Opis:
Nowadays, the growth and complexity of functionalities of current information systems, especially dynamic, distributed and heterogeneous information systems, makes the design and creation of such systems a difficult task and at the same time, strategic for businesses. A very important stage of data protection in an information system is the creation of a high level model, independent of the software, satisfying the needs of system protection and security. The process of role engineering, i.e. the identification of roles and setting up in an organization is a complex task. The paper presents the modeling and design stages in the process of role engineering in the aspect of security schema development for information systems, in particular for dynamic, distributed information systems, based on the role concept and the usage concept. Such a schema is created first of all during the design phase of a system. Two actors should cooperate with each other in this creation process, the application developer and the security administrator, to determine the minimal set of user’s roles in agreement with the security constraints that guarantee the global security coherence of the system.

Opis:
The paper presents the design and the rationale behind a simple verification protocol for autonomous verification modules, and the architecture enabling use of such modules. The architecture assumes strict separation of all personal metadata and the actual verification data. The paper also describes a prototype implementation of the protocol and its extension enabling the state of the module to be monitored from the main system. The proposed design solves the problem of using advanced verification methods, especially biometric ones, in systems where direct implementation is not possible due to hardware incompatibilities, insufficient resources or other limitations.

Opis:
Artykuł przedstawia analizę nowych zastosowań biometrii w obszarze bezpieczeństwa. Są dwa najważniejsze zastosowania tej metody. Po pierwsze, poza jej wykorzystaniem w dokumentach, takich jak dowody osobiste czy paszporty, biometria może być z powodzeniem stosowana jako narzędzie fizycznej kontroli dostępu w przedsiębiorstwach o znaczeniu strategicznym w systemie bezpieczeństwa publicznego. Po drugie, może znaleźć zastosowanie w bankowości elektronicznej – jako instrument identyfikacji klienta i autoryzacji transakcji. W obu przypadkach wykorzystanie biometrii w sposób znaczący zwiększa poziom zabezpieczeń w porównaniu do alternatywnych, tradycyjnych narzędzi. Jednakże jej powszechne zastosowanie wymaga regulacji prawnych, które z jednej strony pozwoliłyby organizacjom publicznym i prywatnym korzystać z tej metody jako instrumentu zapewniającego bezpieczeństwo, a z drugiej – ustanawiałyby minimalne standardy ochrony danych biometrycznych.
The article presents an analysis of new applications of biometrics in the field of security. There are two such key applications. Firstly, apart from documents such as IDs and passports, biometrics can be efficiently used as a physical access control tool in companies that play strategic functions in the public security system. Secondly, it can be applied in the e-banking industry as a customer identification and transaction authorization instrument. In both cases biometrics significantly increases the security level comparing to traditional alternatives. However, a common application of biometrics requires legal regulations that, on the one hand, will allow public and private organizations to use biometrics as a security instrument and, on the other hand, set minimal standards of biometric data protection.

Opis:
The idea of cancelable biometrics is widely used nowadays for user authentication. It is based on encrypted or intentionally-distorted templates. These templates can be used for user verification, while keeping the original user biometrics safe. Multiple biometric traits can be used to enhance the security level. These traits can be merged together for cancelable template generation. In this paper, a new system for cancelable template generation is presented depending on discrete cosine transform (DCT) merging and joint photographic experts group (JPEG) compression concepts. The DCT has an energy compaction property. The low-frequency quartile in the DCT domain maintains most of the image energy. Hence, the first quartile from each of the four biometrics for the same user is kept and other quartiles are removed. All kept coefficients from the four biometric images are concatenated to formulate a single template. The JPEG compression of this single template with a high compression ratio induces some intended distortion in the template. Hence, it can be used as a cancelable template for the user acquired from his four biometric traits. It can be changed according to the arrangement of biometric quartiles and the compression ratio used. The proposed system has been tested through merging of face, palmprint, iris, and fingerprint images. It achieves a high user verification accuracy of up to 100%. It is also robust in the presence of noise.

Opis:
This article is focused on the family of role-based trust management languages (RT). Trust management languages are a useful method of representing security credentials and policies in large distributed access control mechanisms. They provide sets of credentials that are assigned to individual roles performed by the specific entities. These credentials provide relevant information about security policies issued by trusted authorities and define user permissions. RT languages describe the individual entities and the roles that these entities play in a given environment. A set of credentials representing a given security policy defines which entity has the necessary rights to access a specific resource and which entity does not have such rights. This study presents the results of research focusing on the potential of the family of RT languages. Its purpose is to show how security policies may be applied more widely by applying an inference system, and then using the extensions of the credentials, by taking into account time-related information or the conditions imposed with regard to the validity of such credentials. Each of these extensions can be used jointly or separately, offering even a wider range of opportunities.

