The paper reviews the paradigm of information security management, which involves the system configuration fixing, security evaluation of the system state, and system adaptation to the discovered security faults through feed-back control over security settings. The sample using the discussed technique is presented for UNIX-like systems. This technique and the control system based on it allow a procedure of security adaptation to be automated and thus considerably simplified. It forms a fundament for a new class of self- adapting security systems.

In the past ten years theory and technology of information security become more durable and always ready to resist to new threats. Today total damage of all system, due to gap on a security system, mostly depends on a user and his knowledge. Thereby than environment is more various then defense is stronger and then threats are more complex. But what will happen if environment has been changed? Environment mandatory will be cardinally changed. To make sure about it enough to look at continuously speed up growth of functional possibilities of the Internet: e-mail, sites, big portals, social networks and so on. And growth isn't going to stop. It is known that new possibilities on the some stage of their development result in qualitative change of environment. To solve security problems in new environment we may be needed in a new theoretical base. In this article we try to research the forming process of self-learning procedures in the World Wide Web. Of course today these procedures are forming by people. But in our opinion we should think about future security problems exactly today.

In the paper we consider new approach of software safety based on syntax-driven control for security. The notion "regularization of a grammar" is presented. CF grammar in a regular form (CFR-grammar) supplied with extended set of operations in regular expressions in the right hand side of rules is discussed. The scheme of CFR grammar regularization has been shown. — Bibl. 7 items.

Elliptic curves in Hesse form admit more suitable arithmetic than ones in Weierstrass form. But elliptic curve cryptosystems usually use Weierstrass form. It is known that both those forms are birationally equivalent. Birational equivalence is partially determined and it is relatively hard to compute. We prove that elliptic curves in Hesse form and in Weierstrass form are linearly isomorhic over initial field or its small extension and this equivalence is easy to compute. If cardinality of finite field q є 5 (mod 6) and Frobenius trace T є 0 (mod 3), then equivalence is defined over initial field with high probability. This linear equivalence allows multiplying of an elliptic curve point in Weierstrass form by passing to Hessian curve, computing in this curve and passing back. This speeds up the rate about 1,35 times.

We consider oblivious transfer protocol based on noisy channel. We carry out detailed analysis of protocol and it's rate dependence on requirements for given parameters. The modified protocol using interactive hashing for test the receiver's adherence to the protocol is presented which results in increasing protocol rate.

Given the significant dangers of Large Hadron Collider (LHC) operations, access control to the accelerator controls system is required. Role-Based Access Control (RBAC) was designed in order to protect the equipment from accidental and unauthorized access. This paper describes a new mathematical model of protection the distributed control system, based on role-based access control concept. It also contains the overview of authorization, the main component of the system.

This article concerns security aspects of buildings control and automation systems development. Nowadays RFID technology is often used in automation systems. In most cases RFID solutions are installed in airports, stadiums, distributor centers and factories. This makes human life highly dependant on security aspects on the innovative technology. Unfortunately the RFID technology is not as safe to computer viruses attacks as most believe it is. In this article new protocol is presented that proves to be safe and effective to prevent most common attacks on RFID technology.

Ciphers y = C(x, k) and ² = ‚(±, ¤) are isomorphic if there exists invertible computable in both directions map y « ², x « ±, k « ¤. Cipher is vulnerable if and only if isomorphic cipher is vulnerable. Instead of computing the key of a cipher it is sufficient to find suitable isomorphic cipher and compute its key. If j is arbitrary substitution and T is round substitution, its conjugate “ = jTj-1 is cipher isomorphism. Conjugate substitutions have the same cycle type. Conjugation can be composed with affine maps.
Application this method to AES gives affine conjugate substitution. Images of XOR with round key and diffusion map become non-linear. But they possess differentials and linear sums of high probability (8-12 times more then corresponding values of original S-box).
Finite binary mappings, ciphers, substitution differential.
