Hybrid Multiple Key Spaces Schemes Using Unitals
摘要
There is considered a multiple key space distribution scheme characterized by a small amount of required key memory and resistance to compromise of a certain number of nodes due to the use of unitals for assigning keys to nodes and subsequent transformation into key spaces according to the Blom scheme, as well as the use of nodes corresponding to blocks of a certain parallel class of unital block design and commuting according to the projective plane scheme, as trusted centers.
