Summarization of Data Security and Encryption in Cloud Computing

Abstract

The development of intelligent algorithm in cloud computing network service can well fit the many nodes and links among cloud computing network service systems. Approximate calculation on reliability is especially important in network era of large-scale cloud computing. This thesis focuses on the date security and encryption in cloud computing and proposes the security strategy of updating dual Cache driven by time. Strategy based on Cache configuration and time division can be used to update Cache driven by time, so as to solve the SCA (side channel attacks) during cloud computing. The strategy for updating Cache driven by time is realized through random N-time cached updates for each user in time period T, aiming to disturb the attacker’s confirmation about whether Cache is hit and make the attacker use invalid information in side channel information process Thus, the safety data in Cache under cloud computing environment can be protected and users shall no longer worry about the data in cloud computing.
