Technical data


The minimum level of security is always important. Normally it is scored as an equivalent of the symmetric encryption bits.

And it is not equal to the bits your algorithms are using. It is the least secure point in your solution.

It is а standard that voice is encrypted with AES 256. Unless the special attack is used (see below) the attacker will not attack it. Attacker first will try to get the key. One way is to get it during the key exchange.

Here is the table with minimum level of security depends on the key exchange algorithms used. We have taken it from the NIST Recommendations.

At our solution we implement ECC 571 and/or DH 16 384* key exchange which is even above the requirements. *Some customers ask to implement DH 8192 because of the certification reasons.

 

9+ layers of security

Multiple locks are normally better than one, especially if you can loose the key. Our system is designed for virtually unlimited multi layer implementation. So number of layers can be changed per request. In the fully implemented platform there are 9 (!) layers of security:

  • 3 key exchange channels (either independent or 2 of them can have completely different algorithms and 3rd is a mix from 2 channels)
  • 3 cascade symmetric encryption
  • 1 HSM module authentication (if device have SD slot for SD-HSM)
  • 1 device watermark authentication
  • 2 additional “can be modified by customer” algorithms

Some of these layers could be implemented by the customer if required by the project.

 

Works on modern mobiles

SV works on all modern iOS and Android devices from the box. Other platforms are added easily on request.

svdevices

Standard platforms:

  • iOS 9.x, 8.x, 7.x
  • Android 6.x, Android 5.1.x, 5.x, 4.4 @ .x, 4.3.x, 4.2.x
  • SV Deskphone

 

Desk-phone version is available

svdeskphone

You can have SecureVoice IP Deskphone staying on your table fully compatible with mobile software.

 

More platforms on request

SV designed with multi platform approach in mind. As a results platforms can be introduced fast by adding platform specific UI/UX.

Here are platform list where SV core already works:

  • Windows 10, 8.x, 7
  • Mac OS
  • Linux
  • Blackberry 10
  • Windows Phone 8.x

 

Management Panel

Management of customers, groups, users and configuration settings

 

World top class audio engine

Meet the results of 9+ years of selection and competition between audio engines.

In the result is works best in both mobile worlds: one with LTE, 3G and the one with older networks.

Codecs are dynamically changing and you will have HD sound with the high bandwidth on LTE, while software will automatically reduce the usage in the 2G networks up to the tiny 4.75Kbit codec.

 

Works good in both modern and old mobile networks

Years of trials in more than 50 countries result in the software that are quite tolerate to the changing network condition.

As a result software is working in 4G, 3.5G, 3G, 2.75G, 2.5G and 2G networks

Here are the list of networks we have optimized it for:

  • LTE, TD-LTE,  LTE Advanced
  • IEEE 802.11 (WiFi): 802.11b, 802.11b/g, 802.11n
  • HSDPA+, HSDPA
  • UMTS, UMTS-TDD
  • HSPA, HSPA+
  • CDMA EV-DO (Rel. 0, Rev.A, Rev.B)
  • EDGE, Evolved EDGE

 

Permissions to call and see who is online

Assigned administrator can divide persons in groups and arrange who is able to see/dial/chat with each other. In this way you can isolate e.g. top members from regular staff, while still allow e.g. department head to connect to the head of the division.

 

Closed Group usage (Corporate Address Book)

Secure Voice support closed groups. For the closed group of people or agency it make sense that no one else can dial in. This can be done either permission based or even for highest level of confidence by modifying encryption algorithms especially for the particular agency.

 

Encrypted voice calls, point-to-point

Governmental encrypted calls in one click. The encrypted voice are sent from device to device in the shortest route possible.

 

New ephemeral keys for each voice call

For each call new random ephemeral keys are generated and destroyed after the call.

For longer calls there is an customization option to change ephemeral keys during the call.

 

Encrypted Instant Messaging

Instant Messaging with full governmental encryption and fast message propagation.

svmessage

Users are divided in groups.

 

Encrypted Group Chats for 500 users in one chat

Governmental encryption for up to 500 users right from the box.

In the available customized version this can be extended to 1000 or more.

 

Encrypted Push-to-Talk for Large Groups

You can have hundreds of people listening on the channel to the command.

 

Encrypted File Transfer

Files are transmitted point-to-point encrypted with the same governmental security level.

 

Works in completely isolated network

Secure Voice is designed to work in isolated environment.

Some tested examples:

  • Corporate Intranet
  • On a ship
  • In the desert
  • MPLS network
  • VPN

 

Works internationally and in multi-country set up

SV works internationally from the box. You can install SV server in your country and go thousands kilometers away and still would have a good conversation quality.

Additionally  there is a way to have shortest possible time for countries interconnect even if direct traffic between phones are blocked.

SV regional servers can be deployed to support large aboard units

 

Can work without Push for the maximum security

Most software on the market will use Apple’s or Google’s push messages. This theoretically have no impact on the security, but practically gives out some (even very small) info about the call made between devices.

SV can be configured to work without using any 3rd party push services to save every single bit of security.

 

Can work with Push to extend battery life

If you use standard software on your devices than Push is already in use.

In this way it may be reasonable to enable Push usage to extend battery life.

Coming soon

Secure Voice is constantly evolving. And you can be driver as soon as you submit the request.

However here are short list from our timeline. These features are already “tested in lab”.

Means you can have them fast if needed

  • Encrypted Conference Calls
  • Encrypted Video Calls
  • Secure Double Telepresence Robot
  • NFC as additional authentication factor

 

Absolutely No Backdoor

The Secure Voice is made with absolutely no backdoor and comes with a number of possibility to checks this.

Just a few basic points:

  • As a customer you can come for the complete source code review
  • As a customer you can “build your own server” from the source code
  • In deeply customized version you can own the source code (on the non exclusive bases of course)
  • You can (and our customers always do) perform all blackbox testing of the software
  • You always can have own server at your own premises
  • The software can be 100% isolated from Internet and public networks if needed

In order for you to choose which method is appropriate for you to protect your phone conversations and SMS we offer free security advice.

Choosing the right solution depends on many parameters:

  • which channels of communication are being used
  • how many offices will be using such a system
  • number of users of the encryption network

In some situations a complex multi leveled system has to be used in others a simple solution is sufficient.

We will let you know what type of protection suits you best based on our experience.
