Up-to-date methods and means of data encryption guarantee reliable security (in particular, data confidentiality and integrity), but the development of cryptanalysis methods encourages the development and implementation of new, more efficient, cryptoalgorithms. In addition, the formation of new requirements for cryptographic methods and means is influenced by the development of modern information and communication technologies (LTE/5G/6G). With this in mind, in the paper well-known software modules of cryptographic data protection were analyzed, which are currently used in messengers and other applications. This analysis revealed the advantages, disadvantages and ways to improve (in particular, through the use of modern security procedures) modules of cryptographic data protection. A prototype was selected and the cryptographic information security module was improved. This module fixes information about the user ID, session ID, sending time, message length and serial number, as well as uses a new session key generation procedure for encryption. It allows to ensure the data confidentiality and integrity in information-communication systems and networks. To effectively use the advanced method, it is important to choose secure encryption and hashing methods, as well as secret key synchronization. Known cryptographic methods and tools secure against linear, differential, algebraic, quantum and other known types of cryptanalysis can be used there. Further work will focus on practical research of the advanced module for data cryptographic security using various methods of encryption and hashing, in particular those proposed by the authors in their previous research studies.
