2. ABSTRACT
● Vast amounts of sensitive and confidential information is generated by the
pharmaceutical industry in the form of medicine formulas, employee
information, medical records. The industry needs to ensure that their information
is kept secure from cybercrime.
● Pharmaceutical industries is a domain where there are high chances of security
breaches and applying Homomorphic Encryption can help minimize them.
● We aim to design a working system that deals with such information the
Homomorphic way. We try to implement a web-application that allows
employees of a particular pharmaceutical company to update sensitive data
homomorphically that’s stored on the cloud or database server.
3. NEED ANALYSIS
● The Pharmaceutical industry needs to ensure that their information is kept secure from
cybercrime. Cyber criminals can have devastating effects on the pharmaceutical industry
by accessing or destroying their information.
● Due to these reasons it has become mandatory for the pharmaceutical industry to develop
an Information Security Management system.
● We implement a web-application that allows employees of a particular pharmaceutical
company to update sensitive data homomorphically that’s stored on the cloud or database
server. Here the employee on a daily basis updates the amount of particular components
used, through the web portal which is reflected on the data stored in the databases
homomorphically

Homomorphic encryption
provides high-level security
to the data being transmitted
in electronic voting systems.
This ensures that the data is
not tampered with or
compromised during
transmission.
Homomorphic encryption
may not be compatible with
all electronic voting systems
or platforms. This may limit
the adoption of this
technology in some cases.

It can be applied to various
use cases, including data
storage, sharing, and
processing.
Only described the
mathematical concept and
theory of homomorphic
encryption

It consequently covers design
fundamentals and security
properties of
FHE and describes the main
FHE schemes based on
various mathematical
problems.
FHE is a complex and
computationally intensive
process, requiring significant
computational resources to
perform even simple
computations.

The proposed improved AES
algorithm can enhance the
security of data encryption
by incorporating additional
security features.
The paper does not present
any real-world testing or
performance analysis of the
proposed algorithm, making
it unclear how it performs in
practice.

It allows multiple parties to
jointly perform computation
on encrypted data without
compromising the privacy of
data owners.
The paper does not provide a
detailed analysis of the
security of the proposed
algorithm against various
attacks.

Computing System” , 2021 International Conference

With the use of symmetric
key encryption, the data
uploaded on the cloud is
secured with an extra layer of
protection. This makes it
difficult for unauthorized
users to access or tamper with
the data.
Symmetric key encryption
requires the management of
keys, which can be
challenging for large
organizations.

case of Paillier Homomorphic Algorithm for
Electronic-Voting Systems” published on 11
december 2021.
The proposed e-voting system
using Paillier cryptosystem
provides enhanced security
for online voting, ensuring
that the integrity and
confidentiality of votes are
maintained.
An e-voting system based on
Paillier cryptosystem may
require additional security
measures to prevent potential
attacks, such as insider attacks
or denial-of-service attacks.

Homomorphic Encryption Schemes for Enhancing
Security in Fog Computing”International conference
published on Sep 2020
Homomorphic encryption can
be used in Fog Computing to
ensure that data is secure
when being processed on edge
devices.
Key management involves
secure key distribution and
periodic key rotation, which
can be time-consuming and
costly.

The paper covers various
encryption mechanisms that
are used to secure cloud
storage systems, such as
symmetric and asymmetric
key encryption, homomorphic
encryption, and proxy re-
encryption.
No practical implementation

13. CONCLUSION
We were able to implement Homomorphic operations as intended in a working prototype.
As discussed above, we designed an application that allows employees of a particular
pharmaceutical company to update sensitive data on the server cloud/database without
decrypting any part of the encrypted data that is stored on the cloud/database. Since keys
play an important role in carrying out these Homomorphic operations it was important to
secure these keys which were unique to all the users accessing the application. For that, we
designed a secure key generation and storage functionality which stored the keys on the
server in its encrypted form and were only accessible based on login credentials which in
itself were unique, hence adding an additional layer of security to the application.
