNL and (n)Code Solutions.

IT Act 2000 :

The Indian Information Technology Act 2000 (‘Act’) came into effect from October 17, 2000. The Act is by and large based on the United Nations Commission on International Trade Law (UNCITRAL) model law on electronic commerce.
The objective of the Act is to provide for legal recognition of electronic transactions and digital signatures. Section 5 of the Act gives legal recognition to digital signatures. Digital signatures have been legalised in India since 2000. However, since then, hardly any provisions of the Act have been implemented, except for the appointment of the Certifying Authority which took place in 2001.
