Research of the application of the new cryptographic algorithms: applying the cipher algorithm O'zDSt1105:2009 for MS office document encryption

In countries where national cryptographic data protection algorithms are adopted, there is necessary to use these algorithms for cryptographic data protection. This article discusses the method of applying new cipher algorithms to encrypt Microsoft Office documents. The method of implementing document encryption in Microsoft Word 2016, which allows the protection of information from unauthorized access, is offered on the example of the cipher algorithm O'zDSt1105:2009 and the first hash algorithm O'zDSt1106:2009. This method allows applying the encryption other documents of the Microsoft Office products. A method is proposed to apply new cipher algorithms and hashing algorithms through the design and implementing of the next generation cryptographic provider, which provides an opportunity to improve the relative crypto stability of encrypted Microsoft Office documents using the O'zDSt1105:2009 cipher algorithm and the O'zDSt1106:2009 hashing algorithm.
