1505287243 IEEE 2017-2018 JAVA PROJECTS ABSTRACT RAAC: ROBUST AND AUDITABLE ACCESS CONTROL WITH MULTIPLE ATTRIBUTE AUTHORITIES FOR PUBLIC CLOUD STORAGE ABSTRACT:- Data access control is a challenging issue in public cloud storage systems. Cipher text-Policy Attribute-Based Encryption (CP-ABE) has been adopted as a promising technique to provide flexible, fine-grained and secure data access control for cloud storage with honest-but-curious cloud servers. However, in the existing CP-ABE schemes, the single attribute authority must execute the time-consuming user legitimacy verification and secret key distribution, and hence it results in a single-point performance bottleneck when a CP-ABE scheme is adopted in a large-scale cloud storage system. Users may be stuck in the waiting queue for a long period to obtain their secret keys, there by resulting in lowefficiency of the system. Although multiauthority access control schemes have been proposed, these schemes still cannot overcome the drawbacks of single-point bottleneck and low efficiency, due to the fact that each of the authorities still independently manages a disjoint attribute set. In this paper, we propose a novel heterogeneous framework to remove the problem of single-point performance bottleneck and provide a more efficient access control scheme with an auditing mechanism. Our framework employs multiple attribute authorities to share the load of user legitimacy verification. Meanwhile, in our scheme, a CA (Central Authority) is introduced to generate secret keys for legitimacy verified users. Unlike other multiauthority access control schemes, each of the authorities in our scheme manages the whole attribute set individually. To enhance security, we also propose an auditing mechanism to detect which AA (Attribute Authority) has incorrectly or maliciously performed the legitimacy verification procedure. Analysis shows that our system not only guarantees the security requirements but also makes great performance improvement on key generation. single point performance bottlenecklegitimacy verification procedurehonest but curious cloud serversmultiple attribute authoritiestime consuming user legitimacy view more Query Share Tweet share google+ pinterest LinkedIn email Message Your Email/Number

1505280438 IEEE 2017-2018 JAVA PROJECTS ABSTRACT ON THE SECURITY OF DATA ACCESS CONTROL FOR MULTIAUTHORITY CLOUD STORAGE SYSTEMS ABSTRACT:- Data access control has becoming a challenging issue in cloud storage systems. Some techniques have been proposed to achieve the secure data access control in a semi trusted cloud storage system. Recently, Keying et al. Proposed a basic data access control scheme for multiauthority cloud storage system (DAC-MACS) and an extensive data access control scheme (EDAC-MACS). They claimed that the DAC-MACS could achieve efficient decryption and immediate revocation and the EDAC-MACS could also achieve these goals even though no revoked users reveal their Key Update Keys to the revoked user. However, through our cryptanalysis, the revocation security of both schemes cannot be guaranteed. In this paper, we first give two attacks on the two schemes. By the first attack, the revoked user can ea vesdrop to obtain other users’ Key Update Keys to update its Secret Key, and then it can obtain proper Token to decrypt any secret information as a no revoked user. In addition, by the second attack, the revoked user can intercept Cipher text Update Key to retrieve its ability to decrypt any secret information as a no revoked user. Secondly, we propose a new extensive DAC-MACS scheme (NEDAC-MACS) to withstand the above two attacks so as to guarantee more secure attribute revocation. Then, formal cryptanalysi s of NEDAC-MACS is presented to prove the security goals of the scheme. Finally, the performance comparison among NEDAC-MACS and related schemes is given to demonstrate that the performance of NEDAC-MACS is superior to that of DACC, and relatively same as that of DAC-MACS. multiauthority cloud storagesecure attribute revocationextensive DAC MACS schemeJAVA PROJECTS ABSTRACTperformance comparison view more Query Share Tweet share google+ pinterest LinkedIn email Message Your Email/Number submit 1511845295 ANDROID PROJECTS TITLES – 2017-2018 Understanding Smartphone Sensor and App Data for Enhancing the Security of Secret Questions This projects will be emailed to the students who interested to do the project by our team Smartphone SensorPROJECTS TITLESinterestedEnhancingApp Data view more Query Share Tweet share google+ pinterest LinkedIn email Message Your Email/Number submit 1511845125 ANDROID PROJECTS TITLES – 2017-2018 ShakeIn: Secure User Authentication of Smartphones with Habitual Single-handed Shakes This projects will be emailed to the students who interested to do the project by our team Secure User AuthenticationPROJECTS TITLESSmartphonesinterestedstudents view more Query Share Tweet share google+ pinterest LinkedIn email Message Your Email/Number Next Previous
