    摘要: A method begins with a processing module obtaining encoded key slices from a plurality of user devices and decoding a threshold number of the encoded key slices utilizing a first error coding dispersal storage function to produce a key when the threshold number of the encoded key slices has been obtained. The method continues with the processing module receiving encoded data slices and decoding a threshold number of encoded data slices utilizing a second error coding dispersal storage function to produce encrypted data when the threshold number of the encoded data slices has been received. The method continues with the processing module decrypting the encrypted data utilizing the key and an encryption function to produce data.

    摘要: A method begins by a processing module obtaining an encoded data slice and an associated slice name. The method continues with the processing module determining a dispersed storage (DS) unit for storing the encoded data slice based on at least one of the encoded data slice and the associated slice name and estimating a performance level of the DS unit to produce an estimated DS unit performance level. The method continues with the processing module sending the encoded data slice to the DS unit for storage therein and when the estimated DS unit performance level compares unfavorably with a performance threshold, facilitating storage of the encoded data slice in temporary memory to produce a temporarily stored encoded data slice, wherein the temporarily stored encoded data slice is retrieved in response to a retrieval request when confirmation of the DS unit storing the encoded data slice has not been received.
