Secure and practical outsourcing of linear programming in cloud computing

2011 Proceedings IEEE INFOCOM, 2011
Cloud computing enables customers with limited computational resources to outsource large-scale computational tasks to the cloud, where massive computational power can be easily utilized in a pay-per-use manner. However, security is the major concern that prevents the wide adoption of computation outsourcing in the cloud, especially when end-user's ...

Verifiable Search for Dynamic Outsourced Database in Cloud Computing

2015 10th International Conference on Broadband and Wireless Computing, Communication and Applications (BWCCA), 2015
The notion of database outsourcing enables the data owner to delegate the database management to a cloud service provider (CSP) that provides various services to users of the database. It is inevitably to bring in new security challenges such as data privacy and query integrity.

A Survey on the Integrity Checking of Outsourced Data in Cloud Computing

2015 IEEE 12th Intl Conf on Ubiquitous Intelligence and Computing and 2015 IEEE 12th Intl Conf on Autonomic and Trusted Computing and 2015 IEEE 15th Intl Conf on Scalable Computing and Communications and Its Associated Workshops (UIC-ATC-ScalCom), 2015
With the development of cloud computing, a large number of individuals and companies transfer their data and business to cloud computing. But the management of the data and services of the cloud may not be fully trustworthy. How to ensure the integrity of data stored in cloud attracts more and more attention.

Data security in cloud computing and outsourced databases

2016 International Conference on Electrical, Electronics, and Optimization Techniques (ICEEOT), 2016
We introduce a model for provable data possession (PDP) that allows a client that has stored data at an untrusted server to verify that the server possesses the original data without retrieving it. The model generates probabilistic proofs of possession by sampling random sets of blocks from the server, which drastically reduces I/O costs.

Outsourced Attribute-Based Signcryption in the Cloud Computing

2018 15th International Computer Conference on Wavelet Active Media Technology and Information Processing (ICCWAMTIP), 2018
An Attribute-Based Signcryption is a natural extension of attribute-based encryption and attribute-based signature where we have the message confidentiality and authenticity together. However, due to the high expressiveness of ABE policies the computational complexities of ABE key issuing and decryption are getting prohibitively high and the heavy ...

Lightweight Verifiable Auditing for Outsourced Database in Cloud Computing

2017
Database outsourcing in Cloud Computing enables the data owner to store the data on cloud and assign the management to a cloud service provider (CSP), which provides various cloud services to the users. However, outsourcing database to cloud poses many challenges. One of the major concerns is confidentiality of the data.

Design of an Efficient Verification Scheme for Correctness of Outsourced Computations in Cloud Computing

2015
As cloud computing allows consumers or clients to store and delegate their sensitive data, cloud service providers have a lot of power over this data. Hence, the service providers in cloud computing cannot be trusted. To protect itself from being cheated on, by the untrusted service provider, the client needs a way to verify the correctness of ...

Efficient Outsourcing of Modular Exponentiations in Cloud Computing

2019
Cloud computing is a user-centered computing service. A majority of cloud computing services are deployed through outsourcing. Modular exponentiation is one of the most complex computations in public key based cryptographic schemes. It is useful to reduce the computation cost of the clients by using outsourcing computation. In this paper, we propose an
