The field of secret splitting algorithms has recently seen solutions based on using syntactic methods to create further information used as an additional component of the split secret. One of such solutions comprises linguistic threshold schemes which use context-free grammars to code the input string representing the shared secret. This study describes a general protocol for creating secret components using this approach. This solution allows the known, traditional secret sharing algorithms to be extended into algorithms executed in a hierarchical way. Such methods can then be used to split and manage information in various information structures that have linear characteristics or divisional dependencies.
