The symmetric encryption session key generation protocol based on the Shamir secret sharing scheme and the Blom key predistribution scheme is proposed. Predistribution of key materials through secure channels is used. Key calculation is based on symmetric polynomials from three variables. Key calculation is based on threshold scheme (3,4). The basic protocol for two participants was considered. A scheme for an arbitrary number of users has been summarized.
