Query Processing Performance and Searching Over Encrypted Data By Using An Efficient Algorithm
Data is the central asset of today’s dynamically operating organization and their business. This data is usually stored in database. A major consideration is applied on the security of that data from the unauthorized access and intruders. Data encryption is a strong option for security of data in database and especially in those organizations where security risks are high. But there is a potent...
متن کاملPrivate Key based query on encrypted data
Nowadays, users of information systems have inclination to use a central server to decrease data transferring and maintenance costs. Since such a system is not so trustworthy, users' data usually upkeeps encrypted. However, encryption is not a nostrum for security problems and cannot guarantee the data security. In other words, there are some techniques that can endanger security of encrypted d...
متن کاملTop-k Query Processing Over Outsourced Encrypted Data
Nowadays, cloud data outsourcing provides users and companies with powerful capabilities to store and process their data in third-party data centers. However, the privacy of the outsourced data is not guaranteed by the cloud providers. One solution for protecting the user data against security attacks is to encrypt the data before being sent to the cloud servers. Then, the main problem is to ev...
متن کاملQuery Processing Performance on Encrypted Databases by Using the REA Algorithm
Encryption in database systems is an important topic for research, as secure and efficient algorithms are needed that provide the ability to query over encrypted database and allow optimized encryption and decryption of data. Clearly, there is a compromise between the degree of security provided by encryption and the efficient querying of the database, because the operations of encryption and d...
متن کاملEfficient SUM Query Processing over Uncertain Data
SUM queries are crucial for many applications that need to deal with probabilistic data. In this paper, we are interested in the queries, called ALL_SUM, that return all possible sum values and their probabilities. In general, there is no efficient solution for the problem of evaluating ALL_SUM queries. But, for many practical applications, where aggregate values are small integers or real numb...
