A digital certificate function is similar to the function of identification cards such as passports and driving licenses. Digital certificates are issued by recognized Certification Authorities (CA). Figure . Digital Certificates Common digital certificate systems are X.

SSL is a hybrid encryption protocol for securing transactions over the Internet. The SSL standard was developed by Netscape in collaboration with MasterCard, Bank of America, MCI and Silicon Graphics. It is based on a public key cryptography process to ensure the security of data transmission over the internet. Its principle is to establish a secure communication channel (encrypted) between a client and a server after an authentication step.
. . Authentication protocols At present, there are two kinds of security authentication protocols widely used in E-Commerce, namely Secure Electronic Transaction (SET) and Secure Sockets Layer (SSL). Secure Electronic Transaction Secure Electronic Transaction (SET) is a security protocol for electronic payments with credit cards, in particular via the Internet.
SET was developed in by VISA and MasterCard, with the participation of GTE, IBM, Microsoft and Netscape. The implementation of SET is based on the use of digital signatures and the encryption of transmitted data with asymmetric and symmetric encryption
