摘要

Digital signing of data in the Web-based IS is one of the most secure methods for guaranteeing the authenticity of data. Storage of user keys is particularly important for this methodology. The present development proposes a new algorithm for storage and usage of user keys for the database by the digital certificate of the client. The proposed methodology was designed for protection of data in a particular information system. One of the characteristics of this system is the great number of authorized users with rights for access and modification of various parts of data. With such systems it is extremely important to guarantee the authenticity of data stored in the system. Digital signing of data provides such guarantee of their authenticity.