Opis:
Modern integrated information and telecommunication systems are upgraded on a continuous basis. Such systems contain both new and old components. The approaches to developing individual components of access control systems are different in the majority of cases. As a rule, modernization of outdated but efficient systems that have been operating without any failures for long periods of time is economically unfeasible. Such an approach requires that different subsystems function based on shared data. This necessitates the coordination of various access control systems in order to ensure proper information security levels. This article examines how joint functioning of various versions of access control systems deployed in IT and telecommunication spheres may be achieved at the stage of their modernization. Potential ways in which information flows may bypass the security policies of one of the access control systems concerned are determined. The authors discuss traditional access control models. For role-based and thematic access control models, specific hypotheses are formulated to comply with security policies when different versions of access control systems work together. The structure of the model assuming that different versions of access control systems operate jointly has been developed. Based on the model, the necessary and sufficient conditions are determined under which unauthorized information flows are prevented. The security theorem for the joint functioning of different versions of access control systems is presented and proved. The results of the study showed that the methodological basis for coordinating access control models applicable to information and telecommunication systems undergoing modernization consists in observing, separately, the equality of information flows between shared objects in each of the versions of the access control systems. The approaches developed in this article can be extended to combined access control systems.

Biometrics is the study of automated methods for uniquely recognizing humans based upon one or more intrinsic physical or behavioral traits. In information technology, a biometric authentication refers to technologies that measure and analyzes human physical and behavioral characteristics for authentication purposes. One of the most impressive examples of methods based on physical characteristics is facial recognition, which is the subject of this article. Biometric access control based on facial recognition system compare with other methods is not invasive, effective and easy in use that is why it was chosen. Human face is like a map with a lot of landmarks. Those special points make people exceptional. There are few main parts of the map which the program should identify: distance between eyes, width of nose, depth of eye sockets, cheekbones, mouth line and chin. After those measurements a person can be identified. The whole process of identification consists of five main steps: detection, alignment, normalization, representation and matching. The program was tested. Given results were satisfied. Non-braking development of IT section using biometrics will lead to the revolution of access control. In a few years people will not need a key, because they will already have one - the body.

Opis:
This paper presents novel mechanisms that effectively detect password file thefts and at the same time prevent uncovering passwords. The proposed mechanism uses delay between consecutive keystrokes of the password characters. In presented case, a user should not only enter his password correctly during the sign-up process, but also needs to introduce relatively large time gaps between certain password characters. The proposed novel approaches disguise stored passwords by adding a suffix value that helps in detecting password file theft at the first sign-in attempt by an adversary who steals and cracks the hashed password file. Any attempt to login using a real password without adding the time delays in the correct positions may considered as an impersonation attack, i.e. the password file has been stolen and cracked.

Opis:
Ciphertext policy attribute-based encryption (CPABE) is one of the efficient implementations of encrypted access control scheme for cloud computing. Though multiple implementations of CPABE exist, there are some issues that need to be addressed, including efficient revocation approach, decryption time, storage cost etc. In this paper, an efficient scheme that incorporates a hierarchical access structure, outsourced decryption, as well as user and attribute revocation is presented. The hierarchical access structure is utilized to encrypt multiple data using one common access structure and makes the encryption process more efficient. The outsourcing server is used to perform partial decryption, so that all heavy computations are performed by this server and less overhead is incurred by the data user. The proposed framework also integrates the evaluation of trustworthiness of data users and service providers to ensure trusted and encrypted access control procedures. The paper also presents an analysis of the time required for performing different operations. Simulation results show that the proposed scheme outperforms the existing approaches.

Opis:
All Database Management Systems used in the industry provide secure access to data at the server level. The level of security is influenced by technology, security model, password encryption method, password strength and others. The human factor – unreasonable behaviour of users – also has a significant impact on safety. Developers of database applications often implement their security policy by limiting the risk caused by users. This implementation has a disadvantage – it does not work outside of the application. A large number and variety of applications that work with the database server may then create a security gap. The paper presents the authors’ extensions of the functional features implemented in the Oracle database server, increasing the security of data access. The implemented methods of controlling the time of user access to data and limiting the use of serial and modular passwords are also discussed.

Opis:
Trust plays an important role in human life environments. That is why the researchers has been focusing on it for a long time. It allows us to delegate tasks and decisions to an appropriate person. In social sciences trust between humans was studied, but it also was analyzed in economic transactions. A lot of computer scientists from different areas, like security, semantic web, electronic commerce, social networks tried to transfer this concept to their domains. Trust is an essential factor in any kind of network, whether social or computer. Wireless sensor networks (WSN) are characterized by severely constrained resources, they have limited power supplies, low transmission bandwidth, small memory sizes and limited energy, therefore security techniques used in traditional wired networks cannot be adopted directly. Some effort has been expended in this fields, but the concept of trust is defined in slightly different ways by different researchers. In this paper we will show how the family of Role-based Trust management languages (RT) can be used in WSN. RT is used for representing security policies and credentials in decentralized, distributed access control systems. A credential provides information about the privileges of users and the security policies issued by one or more trusted authorities.
