A Study and Selection of Cryptographic Standards on the basis of Text Mining

This paper discusses the problems of application and choice of cryptographic standards taking into account user requirements and preferences. User profiles are created by means of the ontology apparatus. On the basis of user profiles and document features an appropriate set of documents is formed, the elements of which are then arranged according to the degree of compliance to user requirements. Various filtration methods, such as collaborative filtering, content analysis and filtering, as well as hybrid methods combining both approaches, are used. Thus, a recommender system for choosing cryptographic standards and algorithms is built. If there are several user selection criteria, it is reasonable to apply an integral index of object's relevance to user preferences. This index is defined as the weighed sum of the particular indices.
