Abstract

The cloud database as a service helps in several internet based applications, but it faces several confidentiality problems. Hence to improve data confidentiality in terms of scalability and availability, a new model namely Security as a Service (SECaaS) model is being introduced that uses quantum encryption scheme. Quantum cryptography is rapidly developing these days due to its high secrecy power in terms of key generation and key distribution. Hence this quantum encryption scheme is used in layered concept that helps to improve data confidentiality and secrecy.

A Novel Scheme for Data Security in Cloud Computing using Quantum Cryptography

Geeta Sharma, Sheetal Kalra

Cloud computing manifests exceptional capacity to facilitate easy to manage, cost effective, flexible and powerful resources across the internet. Due to maximum and shared utilization of utilization of resources, cloud computing enhances the capabilities of resources. There is a dire need for data security in the wake of the increasing capabilities of attackers and high magnitude of sensitive data. Cryptography is employed to ensure secrecy and authentication of data. Conventional information assurance methods are facing increasing technological advances such as radical developments in mathematics, potential to perform big computations and the prospects of wide-ranging quantum computations. Quantum cryptography is a promising solution towards absolute security in cryptosystems. This paper proposes integration of Advanced Encryption Standard (AES) algorithm with quantum cryptography. The proposed scheme is robust and meets essential security requirements. The simulation results show that the Quantum AES produces complex keys which are hard to predict by adversaries than the keys generated by the AES itself.

Secure data access control for multi-authority Quantum based cloud storage

K. Vidya, A. Backia Abinaya

An efficient way of ensuring security in cloud is to give secure data access control among untrusted cloud server. Hence to improve the security, a new system could be introduced such as Quantum Security Scheme which invokes Quantum gates for encryption purpose. Quantum cryptography has been rapidly developing these days due to its efficient service which is provided by means of key generation and key distribution. Quantum Ciphertext-Policy Attribute Based Encryption (QCP-ABE) is a promising technique for data access control on encrypted data. This scheme also achieves mutual authentication among those authorities involving in the system and it also achieves both forward and backward security.

Securing Cloud Computing Environment using a New Trend of Cryptography

Omer K. Jasim Mohammad, Safia Abbas, El-Sayed M. El-Horbaty +1 more

Cloud computing is an internet-based computing, where shared resources, software, and information are provided with consumers on-demand. They guarantee a way to share distributed resources and services that belong to different organizations. In order to build secure cloud environment, data security and cryptography must be assured to share data through distributed environment. So, this paper provides more flexibility and secured communication environment by deploying a new cryptographic service. This service entails both Quantum Key Distribution (QKD) and enhanced version of Advanced Encryption Standard (AES). Moreover, this service solves the key distribution and key management problems in cloud environment which emerged through the two implemented modes, on-line and off-line modes.

Cloud Computing Cryptography "State-Of-The-Art"

Omer K. Jasim Mohammad, Safia Abbas, El-Sayed M. El-Horbaty +1 more

Cloud computing technology is very useful in present day to day life, it uses the internet and the central remote servers to provide and maintain data as well as applications. Such applications in turn can be used by the end users via the cloud communications without any installation. Moreover, the end users’ data files can be accessed and manipulated from any other computer using the internet services. Despite the flexibility of data and application accessing and usage that cloud computing environments provide, there are many questions still coming up on how to gain a trusted environment that protect data and applications in clouds from hackers and intruders. This paper surveys the “keys generation and management” mechanism and encryption/decryption algorithms used in cloud computing environments, we proposed new security architecture for cloud computing environment that considers the various security gaps as much as possible. A new cryptographic environment that implements quantum mechanics in order to gain more trusted with less computation cloud communications is given.

Quantum-Enhanced Security Advances for Cloud Computing Environments

Devulapally Swetha, Shaik Khaja Mohiddin

Recent developments in quantum-enhanced security have demonstrated encouraging promise for enhancing cloud computing environments' security. Utilizing quantum physics, in particular Quantum Key Distribution (QKD), provides a new method for generating cryptographic keys and improves cloud data transport security. The present study offers a thorough investigation of the integration of QKD with conventional encryption techniques, including Advanced Encryption Standard (AES), in order to tackle the dynamic cyber security scenario in cloud computing. The approach entails combining AES for encryption and decryption procedures and establishing a QKD layer within the cloud architecture to produce true quantum keys utilizing Quantum in Cloud technology. Data transmission security is greatly improved by the smooth integration of AES with QKD-generated keys, guaranteeing confidentiality, integrity, and authenticity. In addition, strong key management practices are put in place to handle cryptographic keys safely at every stage of their lifespan, reducing the possibility of unwanted access or interception. The suggested approach successfully addresses the difficulties presented by cyber threats by offering a robust and flexible means of enhancing security in cloud-based systems. Using both traditional and quantum encryption methods, this strategy provides a strong barrier against cyber-attacks, data leaks, and other security flaws. After 70 simulation rounds, the suggested strategy, which is implemented using the QKD-AES framework in Python software, achieved a data access rate of 820 MB/s. In addition to providing an accurate and quantitative assessment of the performance, this also exhibits a high data access rate attained under simulated conditions. At 15 milliseconds, the key generation time was achieved with efficiency, guaranteeing the quick creation of secure cryptographic keys in cloud environments. Overall, there is a lot of potential in using quantum-enhanced security techniques to protect sensitive data and guarantee the integrity of cloud computing infrastructures.
