Encrypted Calls from Your Smartphone
Make encrypted calls using the usual dialer on your cell phone, it is possible. Today we want you to know the native application of Wings Mobile as Secure Call is.
It is a native service that offers communication protection, adding to the list of applications for cell phone security offered by Wings Mobile.
But before explaining more about this tool, it is important that you know some terms about encryption in calls, how they work and where you find these possibilities.
What is encryption in communications about?
You may have seen on more than one occasion that some applications use end-to-end encryption to provide greater protection and confidentiality in calls and chats.
What does this ensure? That no third party can access the communications. This is possible thanks to encryption protocols that hide the information or content that is transmitted, in this way, only those involved in the conversation can hear what is being said.
All this happens over the Internet network, which is why a stable connection is essential for its correct operation.
Everything you need to know about encrypted calls
As we mentioned, what these types of applications do is hide the information that is transmitted and this is achieved thanks to codes that protect the data.
It is as if the voice traveled through channels that hide it and only when it reaches the other side is it possible to reproduce it. And if a third party tries to access the call, they will first have to crack the code to access what is being spoken.
The protocols for encrypted calls prevent their interceptions or spying, and Secure Call is a fairly robust option, as it is part of the mobile security applications provided by Wings Mobile.
Secure Call for more telephone privacy settings
This native service has a triple security level made up of: TLS (Transport Layer Security), ZRTP (Zimmermann real-time transport protocol) and ICE technology for P2P. Calm down! We are going to explain each one to you.
All these systems together assure the user that no VoIP data flow passes through a server, as it reaches the receiver directly. And furthermore, its privacy settings ensure that even Wings Mobile cannot hear your calls.
The novelty of this application is that it is exclusive, so you will not see this functionality in any telecommunications company in the market. And although you can find some alternatives in tools within the marketplaces, none is as secure as Secure Call.
What are your three levels of security?
Why is this service so complete? As we mentioned, it includes three levels of security, we are going to explain each one to clarify all the doubts that may arise:
TLS
Transport Layer Security, which translates security into the transport layer, is the first level offered in this encrypted call service. It is a cryptographic protocol that provides a privacy setting in communications that travel over the Internet.
This is the improved version of the SSL certificate and it encrypts the information using two additional protocols: authentication (TLS Record Protocol) and mutual agreement (TLS Handshake Protocol)
- Record or authentication: it is in charge of verifying the connections and making sure that the data transmission is done through a reliable and private network.
- Handshake or by mutual agreement: encrypts and packages the information assigning an authentication code that can only be deciphered by the parties involved.
In summary, the TLS protocol transports voice data through a verified and secure channel, during the process, it encrypts the information so that it is only audible by users who participate in the conversation, whose phones are the only ones that can authenticate the cryptographic keys .
ZRTP
Zimmermann real-time transport protocol, the man-in-the-middle protocol, provides greater security to communication points, how? Since there are multiple ways in which criminals can access your information, the function of this tool is to prevent it to the max.
Its name is given because it prevents the terminals from being intercepted by a third party that can retransmit or alter the sending of voice data during a call, this is achieved by using temporary keys.
This protocol does not make use of the signaling flow for the exchange of keys, but rather lowers the media flow to make interception attempts more difficult.
What is your algorithm?
The algorithm that uses this protocol is the Diffie-Hellman, which offers multiple advantages. Among them, certificate management and key management will no longer be necessary, since these are temporary and are discarded as soon as the call ends.
This, added to the use of short authentication chains called SAS, make encrypted calls a secure option. Because SAS generates more than 65,000 different values so that attackers cannot decipher the communication key during the duration of the conversation, protecting the ends against any possible attack.
ICE technology for P2P
The ICE, which translates to Establishment of Internet Connectivity, is a fundamental technology in P2P systems for them to function properly. Let’s go in parts:
P2P is an open Internet system by which multiple content is shared, whether voice or image, and is used in VoIP communications to create anonymous routing.
With the foregoing, it could be said that ICE technology for P2P allows Internet connections to be more fluid, without affecting the security and privacy systems that protect encrypted calls.
Secure Call, the best option in encrypted calls
Now that you fully know their security levels, we know that you are going to want to join this communications revolution. Do you wonder how the app works on the phone?
Since it is part of the applications for cell phone security, offered by Wings Mobile, you can only access it if you have a device from the brand. Well, these already have the secure call option incorporated into the dialer.
You just have to access the keyboard or contacts and tap on the call icon with padlock. With this revolutionary tool you will make sure that nobody accesses your communications.
We hope you get excited and start enjoying all the technological advantages of smartphones with native Wings Mobile services. Write us in the comments if you know about this alternative or if you use apps with a different encryption system.
