Development of the Lock Protocol for DEPSKY Storage System

Author: NASCIMENTO, P. S.; FREITAS, A. E. S.

Abstract: Data management in environments based on several clouds (cloud-of-clouds) should be dependable and secure. DEPSKY may assure that characteristics through mechanisms as cryptography and data replication, however DEPSKY does not support concurrent writing, a desirable functionality for many applications. This paper presents the development and a performance analysis of a lock algorithmfor DEPSKY storage system. The paper also presents validation test and performance test of the algorithm. Such protocol allows concurrent writing, through a low contention lock mechanism that uses lock filesfi to dene who is allowed to write in a data unit.

Keywords: Cloud Computing, Replication, Security.
