Current approaches to e-commerce security

In this section we review the approaches used by e-commerce sites to achieve security using 

the techniques described above.

Secure Sockets Layer Protocol (SSL)

SSL

 is a security protocol used in the majority of B2C e-commerce transactions since 

it is easy for the customer to use without the need to download additional software or a 

certificate.

Digital signatures

A method of identifying 

individuals or companies 

using   public-  key 

encryption.

Certificate 

and certificate 

authorities (CAs)

A certificate is a valid 

copy of a public key 

of an individual or 

organisation together with 

identification information. 

It is issued by a trusted 

third party (TTP) or 

certificate authority (CA).
