End-to-End Encryption Online: Benefits & Freedoms
The use of end-to-end encryption (E2EE) has increased in recent years, making it more difficult for anyone but the sender and recipient to read or understand messages.
People want to communicate without having their messages read or intercepted by third parties. One significant reason is that users fear their discussions via popular apps being exploited for unknown purposes. Monetization of their correspondence is one of the triggers. If some users still use certain messaging apps, unknown entities could secretly read their messages.
So, let's examine the need for end-to-end encryption and how it fits into our digital world.
What Is End-to-End Encryption (E2EE)?
End-to-end encryption is a secure communication method that protects data from being accessed or intercepted by unauthorized parties. At the same time, it is transferred from one end system or device to another, exchanging data between only the intended recipients who can decrypt the information. This includes data like text messages, photos, videos, and location.
Even if data is intercepted during transmission or stored by third parties, it remains encrypted and unreadable to anyone without the decryption key. Only the intended sender and recipient can access and read it.
End-to-end encryption is commonly used in messaging applications and other communication platforms, such as WhatsApp, Telegram, and Zoom, to ensure the privacy and security of user data. It prevents third parties, including messaging service providers, from accessing the content of the messages or other sensitive information.
It is a vital tool for online security, as it protects communications from being intercepted by third parties. These third parties include the network provider, application developers, or government agencies. If anyone were to try and read the messages without going through the proper channels, they would only encounter unintelligent numbers or letters. Thus, end-to-end encryption is very safe in conjunction with other parts of cybersecurity.
What Are The Advantages & Disadvantages of End-to-End Encryption?
Notable advantages of E2EE include:
Privacy of data
As discussed above, sensitive information like location, important timestamps, or bank details remains hidden from the third party. You can freely exchange multimedia files without the fear of prying eyes. Adding to the security it provides, E2EE has two levels of protection.
Protection at the device level
Other forms of encryption methods secure your data strictly at the server level. Only using this level creates a gap for cybercriminals can exploit through the server. However, end-to-end encryption ensures that only the intended recipient of messages or other data can decrypt them. Decoding information is much more complex at the device level, and thus many hackers refrain from peeping into such applications.
Messages remain the same
Another significant advantage of E2EE is that no one can change the information exchanged between the sender and the receiver. It ensures that even if anyone tries to change any part of the text, the entire message becomes nonsensical on decryption. The garbled message will indicate a security breach to the receiver.
What Are the Disadvantages of E2EE?
Even though E2EE is a superior technology, there are a few disadvantages:
You are not entirely hidden
Yes, E2EE hides the information exchange between the users, but third parties still know that data is being exchanged between users. They can deduce some information based on the timings of your message exchanges. Also, not all services supporting end-to-end encryption include metadata protection.
No physical protection
E2EE is only safe if your device is safe. If any device gets stolen, everything exchanged between the user becomes available to that person.
There is still leverage
Some companies still store details about your communications and information about the data exchanged. This information is further used to index individuals' usage, connections, and frequency of data exchange.
The dangers of privacy
There is a lot of debate about whether E2EE will be used as intended. It is incredibly beneficial to users. However, entities fear that criminals and other vicious people can exploit this enhanced privacy. Government institutions can block access to apps supporting end-to-end encrypted conversations in other cases. Such blocks can prevent the free flow of information and collaborations outside government-tracked apps.
What Else Can You Do to Secure Your Digital Communications?
You will need more than just E2EE to secure your devices and online communications. But not to worry, these methods are still within most companies’ ability to implement.
Use a VPN
A VPN (Virtual Private Network) will keep your messages encrypted and hide your internet identity. It encrypts your internet traffic and disguises the IP address when accessing the web. This helps keep cybercriminals from stealing your identity and ensures that they can't see what kind of content you like to visit while surfing online.
Thus, a VPN download can benefit anyone looking to safeguard Internet activity from data brokers, advertisers, and government institutions.
Use strong passwords and multi-factor authentication
Even if your device lands in the wrong hands, a strong password will keep the person out of the application. Adding multi-factor authentication (MFA) will further amp up your security.
Implement antivirus & cloud email security solutions
While you use a secure network, malware can still attack your system if you visit an unsafe site or download from the wrong source. For this reason, always keep antivirus installed and updated on all your devices.
Also, it is essential that businesses implement a comprehensive cloud email security solution to detect and block all email-borne threats before they reach the inbox.
