Implementation of Simplex Channels in the Blom's Keys Pre-Distribution Scheme
This is an incremental improvement for secure communication systems, addressing specific directional constraints in key pre-distribution.
The authors tackled the problem of key distribution in secure communication by modifying Blom's scheme to account for information stream direction, proposing an asymmetric exponential function that maintains key material volume.
In article the modification of the Blom's keys preliminary distribution scheme, considering the direction of information streams is suggested. For this modification it is necessary to use function from three variables. Function of formation of key materials will be the asymmetrical. The exponential form of this function which does not increase the volume of key materials is suggested.
