Abstract:
1. A method comprises: receiving, in response to a data segment access request, a decode threshold number of encoded data slices, wherein a data segment of data is encoded using a dispersed storage error coding function to produce a set of encoded data slices and wherein the decode threshold number of encoded data slices is a subset of the set of encoded data slices; determining whether to evoke a trust verification function after receiving the decode threshold number of encoded data slices; when the trust verification function is to be evoked, selecting one or more encoded data slices of the set of encoded data slices for trust verification to produce one or more selected encoded data slices; sending, to a trusted source, a request to receive the one or more selected encoded data slices; and when the one or more selected encoded data slices are received from the trusted source, determining that a trusted set of encoded data slices is available based on the decode threshold number of encoded data slices and the received one or more selected encoded data slices.
