Have you heard about the term E2EE? Many of us say “NO” but I am telling that your day is start and end with this one did you believe it? Yes in this smartphone era the term End to End Encryption (E2EE) plays a vital role in our daily life. But after hear this statement you’re all think that how is it used in my life? Without even I aware of it. But we’re all using it without aware of it. All of you use the messaging apps like Whatsapp, facebook messenger, etc right at least you’re all used an internet banking even once in your lifetime then you’re using this concept. After hear this statement one thing will come to your mind right you can seen the word “End to End Encryption” in Whatsapp while you’re chatting with someone for the first time. Ok I can see it? But how it used and what is the advantage of using it? Now these question are running in your mind right. Here we explore the solution for those questions. So as per our blog regulation, we have to see the definition, example, working process, advantage and the limitations of E2EE. No more further discussion let’s move on to the topic.
Apart from the technical definition, here I give you a real
life example for better understanding. If you want to transfer some amount to
your friend’s account but today is bank holiday, then you choose the internet
banking option but you’re fear for the fraudulent activities over internet. But
through this E2EE technology your bank details are concealed and it can’t be
read by the third parties which means your details as secured as it was in
locker. I think now you can understand why it plays an important role in our
daily life. Using the following technical definition will give a better
understanding of this concept.
“End to End Encryption (E2EE) is a method of secure
communication that prevents third parties from accessing data while it’s transferred
from one end system or device to another”
Through the real life example and the technical definition
all of you understand what E2EE is. Now I habit to explain the working process of
this technology.
In E2EE, the data is encrypted on the sender’s system or
device and only the indented receiver can decrypt it. As it travels to its
destination, the message cannot be read or tempered with by an intermediaries
like Internet Service Provider (ISP), Application Service Provider (ASP),
hacker or other entities. But how this encryption and decryption process is
done? All these process are done through cryptographic keys. This one uses the
public key encryption method. In this method, there are two cryptographic keys
used for encryption they use public key and only the corresponding owner of
that public key, has a private key for decryption. So without those keys you
can’t see what’s the message is. The intermediaries only seen the text that can’t
read by them which means the process of eavesdropping of the content is
impossible one. Through this working process it is clear right now we have to
reveal the places that use this technology.
End to End Encryption is used when data security is
necessary, including in the finance, healthcare and communications industries. It
is often used to help the companies comply with data privacy and security
regulations and laws. Now it’s a time for us to discuss about the advantages
and limitation of E2EE.
The major advantages of E2EE are listed as follows:
- Security – this is the main aspect of using E2EE technology.
- Tamper Proof – the encrypted message is only decrypted by the appropriate user incase if the hacker altered the message in middle, then it’s impossible for the receiver to decrypted which means the spam content can’t be accepted by the device.
- Compliance – helps in many industries to make their data as a secured one.
Now the limitation of E2EE is..
Hey Wait! What limitations? E2EE is provides lots of
advantage then how it has limitation to answer this question, it’s must to use
one proverb (after long time)
“No one is perfect”
According to this one, the limitations of E2EE are listed here:
- Distinguish the end point is must if it is not done properly, then the message will delivered to the wrong person.
- It provides too much security so the third parties done illegal activities but identify them is very difficult.
- Only the message itself was encrypted but metadata (contains recipients information, sender information) can’t be encrypted
- It is a strong technology now but we can’t guaranteed it for future.
I think now you’re all understand what the E2EE technology
and how to use it. Thank you for reading!!
