Abstract
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.
