In this work we study linear secret sharing schemes for s-t connectivity in directed graphs. In such schemes the parties are edges of a complete directed graph, and a set of partie...

In a (r, n)-threshold secret sharing scheme, no group of (r - 1) colluding members can recover the secret value s. However, the number of colluders is likely to increase over time...
