PrivateWave Quick Start Guide for iPhone

This guide provides you easy step-by-step instructions to help you get started with  PrivateWave .

Secure calls with  PrivateWave

Calling with  PrivateWave is a very easy task. You can both use your contact list or directly dial a number using the dialpad.

To make a secure call, you and the called party must have PrivateWave software running on the mobile device, be connected to the Internet and to the same PrivateServer .

Calling by Contacts list

Select Contacts tab from the tab bar, tap on the contact you want to call and select the contact number associated with  PrivateWave .

figure 2. your address book is shared

As you can see in figure 2. your address book is shared each contact can show a coloured ball at its left, or nothing at all. These are status marker and they represent the Presence Status for each contact.

Presence

The Presence avoid users to call contacts who are not reachable, eg: because they do not have  PrivateWave  activated and/or connected. The main value of this feature is to improve user experience suggesting the possible outcome of a call.

Contacts lists

PrivateWave  gives you access to three different kind of lists:

• ALL: it lists all the contacts which are in the mobile address book, ordering them in the very same way.
• KNOWN: it shows only known contacts (registered or not) according to  PrivateServer 's knowledge. This means it is a list of the contacts that are recognised by the server and thus can have a status.
• FAVOURITES: it reads the contacts marked by you as " PrivateWave  favorites". It's a selection of contacts you choose to have apart, in order to make speed calls.

Each list may show a Contact status beside each contact. The contact status legenda is shown below:

Contact status

	Online	The contact is reachable. You can make a secure call to the user.
	Offline	The contact is not reachable, because is not under network coverage or is offline. You can try to make a secure call but the call will likely fail
	Error	There is a comunication error between your phone and the server. The contact status is unknown, anyway you can try to make a secure call

Calling by dialpad

You can make a secure call to any arbitrary number (presuming that the call peer has  PrivateWave  connected) from  PrivateWave  menu by simply entering the number with the on-screen keypad and pressing the dial (green) button.

Receiving a secure call with  PrivateWave

Once  PrivateWave  is installed and all the settings are correctly configured on your device you are able to receive a secure call. When a secure call arrives to your device a notification bar will be shown on the top of the screen. Tap on the notification to bring the application in foreground, then answer or decline the call from the application. After the system have exchanged and verified the security keys the you can start the conversation.

Checking your security

A  PrivateWave  phone call is always encrypted. To check that nobody is intercepting the call, you must verify the security verification words with you remote party. After the call has been connected  PrivateWave  displays the same two security verification words on the screen to both parties. If both of you and your contact see the same security verification words then the call is secure. The security verification words are different each time you make or receive a secure call. If the words are not the same hang up the call immediately as this may be a sign of a security attack..

Call status

To establish a call  PrivateWave  completes three phases shown by three icons:

Call status icons

	Red light	Starting the connection	Connection not yet established. This step may take several seconds
	Yellow light	Key exchange	Connection established: encryption keys are being exchanged.
	Green light	Secure call established	Connection established and secure. You can now speak securely

Inviting your contacts

Using your address book you can invite your contacts to join  PrivateWave . Tap on more button in the bottom right corner and select invite others choose the contact that you want to invite. The application will create a text message and after your confirmation will send it to the selected phone number. The receiver will only have to open the link contained in the SMS to install and use  PrivateWave .

History

Every event performed or received on your  PrivateWave  is listed into the "History" tab, which can be displayed by pressing "Recent" icon on the tab bar.

Each event has a detail icon (the blue circle around "i" character).

figure 8. event detail

By clicking on this icon you have access to event's details (cfr figure 8. event detail). 

Secure Messages

You can communicate with your peers by text messages using the Secure Messages System which provides Secure Messages. A Secure Message is a text message that travels into the same encrypted architecture of the Secure Call. 

• If  PrivateWave  is configured with PIN disabled each Secure Message has a time validity, after which it expires. Expiration means that the Secure Message content is no longer readable and it's gone for good. Instead of message content you'd rather read "Message received" or "Message sent".
• if  PrivateWave  is configured with PIN enabled each Secure Message is persistent.
