This note proposes a method of space efficient secret sharing in which k secrets are mapped into n shares (n>=k) of the same size. ...
Since, n can be chosen to be equal to k, the method is space efficient. This method may be compared with conventional secret sharing schemes that divide a single secret into n shares. ...
Conclusions We have presented a space efficient secret sharing scheme. ...
