Analysis of Cloud Computing Security with Encryption Algorithms

This report examines the critical role of encryption algorithms in securing data within cloud computing environments. It focuses on the analysis of four key algorithms: AES (Advanced Encryption Standard), RSA (Rivest-Shamir-Adleman), DES (Data Encryption Standard), and Blowfish. The report highlights the importance of data security in the cloud, addressing concerns related to data loss, privacy, and the need for robust security measures. The report also offers a brief comparison of each algorithm's functionalities and applications, emphasizing their respective strengths and weaknesses in providing data encryption. The conclusion underscores the ongoing need for strong security measures, especially considering the increased demand for cloud services and the constant evolution of security risks. This report is relevant to the MITS5002 and MITS5501 courses.

User Data Securing In Cloud
Computing Using Encryption
Algorithm

Computing of Cloud
 Cloud computing is seen to be transforming the information
technology.
 Solving a number of problems of computing which is
conventional.
 Handling the loads of peak and the software update installation.

Issues related to security
 Security of data
 Data Storage trans-coding
 Lack of existence of a single and common standard for ensuring
data integrity .

Proposed Planning
 Security algorithms are utilised for the removal of all the
concerns which are related to loss of data and privacy during the
web application upon the cloud.
Algorithms:
 RSA
 DES
 AES
 Blowfish

RSA Algorithm
 Ensures security of data in the cloud computing.
 Encryption of data for providing security.
 Securing data by allowing all the users who are authenticated for
accessing data.
 Data is stored upon the cloud.

AES Algorithm
 Used for security of information.
 It is a cipher block which is symmetric.
 Extremely analysed.
 Broadly used.
 Users are taking decision for using the services of cloud and then
finally migrates data on the cloud.

DES Algorithm
 Data Encryption Standard is a block cipher.
 Encrypts data in huge number of blocks possessing size 64bits
each.
 Both common key and algorithm utilised for the purpose of
encryption and decryption.
 Symmetric Algorithm.

Blowfish Algorithm
 Key Algorithm which is symmetric.
 Cryptographic.
 Execute about less than 5kb of the memory.
 Uses primitive operations like XOR or rather addition.
 Implementation simple.
 Simple design.

Conclusion
 Due to the increasing demand of the cloud, both the security of
cloud as well as the security of the user are the one of the
biggest concerns and all the algorithms help a lot for kinds
recent requirements and also in decreasing security risks.
