CellTrust SecureSMS™

CellTrust takes SMS to the next level

While the use of SMS or “text messaging” is starting to take off and serve all types of industries and marketing requirements, there are still three important obstacles sometimes preventing the use of SMS for commercial marketing and messaging:

1. No one, not even carriers, guarantee delivery of text messages so you can never truly know if messages have arrived or been read by the recipient.
2. As of today, there are ways to read message content as it is being transmitted through the networks and Internet before it arrives on the end user's mobile phone.
3. Once a message has arrived on the cell phone, anyone who happens to pick up the mobile phone has the ability to read it.

The above challenges have been considered weaknesses particularly for verticals such as financial services, healthcare and any mission critical program such as emergency alerts.

That was then, this is now.

Taking SMS to the next level, CellTrust continues to tackle mobile security challenges one obstacle at a time by proudly offering its CellTrust SecureSMS Module, giving businesses greater control of text message delivery and receipt.

How does it work?

CellTrust customers already using the SMS Gateway can easily take advantage of the added security that comes with the CellTrust SecureSMS Module by adding the (Secure) parameter to the API communication. Once the parameter has been added, CellTrust can manage and exchange all customer messages via the highly secure Advanced Encryption Standard (AES) protocol.


To achieve full CellTrust SecureSMS Module functionality, a small micro-client application is automatically installed on the cell phone of the end user. CellTrust’s patent-pending micro-client technology is the impetus for the CellTrust SecureSMS Module allowing you to send and receive communication to and from your target audiences via the mobile phone with unprecedented reliability.

An additional advantage of using CellTrust SecureSMS is the possibility to distribute lengthy messages resulting in a much more convenient user experience. Rather than being bombarded with numerous SMS messages which currently have a 140 character limitation, they receive one message.

The CellTrust SecureSMS Module manages and exchanges messages via CellTrust’s highly secure platform and infrastructure, giving businesses the ability to:

• Use the same set of APIs to send both secure and normal SMS or “text messages”;
• Confirm that the mobile device is able to receive secure SMS messages;
• Easily market and push the SecureSMS micro-client to their customers’ mobile phones so they can receive and send secure text messages instantly;
• Confirm text message recipients have received their SMS messages;
• Notify the sender when the recipient has opened to read the message;
• Definitively measure ROI of mobile programs and their effectiveness;
• Increase market intelligence and strengthen the customer relationship through a trusted exchange.

In contrast to mono-key encryption methods, CellTrust SecureSMS utilizes a unique-key solution whereby each mobile phone has a unique encryption key. Keys are dynamically generated, continuously changed and never kept on the mobile phone itself.
