Abstract

The use of cloud computing has increased rapidly in many organizations and it also deployed in technologies like 3G, 4G and pervasive applications. Ensuring the security of cloud computing is a major factor in the cloud computing environment as users often store sensitive information with cloud storage providers (CSP), but these providers may be untrusted. Even though a TPA audits the users data with correctness and integrity, dealing with single cloud providers is predicted to become less popular with service availability failure, possibility of malicious insiders and Byzantine faults in the single cloud.  A movement towards Multi-Clouds or in other words inter-clouds or clouds- of- clouds has emerged recently; hence we need to protect the user data in Multi-Clouds with greater security in the form of public batch auditing and dynamic certification to perform continuous monitoring from single to Multi-Clouds, by this, it  is to implement Cipher text – Policy Attribute Based Encryption(CP-ABE)[6] to achieve secure data sharing and also provides forward and data sharing and also provides forward and backward security  in cloud computing to improve the security and performance with many number of users using the single to multi cloud environment.

Abstract

Wireless sensor networks are often deployed in hostile environments, where an adversary can physically capture some of the nodes. Once a node is captured, the attacker can re-program it and replicate the node in a large number of replicas, thus easily taking over the network. The detection of node replication attacks in a wire- less sensor network is therefore a fundamental problem. Compared to the extensive exploration on the defense against node replication attacks in static networks, only a few solutions in mobile networks have been presented. Moreover, while most of the existing schemes in static networks rely on the witness-finding strategy, which cannot be applied to mobile networks, the velocity-exceeding strategy used in existing schemes in mobile networks incurs efficiency and security problems. In this paper Localized algorithms are proposed to resist node replication attacks in mobile sensor networks. The Merits of proposed algorithms are, it can effectively detect the node replication in localized manner. These algorithms are, also avoid network-wide synchronization and network-wide revocation.
