A Security Enhancement Scheme for Wireless Packet Communications Using Secret Sharing and Precoding

Abstract (in Japanese) (See Japanese page) 
(in English) A secret sharing is a method in which the source information is divided into n shares and the source data is reconstructed from any k shares
but no knowledge of the source information is not revealed from k-1 shares.
This algorithm is called (k, n) threshold scheme.
In this study, we propose a security scheme for wireless packet communications.
The encryption key for packet information is set to the secret information,
and the secret information is divided into n shares,
and each share is located in the packet header.
The base-station transmits the packets to the target terminal using eigen-mode transmission based on precoding.
The transmission scheme realizes the receiving condition for the target terminal to receive more than k shares without error and to perfectly recover the secret information.
And the scheme also realizes the receiving condition for the eavesdropper terminal to receive less than k-1 shares without error and to recover no secret information.
Furthermore, we propose a protection scheme using secret sharing based on systematic Reed-Solomon codes,
which realizes the advantageous condition for the target terminal to recover the secret information.
Computer simulations show the validity of the proposed scheme.
