Trust is the common issue of concern while dealing with any business or professional circumstance. Same case applies while creating, signing and verifying electronic signatures. One must be sure about the legal and authentic identity of the user related to a certain digital signature.
All this procedure of creation and authentication needs a full fledge platform to perform these action. Here at this step we include PKI infrastructure, as it gave a combination of hardware and software services through which one can create, sign, authenticate, convert, transact, verify and validate a digital signature and also assure the legal identity of the owner regarding any digital certificate.
Digital certificates are like an authentication key allotted to a signer. This key represents the fact that certain signer is valid and authentic and could work with professional business entities. While on the time of issuance all digital certificates are allotted with their expiry date and time either it is after some months or after some years. Any certificate can be revoked due to which we need to be careful whenever we go for having an e-business deal or transaction. Before having a deal, one needs to sure about the current status of digital certificate either it is valid or not. For this purpose a service is used which is known as Validation Authority.
The validation process starts by having OCSP requests validation ses which are then sent towards the VA. VA tjem create a proof of validation by sending an OCSP response ovide OCSP Validation Proofs. Through these proofs (OCSP response), relying parties assure the validation of desired certificates. VA services are good enough to supWport different features in a valuable manner. Generally VA services should be very scalable to use, compatible with all system requirements, cost effective by completing the task in minimum expenditures, easily manageable and configurable, in complaint with all essential PKI- Standards, remote in nature (easily adjustable at any location) and secured by having certified cryptography standard FIPS 140-2.
After the validation all business entities can use the certified electronic ids, electronic passports, electronic payment methods, and electronic credentials and can have e-transactions. Third party certification & validation is really helpful for all type of professional entities who want to establish their network on web interface and are concerned about the authenticity of their dealers because third party VA assures their service users that all their requested certificates and credentials will be checked properly without any fault and will meet all the security needs.
Normally third party validation authority supports various platforms such as Solaris 8 and 10, Microsoft Windows 2003, 2008 and XP. Along with these operating systems it is also supportive with various databases such as Oracle 9i and 10g, Microsoft SQL 2005 and 2008 while supportive security modules are Safe Net, Luna, AEP Keyper 1.4 and 2.3.
In this fastest, technological era no one has the time to have authentication and validation manually by paying lots of money on this procedure, so companies and professionals prefer to use VA services for a fastest, secure and valid result also by assuring minimum cost.
