BUILDING OF A GENERALIZED QUALITY ASSESSMENT CRITERION CRYPTOGRAPHIC CODE SEQUENCES USED IN SECURE WIRELESS COMMUNICATION SYSTEMS

The analysis of statistical methods for assessing the cryptographic strength of code sequences used in secure wireless communication systems was carried out. The analysis showed that a universal quality assessment indicator (QAI) for assessing the cryptographic strength of code sequences was not proposed in the well-known works. It is noted that it is advisable to form a QAI complex for assessing the cryptographic resistance of code sequences using statistical methods. The QAIs previously described in the literature are to be included in this set. The formed QAI complex, according to the authors, makes it possible to more accurately assess the cryptographic resistance of code sequences used in secure wireless communication systems. To evaluate the cryptographic resistance of code sequences and to serve as a generalized quality criterion, a single tuple has been developed based on the QAI complex. It is noted that a tuple is not explicitly represented in known papers. The authors have modified the original tuple, taking into account the QAIs, responsible for reliability. The need to pay attention to the QAI complex is revealed in the use of cryptographic code sequences in secure wireless communication systems. The generalized quality assessment criterion will improve the accuracy of assessing the cryptographic resistance of code sequences used in secure wireless communication systems.
