Cloud computing (CC) is one amongst the developing technologies, which get more attention from academia as well as industries. It offers diverse benefits like sharing computing resources, service flexibility, reducing costs, etc. The Cloud Services Provider (CSP) is accountable for the data that are delivered to the cloud. The threat of seeing the stored data and using sensitive raw data by strangers is the main barrier in the utilization of cloud services. So, Data Security (DS) along with privacy is the chief issue, which is an obstacle while adopting the CC. Countless techniques are existent for ensuring data confidentiality, but they do not completely give protection to the data. To trounce these drawbacks, this paper introduces the Obfuscation (OB) based Modified Elliptical Curve Cryptography (MECC) algorithm for protecting data as of malicious attacks, which is termed as OB-MECC. Primarily, the proposed method obfuscates the data before they are uploaded to the cloud. For the OB of the data, the proposed work employs methods like substitution cipher (SC), position update, Ceaser cipher, binary conversion, 8-bit binary conversion, decimal(), two complex(), and ASCII(). Then, encryption of the obfuscated data is done with the utilization of the MECC algorithm. After encryption, the data on the cloud is retrieved. The retrieved data is then decrypted by reversing the OB and encryption process to get the actual data. The outcomes corroborate that the confidentiality and security level are maximum for the proposed OB-MECC when contrasted to the existing approaches.

Cloud computing is a developing technology which gets more attention from both the industries and academia. Once the data is sent to the cloud, the cloud service provider (CSP) alone is responsible for the data. The fear of seeing the stored and used sensitive raw data is the major barrier in the adoption of cloud services. So data security and privacy are the major issues which act as an obstacle in the adoption of cloud computing. More techniques are available to ensure the protection of data confidentiality. But they do not completely serve the purpose of protecting data. To overcome these drawbacks, this paper introduces the Obfuscation (OB) based Modified Elliptical Curve Cryptography (MECC) algorithm for protecting data from malicious attacks, which is termed as OB-MECC. First, the proposed method obfuscates the data before they are uploaded into the cloud. The proposed technique uses different methods like substitution cipher, Ceaser cipher, position update, binary conversion, 8-bit binary conversion, two complex() decimal(), and ASCII() to obfuscate the original data. After that, the obfuscated data is encrypted using the MECC algorithm. After encryption, the data is retrieved from the cloud and decrypted by reversing the encryption and obfuscation process to get the original data.

“…CC allows us to share configurable computing resources over a network on demand, requiring less effort from management or service providers to supply and release resources quickly [2]. CC is the internet-based sharing of computing resources such as storage, networking, processing power, and applications [3]. CC has permeated different industries, such as scientific research, production, education, consumption, entertainment, and so on, due to the increasing popularization of CC applications [4].…”

Cloud computing (CC) is one of the most prominent storage and computing platforms being researched nowadays. CC platforms are providing the opportunity for sharing resources, information, and services among the users of the entire world. For data storage and processing, cloud security considerations are critical. Because data in a cloud based environment must be protected from hackers, network security has been a key concern in recent years. Data should be encrypted and outsourced to the cloud to safeguard it from malicious intruders. Cryptography is essential for protecting data from various assaults and cloud storage platforms. To overcome the security threat new types of cryptography techniques can be introduced. Though a variety of firewall systems exist, there are still threats or attacks on the data or information which is transmitted over the cloud. The invention focuses on addressing the flaws that are inherent in network security by using advanced encryption techniques to encrypt data over the cloud. In this research work, a blockchain (BC) based user authentication system and improvised public-key cryptosystem are proposed which is based on Rivest-Shamir-Adleman (RSA) to support a private key cryptosystem. The proposed work comes under the following phases: user registration, login, authentication, BC, sensitive data identification, data splitting, and data security. Finally, the performance of the proposed framework in comparison with existing techniques determines strong results and proves to be more secure.
