Abstract (in Japanese) (See Japanese page) 
(in English) Secret sharing is a method in which the source information is divided into n shares and the source information 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 and is implemented by using Reed-Solomon(RS) coding.
In this study, we propose applications of (k,n) threshold secret sharing scheme implemented by systematic RS coding in which there exist arbitrary decided shares. Assuming that some user groups have secret informations and each secret information is protected by the secret sharing, a scheme which accesses to each secret information by the share commonly used with the groups is proposed in one application.
An analytical evaluation of the information protection of the wireless packet transmission based on the secret sharing scheme and the physical layer security is shown in the other application.
