| Title: | Construction of a Secret Sharing Scheme with Multiple Extra Functionalities |
| Timeframe: | 09.2003 - 04.2004 |
| Supervisor: | Joel Friedman |
| Abstract: | In many circumstances, secret sharing has to provide more
flexibility and functionality than the fundamental (t,n) threshold schemes. The requirements for
different extra functionalities of a secret sharing scheme are often contradictory to each other,
which makes construction of a scheme with several additional features a challenge. We will introduce a basic threshold secret sharing scheme and will incrementally add several extra functionalities to it. Then we will critically analyze the strengths and weaknesses introduced into the scheme by each of these features. The added extra functionalities will allow to renew and recover shares, and to enroll/disenroll shareholders. We will discuss a method for upgrading the threshold access structure of a scheme to a general access structure. |
