Send SMS from Strong Authentication Server

To build a highly secure corporate IT system you can apply Strong Authentication Server as it provides two-factor authentication. Practically it means that one-time passwords are sent to mobile phones as SMS messages and users can logon only with these passwords. This solution assures a very high level of identity protection in the corporate IT environment. To employ this solution, you need an application that is able to provide SMS functionality. Such an application is Ozeki NG SMS Gateway that can be installed on your computer. This software product will forward your messages to the mobile network over a GSM modem or an IP SMS connection. By implementing Ozeki NG SMS Gateway you will ensure an easy way for sending one-time passwords as SMS messages. Read this article to find out how to adopt this solution in practice.

Fields of applications

Security is an essential issue in corporations as there are more and more attacks on corporate networks. As these attacks keep getting more advanced, prevention is becoming harder against them. Therefore, single-factor authentication (username and password) is not enough for protecting purposes any more. These user identity credentials can be easily lost or hacked. Strong Authentication Server provides strong authentication solution for these security problems though you can still improve its features to be more effective and secure.

To achieve a more efficient security system, implement a stable SMS gateway software such as Ozeki NG SMS Gateway into the corporate IT network to provide SMS functionality. This SMS solution allows to introduce one-time passwords that are sent as SMS messages to the cellphone of the user who wish to logon the system. This efficient method makes two-factor authentication possible. Two factor authentication means, that a user types in his password, then he receives an SMS text message to his mobile phone with a one-time security code and he needs to enter it to complete the authentication. In this way you can ensure that no unauthorized person will get access to your IT network and corporate data. The security of these passwords are improved further by the fact that they expire automatically after a short period of time if they are not used.

If you decide to implement this solution you will gain a stable, well-functioning and highly secure IT system based on Ozeki NG SMS Gateway. Below this page you will find a step by step installation guide on how to configure your system to achieve SMS extension.


To adopt this solution you will need a connection between the mobile network and your system. You can establish this connection in two ways: using an Internet connection or using a wireless connection by attaching a GSM phone or GSM modem to your PC. Please check this website if you need some help for your decision: Internet based SMS connections vs. GSM modem based (wireless) SMS connections.

Preconditions for Internet based connection to the Mobile network

To establish the connection between your system and an SMS service provider via the Internet, you will need these devices:

With this type of connection you will need an SMS service provider who provides access to its services and ensures Internet based SMS services. On our webpage we have collected some providers to help you in your decision: SMPP SMS Service providers. After you have decided which provider and which service is the most appropriate for you, you need to sign a contract and you will receive connection parameters from your provider. Once you got the necessary parameters you can setup your Ozeki NG SMS Gateway software.

Preconditions for wireless (GSM modem) connection to the Mobile network

With this type of connection all you need is a GSM modem or a GSM phone and you can join it easily to your PC with a data cable. The GSM device will be operated by your Ozeki NG SMS Gateway software and it will be able to handle SMS messaging wirelessly. You will need the following components to use this type of connection:

System architecture

After gathering all the prerequisites start to build your SMS system that will operate in the following way: With SA Server, you can enter your username and a password to log into the corporate system. A one-time password is generated by the strong authentication device using an encrypted algorithm. This generated password will be sent out as an SMS message to Ozeki NG SMS Gateway through a HTTP request. The built-in webserver of Ozeki NG SMS Gateway will accept the request and will send the SMS message containing the one time password through a GSM modem attached to the computer with a data cable. (If an Internet SMS service provider account is configured in Ozeki NG SMS Gateway, it can also send the message over the Internet).

Please note that it is more secure to send the one time passwords using a GSM modem through the airwaves to the recipient, than through an Internet based SMS service provider account, because it is significantly harder to intercept an SMS message traveling through the air, than it is to intercept internet traffic.
