Everybody
wants to ensure the security and privacy of personal data on mobile phones or
computers. In today’s world, there is an increased importance for Cryptology,
that is, the art of keeping information secret.
In the
digital world, there is one thing that is of utmost importance; and that is data.
We use passwords in order to secure our data but hackers often manage to steal
and misuse it. So in the domain of information technology, cryptology is used
in order to ensure a secure give and take of data and to avoid hackers from
accessing data. Although this technique has existed since World War II, its
importance has increased a lot in today’s age of technology.
Difficult
to understand
Crypto means
secret language. Cryptology uses complex mathematical expressions and concepts
from computer science to create a password in form of a complex pattern, which
cannot be interpreted by an unauthorized person. Such secret messages, made up
of a combination of words, numbers and signals may seem futile at superficial
level, but actually encoding and decoding of these messages can only be done by
experts.
If your secret message is easy to understand, it
can easily be interpreted and misused to steal your data. That is why an expertise
in cryptology is essential. That is why companies employ experts from this
field to ensure security of data.
What cryptography
means
Cryptology
is the art of reading secret messages using the knowledge of languages and the
ability to interpret hidden messages. On the other hand, making use of
traditional methods along with the scientific techniques to create a secret
message is termed as cryptography. The study of this art is called as
Cryptanalysis.
Data
under vigilance!
Today,
as we work on the internet, all data is available on the server. It is
cryptology that helps us to secure this data from the hackers. Communication
taking place between two people over the internet is also protected using
cryptography. In this age of globalization, every company is keen to race ahead
of its competitor. This results in the need to secure one’s own data and to
obtain others’ crucial data. This involves use of cryptography too. Data is
encrypted before sending or receiving. Files are encrypted using various
techniques including cryptography software.
