Here it comes - multimedia messenger. Chat, make voice, video and conference calls.
We implemented most recent achievements and cutting-edge technologies in IT security to develop cryptographic protection mechanisms in our messenger. The level of encryption and its performance meets the most stringent banking standards.
Your private and business information is totally safe and confidential when using our messenger. SafeUM eliminates any possibility of data interception and spoofing and also provides the parties' authentication.
Here's more information on the technology, cryptographic systems, and some functionality and features:
>> Encryption. The information is encrypted by subscriber A, stored on the server and transmitted in encrypted form. After going through communication channels it is decrypted by subscriber B. The information is open only at the end nodes - where it is encrypted – users' mobile phones or tablets. Other pieces of equipment such as servers, switches, routers, and SafeUM servers contain only encrypted information.
>> Digital signature - authenticates the parties and ensures data integrity. Account and chat hacking, as well as spoofing, are totally eliminated.
>> Hybrid encryption scheme. The asymmetric block encryption algorithm is used to increase encryption performance. To transfer the encryption key in the data exchange process asymmetric elliptic curve cryptography is used. It has a high level of cryptographic security with a relatively small key length. This hybrid scheme allows us to "take the best" out of each system and combine into one cryptosystem with very good encryption performance and cryptographic security.
>> The ElGamal scheme is used for symmetric key transport. SafeUM cryptography experts implemented complex algorithmic optimization of the encryption process taking into account the stringent requirements of the banking sector. The application works fast and ensures high-quality communication without any delays. In other words - the communication quality is equal to that of the other messengers and, at the same time, provides a very high level of security and extremely fast encryption performance.
>> Our servers have no hard drives. We use Redis in-memory database - the best option for SafeUM that allows storing all (!) the data in RAM. Third parties can only request these data after going through a complicated legal and bureaucratic procedures. And even then, SafeUM can disclose data only in the encrypted format, hence we don't have it in another form. Only you have the private keys which are stored on your device's RAM. The keys are generated on the basis of the passphrase that you must remember. We, the provider, cannot decrypt messages stored on the server.
>> Some of SafeUM multimedia messenger's functionality:
- You can simultaneously use up to three accounts online in one messenger.
- No phone number is needed to sign up(in case of registering with the login-password scheme).
- You can disable chat history saving.
- SafeUM uses a system of three security PIN-codes: the first is used to sing in with complete functionality, the second - to sing with secret contacts and chats hidden, and the third one - to deactivate the account.
