E-num

E-num is an up-to-date authorization system ensuring enhanced information security. The protection is achieved by both cryptographic capabilities and at the architectural level. The secret data access key is stored on the user’s mobile phone, not on the computer, thus allowing usage at multiple computers and excluding the risk of the key being corrupted or stolen by trojans or other malware.

Registration

Upon user registration, a WAP link is sent to the number specified by the user. This link is used to download to the user’s mobile phone a Java application that contains a unique set of access codes (the application can also be sent by e-mail to be installed from the computer). Confirming successful registration at the service site, the user activates the received set of access codes and can further use it as a versatile authorization tool ensuring authorization at the sites of various services connected to E-num.

Authorization Procedure

Since a user doesn’t have to remember sophisticated passwords, the authorization system is quite user-friendly. The entire authorization procedure is implemented based on the Challenge / Response model.

The E-num authorization procedure is extremely simple:

• a user enters his / her e-mail on the secure access site page, after which the user is displayed a check digit;
• the user runs the E-num application on his / her mobile phone and enters the check digit. After that, the target digit (access code) is shown on the phone screen;
• the user enters the target digit in the authorization field on the site and receives access to the secure sections*.

Advantages

The key advantage of E-num versus its competitors is its cost efficiency for both product and service vendors and users.
To use the E-num authorization system on a store site, online service, or bank or corporate systems, it is not needed to deploy an additional authorization server, since all the required information is stored in the E-num database. Data exchange is implemented via a secure https connection based on interfaces supported by the E-num system. For authorization on systems connected to E-num, service customers use their mobile phones (the only requirement is Java support).
Users don’t need any special expensive devices. A set of access codes that is unique (for each customer) is coded into the mobile Java application.
