Накратко на български
Криптографската сигурност на безжичните сензорни мрежи, използвани например за охрана на граници, се анализира в този проект. Това е важно, защото стандартните методи за защита изразходват твърде много енергия и не са подходящи за малките устройства.

Final Activity Report Summary - CRYPTOSENSORS (Cryptographic security of wireless sensor networks)
This project concerned the applications of cryptography in the area of the wireless sensor networks (WSNs). WSNs are a new technology that can be used in building monitoring, burglar alarms, military applications, border control, etc. WSNs consist of a large number of intelligent nodes which are low-cost, low-power and small. Because of these properties a special care must be taken in the design of the protocols for such networks. Namely, one has to constrain the number of processor cycles and the number of radio-transmitted bits (since this costs energy), and one often cannot assume that the nodes do not leak any information about its state (in other words: they are not leakage-resilient). Because of these limitations many standard cryptographic protocols cannot be used in WSNs. This is especially true about the protocols based on the public-key cryptography (which is often too energy consuming). For example, the classical (public-key-based) methods for the key distribution cannot be used in WSNs. In this project we were particularly interested in the active security of sensor networks, i.e. security in a model where the adversary not only eavesdrops, but also actively disturbs the communication. The work performed by us is as follows. First, we gave a formal analysis of the active security of the existing key-distribution schemes for the sensor networks, and we provided a comparison between them. We concluded that the best scheme in this context is the one based on the method of Blom (1984). Second, we proposed a new method for secure aggregation in the sensor networks, which has increased resiliency against the active attacks. Third, we proposed a new, formal model, for increasing leakage-resiliency of cryptographic protocols, and implemented some basic cryptographic primitives (secret-sharing, stream cipher) in this model. This method is based on so-called Bounded-Retrieval Model, where the adversary is allowed to retrieve any information about the internal state of the machine, as long as the total length of the retrieved data is bounded

Цел на проекта
Wireless Sensor Networks (WSNs) are a new technology that may soon revolutionize several aspects of our life. WSNs consist of a big number of cheap sensor nodes that are connected with wireless links. Their aim is to jointly provide global information a bout some territory (basing on the local data). We are going to apply novel methods of cryptography in order to enhance the security of WSNs. The applicant is an expert in the former field, while the host research group consists of experts in the latter. Investigations of the cryptographic security of WSNs started very recently (3--4 years ago). We want to do it differently, and better. We plan to utilize those cryptographic methods that were not yet used in this context (or their use started very recently).In particular we will use the methods related to the Secure Multiparty Computations (MPC). Thus, our project has a truly multidisciplinary character. We plan to concentrate on the following problems in WSNs: secure routing, secure data aggregation and secure key establishment. These problems are topics of active research in several scientific institutes around the world. Some researchers have very recently observed that the MPC methods may be applied here, but nobody investigated it deeply.The added value of the project includes the following.(1) We believe that combining the expertise in cryptography with the knowledge of WSNs will have a synergizing effect and we expect to obtain interesting and nontrivial results.(2) The applicant will receive training in the areas related to the applications of cryptography (so far, he was specializing in the theoretical aspects of this field).(3) After the project is finished, the fellow will bring the acquired knowledge back to his university, where currently no research on WSNs is conducted.
