https://doi.org/10.1007/978-94-009-1365-3 We determine minimal supports for some ℤ.-linear codes. Finally, we extend a recently established link between the cryptographical problem of secret sharing and minimal supports to the case of rings. The resulting secret-sharing schemes have fully and partially authorized coalitions, which permits, e.g., hierarchical access to a common resource.
