2. Problem Area
In this document we tried to overcome the security
issue faced by cloud during file transfer. Despite of vast
researches made to overcome these issues, there is no
perfect solution till determined. We took this as a
problem and proposed a simple solution to overcome
the issues through DYNAMIC ENCRYPTION
algorithms. Here we use two algorithms namely:
1. AES(Advanced Encryption Standard)
2. RSA(Rivest Shamir Adleman)
3. Problem Area(Cont..)
Where AES is a symmetric algorithm used in server
side for dynamic encryption and RSA is a asymmetric
algorithm used in client side for one time encryption.
This document includes same existing procedure for
easy request and respond from client and server. While
client request for the particular file or data first the file
is decrypted with AES and again it is decrypted with
RSA algorithm in client side.
4. Solution
The topic SCUDE briefly explains Storing and
transferring data in Cloud securely Using Dynamic
Encryption. The encrypted data in cloud server is
again dynamically encrypted with respect to time.
Symmetric key algorithms are used to encrypt the data
which rest on cloud, while transferring the data
asymmetric key algorithms are used.
The Dynamic Encryption involves two cryptographic
algorithms namely RSA(Asymmetric algorithm) and
AES(Symmetric algorithm).
6. Solution(Cont...)
And for decryption the same algorithm is used in
reverse process.
The goal of our project is to provide more security for
data, even though it has some drawbacks and
constraints which we will solve in the upcoming
modules.
The main aim of SCUDE is to overcome the Data
Insecurity (During File Transfer).
7. Impacts
This document overcomes five main issues:
1. Data protection in motion
2. Encryption key management
3. Access controls
4. Long-term resiliency of the encryption system
5. Robust Security
Through this project we can avoid data insecurity and
data loss using cryptographic algorithms.
8. Conclusion
The main advantage is preventing hacking and
cracking of data from unauthorized source.
Reliability and scalability can be improved.
This algorithm provides high security with firewalls.
Data breach and data loss is the major drawback in the
existing system which has been overcome in SCUDE.
