<p>In a method for distributing keys among a number of secure devices, the secure devices are divided into sets (A, B, C, D, E), each set having a plurality of subsets (a, b, c, d, e). Each subset comprises two or more secure devices having the same key which is unique for this subset. Each secure device is a member of a number of sets (A, B, C, D, E) such that two or more secure devices which are a member of a subset, are not a member of the same subset in another set.</p> |
