Secure data transmission
or sharing data through internet without exposing data to threats is a
main concern of modern era. We share data over internet in formats
like text, pictures and videos. While transferring data, we have to be
sure that data we sent are not exposed to unauthorized threats and
integrity of the content is not harmed.
To achieve this purpose
many ciphering techniques or cryptographic methods are being used
these days, we use these methods to hide or scramble data we share in
a way that only the receiver will be able to access the content. One
of the futuristic cryptographic methods that can be used is DNA
Cryptography. DNA Cryptography uses molecular science and
biotechnology to create safer, robust and efficient environment for
data transmission. DNA cryptography can be seen in mobile networking
and cloud computing.
IIn 2002, LeonardMax
Adleman introduced DNA computing to the world. DNA cryptographic
algorithms uses one-time pad and the key is obtained by using DNA
bases.in order to increase security of the cipher text, DNA look up
tables were also established.
DNA or deoxyribonucleic acid, stores all the information about body
features of any organism. DNA is unique for each individual. The bases
and bonding in DNA structure plays an important role in DNA computing
and cryptography.
In DNA cryptography the data is secured either inside the DNA (in DNA
microdots) or using DNA sequences to create encrypted texts which can
only be broken if the correct sequence of DNA bases is known.
DNA cryptography solves weak spots problems in storing ciphers and
helps to solve some primary NP problems giving hope in creating an
unbreakable algorithm.
Cloud computing allows computer programs and stand-alone data to be
transferred to a virtual server or the Web for easy user access. Cloud
computing is considered a next-generation technology that has
revolutionized the computer industry. Cloud computing provides users
with a massive infrastructure to perform their tasks and store data.
Cloud computing consists of two types of models, the service model (PaaS,
SaaS, IaaS) and the deployment model (public, private, hybrid).
Normally the cloud client does not want to work with a single cloud
provider in due to compatibility issues availability problem and
sometimes insider problem. They therefore use several cloud services
according to their request. In the area of IT and computer security,
application and service security is a more promising area of research.
Cloud users transfer their applications and data to the cloud
environment. It is therefore necessary that the security methods used
in the cloud be better than the traditional methods because of the
high security risks and issues. Unauthorized access to data, network
and applications by an unauthorized person is the cause of the lack of
security and protection of the cloud environment, which affects the
productivity and growth of the organization. Determining the level of
risk sustainability and focusing on reducing these risks is one of the
most important parts of the cloud that cannot be disregarded by the
cloud service provider. Cloud computing has some important features
that surpass the functionality of traditional services and contribute
to the growth of the contemporary IT sector.
As we all know today, data on the Internet is growing unlimitedly.
Several serious problems are raised due to that and must be treated
with care. Out of these, safety is one of the main concerns. Many
organizations and individuals are now using cloud storage technology
to back up and share their data over the Internet. Cloud systems are
secured using various cryptographic technologies such as RSA, AES or
HCC, etc. However, these technologies may breakdown in the future when
the data to be encrypted is huge and bulky. DNA Computing can become
practical when it is necessary to solve such huge data encryption
problems, as DNA has been proven to be one of the hearty encryption
data storage devices created by Mother Nature, which effectively
provides information to our body and brain on various activities, etc.
We will discuss here one of the possible ways to implement DNA-based
cryptographic technique to encrypt cloud data, increase accuracy and
reduce processing time.
DNA (deoxyribonucleic acid) is a kind of genetic material that helps
to transfer information contained in living organisms, such as small
organisms (viruses) to the complex (human). DNA is a double helix
structure proposed by Watson and Crick. This DNA structure is made by
a long chain of polymer called nucleotides. Each nucleotide composed
of three essential components are nitrogenous base, sugar and
phosphate. Nitrogen bases consist essentially of two types of
pyrimidine and purine bases (cytosine, adenine, guanine and thymine).
Advances in technology and the increasing use of the Internet are
improving the storage capacity of data as standalone storage devices
or virtual storage devices. But this progress also poses some problems
mainly related to data security. In cloud computing, we process a
quantity of data tints stored in remote locations (virtual servers).
Security is therefore a more important concern of cloud computing.
Here we are working with a new idea to secure data on the cloud with
the help of DNA cryptography.
Data security is a more promising area of the computer industry.
Unlimited use of the Internet and the new technological invention are
forcing people to think about the security of data or Internet data.
In this article, a new approach to DNA cryptography to secure data in
the cloud is discussed. However, less research has been done in the
field of DNA cryptography.
