Secure Private Key Distribution for Dynamic Groups in the Cloud

Miss. Sonali S. Goral
2018 International Journal for Research in Applied Science and Engineering Technology  
This gives the protection from the collusion attack that means user cannot get original data files even if they join with untrusted cloud.  ...  To achieve a functional and low-budget approach for sharing data within groups with group members in the cloud with not only low maintenance but also low management cost, the system can be proposed.  ...  It provides data storage with low cost and it should be available over the Internet all the time. The security is the most important factor in the cloud computing.  ...

A Cloud design for user-controlled storage and processing of sensor data

Rene Hummen, Martin Henze, Daniel Catrein, Klaus Wehrle
2012 4th IEEE International Conference on Cloud Computing Technology and Science Proceedings  
However, sensor data often contains privacy-relevant or otherwise sensitive information. For current Cloud platforms, the data owner looses control over her data once it enters the Cloud.  ...  Ubiquitous sensing environments such as sensor networks collect large amounts of data. This data volume is destined to grow even further with the vision of the Internet of Things.  ...  The responsibility for the content of this publication lies with the authors.  ...

Secure deletion from inverted indexes on compliance storage

Soumyadeb Mitra, Marianne Winslett
2006 Proceedings of the second ACM workshop on Storage security and survivability - StorageSS '06  
Since most of the modern WORM devices are built on top of magnetic media, they also support a secure deletion operation by associating expiration time with files.  ...  Secure retention, however, is only a part of a document's lifecycle: It is often crucial to delete documents after its mandatory retention period is over.  ...  To prevent join attacks, the document ID is XORED with the hash of the keyword before encryption.  ...
