End-to-End Encryption: Pros, Cons and Alternatives

21 min read

As the world becomes more digitized, the role of secure online communication tremendously rises. Collaboration platforms play a part of mediators between companies and their workers, families, and relatives, friends, fellows, etc. Thereby, it’s not a surprise that privacy and anonymity are becoming essential collaboration software traits when it comes to a question: Which software should I use? It happens due to the sharp increase of cybercrime cases, hacking attempts, and data leakages, which have caused a lot of questions such as “How private information could be protected?” or “Which messaging platforms are the most secure?”.

One of the most prevalent cybersecurity systems is end-to-end encryption. It is a data encryption method, which takes place on a device level and encrypts intel so that only sender and recipient could read it. A device generates unique keys both for private and public messaging. “Private” keys decrypt incoming messages while “public” keys are shared with the senders, allowing them to send an encrypted message. End-to-end encryption is recognized as a benchmark of information security and excludes the possibility that third parties or hackers could read data.

Pros of End-to-End Encryption

1. Full Privacy

The first and the most important advantage of E2EE is that nobody except the recipient can read the sent data. It is not a secret that corporations that provide communication and data exchange services try to collect as much information about the users as possible, using it later for commercial purposes.

Such information isn’t properly protected and is stored decrypted on multiple corporate servers so that it can be stolen or seen by any third party or attacker. End-to-end encryption provides total privacy and the integrity of the transmitted data because only you and your interlocutor have keys to “unlock” the data and see what’s inside. Those keys are stored on the devices and are unique for each user.

2. Full Integrity

Even the government, police, or big corporation can’t read your messages. From one side, such a robust protection method could make some “bad” information unreachable for law enforcement agencies and governments, but from the other side, it ensures information integrity. People want to keep their intelligence untouched and integral that could be provided only by full privacy and encryption protocol, that cannot be circumvented.

3. Saving the Data from Hacking

A presence of private and public keys means that no one can “read” the information in a message. Only keyholders are able to decrypt it and reveal the content. Additionally, users’ data isn’t stored on servers, so the risk that it could be exposed significantly reduces.

That makes people feel like they still have the right to live a private life, despite uncountable hacking attempts, breaches, and corporate spying.

The Reverse Side of End-to-End Encryption

As it was mentioned above, even governments and security forces can’t get access to the end-to-end encrypted intel. That gives the possibility to create entire criminal communities where villains share restricted information.

Many governments have already requested to limit the usage of E2EE or at least give them a way to access the needed information. But still, big “spaces” of the Internet remain closed for anyone, except the users. Different parties or individuals could misuse the E2EE protection.

Besides, E2EE doesn’t protect devices themselves. If an attacker gets access to it, it won’t stop him from exploiting and misusing the user’s intelligence. Even a usual, widespread malware can make a total mess and create severe negative consequences. Plus, the user can’t be sure of how properly his interlocutor’s device is protected.

Possible Alternatives

Another efficient method is encryption-in-transit. The technique lies in the data enciphering through all transfer stages: from the user’s device to the server, then to the recipient’s device. While entering or exiting each of these stages, information is being enciphered and deciphered.

Servers’ owners could use, view, or save temporary information, which has nothing to do with privacy or confidentiality. Additionally, intelligence agencies, law enforcement parties, or other authorities can force software providers to reveal hidden intel by addressing them with a national security letter or a warrant.

dSTAR iCommunicator: A Perfect Example of A Highly-Protected EE2E Collaboration Platform.

dSTAR Lab goal is to create and provide a private, protected, and safe environment where people could freely communicate without the fear that their very action could be exploited or shared with third parties.

End-to-end encryption is the basis on which dSTAR was built. It ensures an extremely high security level along with other unique features such as disappearing pass- and bio-hidden messages, decentralized infrastructure that makes a hacking attack impossible, verification with safety numbers, and others. Such a structure reassures complete privacy and integrity.

dSTAR iCommunicator provides safe and seamless communication in which everyone can participate to insulate themselves from eavesdropping, personal data leakages, and other nuances of the modern digitalized world.
