ter technology, data processing and telemunications. Adaptation of the information systems’ techniques for the needs of measurement systems created a new interdisciplinary field dealing with Distributed MeasurementControl Systems (DMCS). Elements of DMCS (nodes) are distributed territorially, connected via wired or wireless work and able to exchange information between each other. Currently the research in the area of DMCS is focused on the applicability issues and adapting of new information and munication technologies for such systems [8]. Nowadays, a very important issue in DMCS technology ensures the safety of munication. In many cases, the success of often costly experiments or missions and also the biological and economical security depends on the proper functioning of such systems. Due to the still growing integration with telemunications and general public puter works, the security of distributed measurement systems has been dramatically reduced. In many DMCS the information security of the work bees one of the major development problems. Information security issues are also very important (because of the specific openness of such systems, and ease of attack) in the wireless and mobile DMCS systems. Since the nodes of DMCS can be both socalled Measuring Servers, usually based on PCs with huge processor power, as well as mobile wireless sensors powered from battery, the existing disparity of calculation power makes another important issue for the development of mon methods, ensuring the safety of DMCS. Therefore there is an urgent need to develop proper methods and tools to ensure the safety and security of these systems [1, 8]. The software plays nowadays a huge role in measurement systems and very often determines their quality. The growing processors’ puting power and memory capacity allows for the development of more plex software. An important issue bees the creation of new methods and software tools for designing distributed measurement systems, and in particular lowcost and easyto use libraries and tools for designing software that provides secure exchange of information independently of used information and munication infrastructure. Existing software design tools dedicated for DMCS, integrated software environments such as LabVIEW, LabWindows/CVI, HPVEE, enable simple and flexible development process of applications, but among others do not include libraries for secure data exchange. The security problem was only slightly considered which has resulted in the introduction of certain access control mechanisms to certain parts of an application (front panels and their ponents) based on login and password identification system. But there is no use of cryptographic methods, and the information between nodes is sent explicitly, mostly as a plain text. Therefore, it seems necessary to develop a plete library of functions, programs and tools tailored to specific programming environments, which would give the application or system developer the opportunity to design and simulate secure and safe distributed measurement system in an easy and intuitive way. These additives should help to ensure safe transmission of data in any munication infrastructure and the creation of mechanisms for authentication and integrity of both measurement and control data. In the previous work, the authors have analyzed the LabVIEW environment capabilities for efficient implementation of cryptographic algorithms [1]. The next phase of the work, described in this paper, is to develop new mathematical tool for LabVIEW environment a Large Number library (also known as Big Integer or arbitrary length integer library). This library allows for the putation on numbers with arbitrary (within the limits of available memory) number of decimal digits, far exceeding the typical representation in puter systems (32 or 64bit). Large numbers are widely used in many popular cryptographic algorithms, including RSA, Rabin or ElGamal publickey encryption systems, used fo。
