摘要：
This paper presents a (k, n) threshold scheme for sharing a secret. The scheme is based on some geometric properties. Only k (k less than or equal to n) shadows can recover the secret; while any k -1 or fewer shadows cannot obtain any information about the secret. Our scheme is an ideal secret sharing scheme. We also give a practical algorithm to solve the problem of dividing the secret into n shadows efficiently.
