Dynamic Searchable Symmetric Encryption With Strong Security and Robustness

 Dynamic Searchable Symmetric Encryption (DSSE) is a prospective technique in the field of cloud storage for secure search over encrypted data. A DSSE client can issue update queries to an honest-but-curious server for adding or deleting his ciphertexts to or from the server and delegate keyword search over those ciphertexts to the server. Numerou...

Secure cloud data sharing encrypted system

 Cloud storage is an application of clouds that liberates organizations from establishing in-house data storage systems. However, cloud storage gives rise to security concerns. In case of group-shared data, the data face both cloud-specific and conventional insider threats. Secure data sharing among a group that counters insider threats of legitimat...

Encryption image binding with secret key

 Symmetric key cryptography is a common cryptographic technique using the same key at both the transmitter and receiver side. The main advantage of symmetric key encryption is its less computational cost compared to its counterpart-public key encryption. In this work a new symmetric key encryption scheme is proposed. Rather than using normal binary ...

Secure data transmission in network (inside attack)

 In the present scenario, any type of communication over the internet and other network applications need to be secure due to their increasing utility. For this task, lots of algorithms for security have been implemented and used so far. With these developments, attackers have also come up with the new ideas to penetrate the communication mediums. T...

Ranked key word search

 In today’sera a new generation of technology is transforming the world of computing. Advances in internet based data storage, processing and services collectively known as cloud computing have emerged to complement the traditional model of running software and storing data on personal devices or on premise networks. Today cloud computing provide hi...

Performance Evaluation of Symmetric Cryptographic Algorithms in resource constrained hardware for Wireless Sensor Networks

 Wireless sensor networks (WSN) allow to exchange information and to take immediate and remote actions in natural, industrial, military or domestic environment systems. These networks are vulnerable to cyber-attacks, hence, they are vulnerable to being intercepted, interrupted or modified. However, for the last twenty years, the amount of informatio...

Policy-based Broadcast Access Authorization for Flexible Data Sharing in Clouds

 Cloud storage services allow data owners to outsource their potentially sensitive data (e.g., private genome data) to remote cloud servers in a ciphertext form. To enable data owners to further share the data encrypted in ciphertexts, many proxy re-encryption (PRE) schemes are proposed. However, most schemes only support single-recipient or coarse-...

Data Access Control in Cloud Computing Flexible and Receiver Extendable

 Broadcast encryption provides a promising technique of data access control for specified users in cloud computing. A data uploader can generate a ciphertext for a set of chosen users such that only the intended users are able to learn the data content. However, with the rapidly increasing of collaboration between users, it is desired to extend the ...

SECURE DATA SHARING FOR MOBILE CLOUD COMPUTING USING BLOWFISH ALGORITHM

 Cloud computing is a great innovation in the world of computing, there also exist downsides of cloud computing. These most important challenges are security and privacy of data on the cloud, check availability of data on the cloud. For these problems, data storage security refers to the security of data on the storage media. Security is an importan...

Hybrid Cryptography and Stenography Healthcare Application

 This paper presents a technique for secret communication using Cryptography and Steganography. In this paper, the secret message of different size is hidden into an image for making the system more secure. The only authorized users can hide and extract the secret message. The secret messages of different size are used to test the system and the sys...
