Security-control methods for statistical databases: a comparative study

by Nabil R. Adam, John C. Wortmann - ACM Computing Surveys , 1989
"... This paper considers the problem of providing security to statistical databases against disclosure of confidential information. Security-control methods suggested in the literature are classified into four general approaches: conceptual, query restriction, data perturbation, and output perturbation. ..."

Privacy Preserving and Security Control Method for Statistical Database

by S. Udhaya Kumar, N. Partheeban
"... Abstract---As organizations increase their reliance on, possibly distributed, information systems for daily business, they become more vulnerable to security breaches even as they gain productivity and efficiency advantages. The availability of huge numbers of databases recording a large variety of ..."

Role-Based Access Control

by David Ferraiolo, Richard Kuhn - In 15th NIST-NCSC National Computer Security Conference , 1992
"... While Mandatory Access Controls (MAC) are appropriate for multilevel secure military applications, Discretionary Access Controls (DAC) are often perceived as meeting the security processing needs of industry and civilian government. This paper argues that reliance on DAC as the principal method of a ..."

Secure Execution Via Program Shepherding

by Vladimir Kiriansky , Derek Bruening, Saman Amarasinghe , 2002
"... We introduce program shepherding, a method for monitoring control flow transfers during program execution to enforce a security policy. Program shepherding provides three techniques as building blocks for security policies. First, shepherding can restrict execution privileges on the basis of code or ..."

Abstract Information Protection in Dynamic Statistical Databases

by Shiuh-pyng Shieh, Chern-tang Lin
"... A statistical database (SDB) is a database that contains sensitive records describing individuals but only statistical information is available. There are many inference control methods proposed to protect SDBs. In this article, we will briefly introduce three general approaches: conception, perturb ..."

will present an efficient audit scheme, which is a query-restriction-based security-control method for protecting dynamic SDBs. This scheme guarantees the security of SDBs and needs less time and storage requirements than the traditional schemes while database systems are dynamically updated. 1.

Secure Verification of Location claims

by Naveen Sastry, Umesh Shankar, David Wagner - In Proceedings of the ACM Workshop on Wireless Security (WiSe , 2003
"... With the growing prevalence of sensor and wireless networks comes a new demand for location-based access control mechanisms. We introduce the concept of secure location verification, and we show how it can be used for location-based access control. Then, we present the Echo protocol, a simple method ..."

Automated trust negotiation

by William H. Winsborough, Ninghui Li - In DARPA Information Survivability Conference and Exposition, volume I , 2000
"... Exchange of attribute credentials is a means to establish mutual trust between strangers wishing to share resources or conduct business transactions. Automated Trust Negotiation (ATN) is an approach to regulate the exchange of sensitive information during this process. It treats credentials as poten ..."

to be protected in ATN? ” and “what are the security requirements? ” are not adequately answered. As a result, many prior methods of ATN have serious security holes. We introduce a formal framework for ATN in which we give precise, usable, and intuitive definitions of correct enforcement of policies in ATN. We

Improved proxy re-encryption schemes with applications to secure distributed storage

by Giuseppe Ateniese, Kevin Fu, Matthew Green, Susan Hohenberger - IN NDSS , 2005
"... In 1998, Blaze, Bleumer, and Strauss proposed an application called atomic proxy re-encryption, in which a semi-trusted proxy converts a ciphertext for Alice into a ciphertext for Bob without seeing the underlying plaintext. We predict that fast and secure re-encryption will become increasingly popu ..."

popular as a method for managing encrypted file systems. Although efficiently computable, the wide-spread adoption of BBS re-encryption has been hindered by considerable security risks. Following recent work of Ivan and Dodis, we present new re-encryption schemes that realize a stronger notion of security

Achieving secure, scalable, and fine-grained data access control in cloud computing

ON SECURITY OF STATISTICAL DATABASES

by R. Ahlswede, H. Aydinian
"... A statistical database (SDB) is a database that is used to return statistical information derived from the records to user queries for statistical data analysis. Sometimes, by correlating enough statistics, confidential data (stored in a SDB) about an individual can be inferred. Examples of confiden ..."

the available queries. One of the security-control methods suggested in the literature consists of query restriction: the security problem is to limit the use of the SDB, introducing a control mechanism, such that no protected data can be obtained from the available queries. Chin and Ozsoyoglu [7] introduced a
