## What is Trust4Mobile Enterprise?

***IMPORTANT NOTICE: This application requires a valid digital certificate issued by certSIGN. To get one, visit our website: www.trust4mobile.ro***

Trust4Mobile Enterprise is an easy to use mobile application that ensures the privacy of every call, text message and document you either initiate, send or receive, or voice conference you attend, using your mobile device.
With Trust4Mobile Enterprise, your sensitive information is encrypted end-to-end, in real time. This means all your information is protected 100% of the time, both in transit and at rest (while stored on your mobile device). Trust4Mobile Enterprise makes this possible by using a mix of digital certificates that rely on strong cryptographic elements and military-grade encryption technologies. 
Trust4Mobile Enterprise combines simplicity of use through an exceptional user interface with high standards of security technologies, initiating encrypted phone calls or attending voice conferences just as simple as making a standard phone call through its friendly user interface.

With Trust4Mobile Enterprise, your privacy always comes first by giving you full control over its functionalities and security features. You are able to decide whether the application saves the call history or not, if it stores (in encrypted format) the messages and documents you receive or the lifetime for a message stored locally. Additionally, you can create and manage your own encrypted conference sessions.
TECHNICAL INFORMATION
For each message or call, an individual key exchange session is generated. All keys are self-destructed when the call ends and cannot be reused. The messages are stored locally in encrypted format even after they have been read.
Trust4Mobile Enterprise uses cryptographic keys and digital certificates in a PKCS#12 container, stored in the memory of the device. The protection of the keys and the digital certificate is assured by using a chosen PIN code that protects the access to your private key.
This allows the implementation of the two-factor authentication mechanism when the digital certificate stored on the mobile device is used: 
•	What the user has: the digital certificate stored on the mobile device (locally stored or on the secure element), 
•	What the user knows: the password or the PIN code that authorizes the access to the private key associated with the digital certificate.
•	Supported features, standards and algorithms:
•	PKCS#12, SSL, TLS, x509v3.
•	AES encryption with 256-bit keys, RSA 2048-bit keys, SHA256 algorithm.
