The research was carried out and the development of an effective practical algorithm for the construction of system-wide parameters and keys for cryptographic transformations such as asymmetric ciphers and the key encapsulation protocol was performed in the paper. The experimental confirmation of the built-in system-wide parameters and keys of cryptographic transformations such as asymmetric cipher and the key encapsulation protocol of 6-7 stability levels based on transformations in the ring of polynomials over the finite fields is presented. Also in the work there are types of attacks that are possible with respect to the specified cryptographic transformations.
