Distributed File System | prof. Giovanni Chiola | ![]() |
Files can be added/deleted/modified by the owner. | ||
In principle nobody else should modify data, but this property is difficult to guarantee in a distributed system, where some of the components might be outside physical control. | ||
If someone else modifies data the integrity check must fail, so that one can tell whether data is original or not. | ||
Digital signatures can be used for integrity check on remote servers. | ||
