Technology Brief:

Researchers at New Jersey Institute of Technology in the Department of Electrical and Computer Engineering have invented a novel solution that improves the communication efficiency of secret sharing schemes.


A secret sharing scheme is a method to distribute shares to parties such that only authorized subsets of parties can reconstruct the secret. The central problem is how to minimize the total amount of communication between the user and the parties when the user wants to reconstruct the secret by downloading information from a set of parties. Current secret sharing schemes are not efficient in terms of the communication overhead due to the paradigm of decoding from a minimum set of parties. The invention let the user to download from more (than the necessary number of) parties and therefore reduces the amount of communicated data. In addition, the proposed communication efficient secret sharing schemes also improve disk access complexity during decoding.
