The uncluttered domain of encryption may now be toppled by the influx of quantum systems. In the summon leading to the dismissal of ten Russian spies from the United States, the FBI clearly stated that it gained access to the encrypted communications after sneakily entering into the spies’ home, where the agents found information with a password of 27-character.
Also, the FBI found out to be more productive for burglarizing the house along with cracking the 216-bit code, despite the computational resource of the government behind it. That is due to the modern cryptography, when used suitably, can be very strong. Do you know that cracking an encrypted message requires an investment of an incredibly long span of time?
The encryption algorithms used in today’s generation can be easily broken. The security is derived from the crazy impractical length of time it take for the processing.
For example, you are using 128-bit AES cipher. The possible number of keys with 128 bits is 3.4×1038, or 2 raised to the power of 128, or 340 undecillion. Assume no data on the key is available, an attempt to break the code would lead to testing each and every possible key until the one that actually works.
Supposing that there is enough computing power amassed to test the trillion keys every second, test all the possible keys would approximately take around 10.79 quintillion years. This is for the 785 million times the period of visible universe, i.e.13.75 billion years. Alternatively, there are chances that the user can lucky right in the first ten minutes.
This is the current scenario. But in the upcoming future, cracking the keys and codes can be quite trivial, due to the concept of quantum computing.
But, before we understand more about the theories of quantum computing, we first need to know more about data encryption.
There are basically two types of data encryption algorithms used primarily in an enterprise-level secure communication: symmetric and asymmetric.
Symmetric algorithm is typically for sharing the actual data, whereas asymmetric algorithm is used for sharing the information along with the keys.
Symmetric encryption necessitates the sender and the receiver both for using the same algorithm and encryption key. Decryption is simple procedure of reversing the encryption process — hence having this symmetric label.
There are various symmetric algorithms, but the most popular one which most of the companies use is called the AES, i.e. Advanced Encryption Standard, published in the year 2001 by the National Institute of Standards and Technology after 5 long years of testing. It substituted the DES, (Data Encryption Standard) that debuted in the year1976 using the 56-bit key.
Honestly speaking, code-breaking in today’s era is end-run game – which is all about grasping the user’s system. Nowadays, anything pulled out from the air, you cannot decrypt it, if there is end-to end encryption.
But one of the biggest challenge with the encryption is to make sure that it is actually being used in the right circumstances.
All of the business-critical information need to be encrypted both at rest and in transition, especially the details of your bank account. All the banking Industry and Security Standards Council need to encrypt the data right at the user’s end – along with not saving the private data at all. Even any data-breach notification law do not asks you to disclose the lost data if it was previously encrypted.
You must be wondering about what option you need to enforce for Strong Encrypted Messaging App Technology in the Clock Ticking in Race, as 2020 Looms – The answer is Signal. This option is worthwhile as other apps that have already adopted the Signal’s protocol for the high quality encryption it provides for all the conversations.
The important thing to keep in mind is that the enterprises need to switch applications, right from Facebook and Google that are only interested in the collection of information about selling the ads.
Signal clearly is a winner amongst the different options when it comes to data security. There may not be different fancy features but in this world of continuous surveillance, Signal offers an important service that protects it all.
