  Detecting malicious portable document format files with data mining techniques
  
  Annotation:
  
  The necessity to timely detect malicious documents which cause malicious code execution on users' computers due to exploitation of vulnerabilities is very actual issue of information security. At this time this threat is actively used in order to arrange creating botnets, stealing personal assets of users and other criminal acts with the help of so-called exploit kits and the threat seems to be used in future as well. The paper’s focus is on the issues of static structural analysis of malicious PDF (Portable Document Format) files and development of approach to detect such files by using Data Mining techniques.

  Annotation:
  
  The opportunity to model an intrusion into a computer system using the imbalance of the observation process is considered in this article. Well-known estimates of trusted bracket for the intrusion time contain parameters depended on type of distributions before and after intrusion. Taking into account the lack of such information it is recommended to use algorithms barely depended on the distribution character and to research the efficiency of intrusion estimate using experimental methods.

  Annotation:
  
  Finding the key of symmetric cipher takes solving of polynomial equations. Complexity of solving process can be reduced if exact or approximate basis of ideal of substitution is defined by short polynomials. Accuracy of short basis can be increased using affine change of variables. Two methods for solving system of Boolean equations are proposed.

  Efficiency evaluation of botnets’ disinfection and removal
  
  Annotation:
  
  Nowadays there is lack of efficiency evaluation methods, which will allow to compare efficiency of defense and intrusion tools, in particular, botnets. Set of efficiency evaluation metrics is proposed. These metrics take into consideration network nature of modern defense and intrusion tools and allow to obtain a numerical estimate for factors, significant for defense or intrusion efficiency. Therefore, these metrics allow to make a conclusion about result of the battle between networks of benign and malignant agents, and conclusion about local or global area network protection.

  Finite-state model of adaptive behavior of multi-agent system, countering distributed computer threats in internet
  
  Annotation:
  
  Nowadays multi-agent systems, used either for implementing distributed security threats, or for protecting computer systems against distributed threats in Internet, maintain agents’ graph connectivity by maintaining excessive number of links, or don’t maintain connectivity in aggressive environment at all. Finite-state model of multi-agent system adaptive behavior is proposed. Proposed model is based on using d-regular graph of agents in connection with methods for maintaining network connectivity, which allow to provide functional efficiency of the system in aggressive environment.

  About a possibility of a hardware implemented GOST cipher breaking
  
  Annotation:
  
  We prove that there is a possibility to find the secret key from tamper resistant chip that provides encryption by algorithm GOST-28147-89. In order to solve this problem it is performed a side attack on power consumption. In a comparison with a simple power analysis it is performed the so called differential power analysis (DPA) that is tolerant to such protection technique as noising and shielding. We present an algorithm of key calculation given cipher text and estimate the number of operations needed to break all cipher. We remark that GOST cipher is more easy breakable by this attack rather than DES cipher. This means that module 232 addition that is implemented by GOST gives nothing advantages against DPA in comparison with a module 2 addition implemented by DES.

Proposed model of high-speed parallel network traffic processing on a multiprocessor cluster mathematically describes processes of load-balancing on clusters, network traffic classification and evaluation of its characteristics, which allows to increase in efficiency of network traffic's data processing.

  Analysis of hidden field equations cryptosystem over the odd-characteristic fields
  
  Annotation:
  
  Some results on cryptanalysis of Hidden Field Equations (HFE) cryptosystem over the odd-characteristic fields are presented. Using of odd-char HFE schemes reduces key generation, encryption and decryption time. Possible attacks are analyzed. Recommendations for HFE parameters choice are provided.

  Approach to search and elimination of duplicated inconsistent information at integration of data in the distributed automated systems of critical appointment
  
  Annotation:
  
  The procedures eliminating possible ambiguity, inconsistency and discrepancy of data in the distributed automated systems of critical appointment are considered and are mathematically proved. The method and a technique of control and search of the duplicated data for relational model are described respectively. Application of potential key attributes for an assessment of identity of objects in the distributed information automated system is offered. Values of a resultant matrix of similarity of potential key attributes are thus used.
