Chapter 8. Using SSL for HTTP

This chapter explains how you can use SSL to ensure secure HTTP communication on both, client and server side.

Beware that the gateway, is acting in both roles of the HTTP model:

1.as HTTP client, i.e. for requesting URLs while acting as WAP gateway and while fetching information for the SMS services.

2.as HTTP server, i.e. for the administration HTTP interface, the PPG and for the sendsms HTTP interface.

That is why you can specify seperate certification files within the core group to be used for the HTTP sides.

You can use one or both sides of the SSL support. There is no mandatory to use both if only one is desired.

Using SSL client support

To use the client support please use the following configuration directive within the core group

group = core

...

ssl-client-certkey-file = "filename"

Now you are able to use https:// scheme URLs within your WML decks and SMS services.

Using SSL server support for the administration HTTP interface

To use the SSL-enabled HTTP server please use the following configuration directive within the core group

group = core

...

admin-port-ssl = true

...

ssl-server-cert-file = "filename" ssl-server-key-file = "filenane"

WAP and SMS gateway specifications

Nokia has long been a pivotal player in the telecommunications industry, and its contributions to mobile communication technology are numerous. Among these contributions, the Nokia WAP and SMS Gateway stand out as essential elements in enabling mobile internet access and messaging services in the early days of wireless communication.

The Nokia WAP (Wireless Application Protocol) gateway was introduced to facilitate mobile access to the internet and to allow users to interact with web services through their mobile devices. Built on a client-server architecture, the WAP gateway acted as a bridge between the mobile network and the internet, translating traditional web content into a format that mobile devices could effectively render. This conversion was crucial, given the limitations of early mobile devices regarding screen size, processing power, and network bandwidth.

One of the main features of the Nokia WAP gateway was its ability to provide users with real-time access to information such as weather updates, news, and stock prices. By using a lightweight markup language called WML (Wireless Markup Language), the gateway allowed developers to create mobile-friendly websites that could be accessed via WAP-enabled devices. This marked a significant step toward the mobile internet we know today, creating a new realm of possibilities for developers and users alike.

Another critical aspect of Nokia's offering was the SMS (Short Message Service) gateway. The SMS gateway provided a robust platform for sending and receiving text messages across various mobile networks. It enabled seamless communication between devices, regardless of the underlying technology. This feature made SMS a popular choice for both personal communication and business applications, such as marketing campaigns and customer service notifications.

The Nokia SMS gateway utilized established protocols, such as SMPP (Short Message Peer-to-Peer), to ensure reliable message delivery and efficient interaction between SMS applications and mobile networks. Its characteristics included scalability, allowing service providers to handle large volumes of messages, and flexibility to integrate with existing applications and systems.

In summary, the Nokia WAP and SMS gateway played a vital role in the evolution of mobile communication. With features that enabled mobile internet access and streamlined messaging capabilities, these technologies laid the groundwork for the mobile-centric world we live in today. Their legacy continues to influence mobile application development and the broader telecommunications landscape. As the industry progresses, the innovations introduced by Nokia serve as a reminder of the foundational technologies that paved the way for modern mobile experiences.
