Secure Group Communication for Cassandra
نویسنده
چکیده
Cassandra is a distributed NoSQL system providing high scalability and availability. However, it has many security vulnerabilities. Especially the information about internal cluster structure and transferred data can be exposed by outside attackers. In this paper, we present a novel way to enhance Cassandra security by means of group key. The group key model is designed considering Cassandra’s physical structure, and it is a decentralized model where the nodes are divided into several subgroups. The proposed model helps protecting internal cluster from outside by confirming the node’s cluster membership.

In this paper, we analyze the secure connectivity in Shotgun cellular systems (SCS: Wireless communication systems with randomly placed base stations) by Poisson intrinsically secure communication graph (IS-graph), i.e., a random graph which describes the connections that are secure over a network. For a base-station in SCS, a degree of secure connections is determined over two channel models: ...

Typical cryptography schemes are not well suited for low complexity types of equipment, e.g., Internet of things (IoT) devices, as they may need high power or impose high computational complexity on the device. Physical (PHY) layer security techniques such as beamforming (in multiple antennas systems) are possible alternatives to provide security for such applications. In this paper, we consid...
