Extended Validation Certificate **//


 * Extended Validation Certificates ** are recognized web authorization method that utilizes cryptography, a //PKI// technology.

EVC is a unique X.509 certificate that adds a level of security to online secure data transfer by requiring more information from the “requesting entity”. // Cryptography, // in modern terms is the study and/or practice of disguising information using a combination of mathematics and computer science. (cryptology; derived from Greek κρύπτω //kryptó// "hidden" and the verb γράφω //gráfo// "to write" or λέγειν //legein// "to speak") PKI or //Public Key Infrastructure//: a form of cryptography that designates “public keys” to specified identities, through the use of **digital certificates**. These //public keys// are a result of asymmetric cryptography where a user has two keys that are mathematically linked. The keys that are generated are a **Private** and a **Public** key. ( //See Figure 1// ) The public key is widely distributed while the private key is kept private. Key agreement is a method in which the device communicating in the network establishes a shared secret between them without exchanging any secret data. In this method the devices that need to establish shared secret between them exchange their public keys. (//See Figure 2)// - Anoop MS (2007).
