1. A method comprises: encrypting, by a computing device of a dispersed storage network (DSN), a first data segment of a data object using a first encryption key to produce a first encrypted data segment; appending, by the computing device, the first encrypted data segment with a second encryption key to produce a first encrypted appended data segment; dispersed storage error encoding, by the computing device, the first encrypted appended data segment to produce a first set of error encoded data slices; encrypting, by the computing device, the first encryption key using the second encryption key to produce a first encryption key layer; encrypting, by the computing device, a second data segment of the data object using a third encryption key to produce a second encrypted data segment; appending, by the computing device, the second encrypted data segment with a fourth encryption key to produce a second encrypted appended data segment; dispersed storage error encoding, by the computing device, the second encrypted appended data segment to produce a second set of error encoded data slices; appending, by the computing device, the third encryption key with the first encryption key layer to produce a first appended encryption key layer; encrypting, by the computing device, the first appended encryption key layer using the fourth encryption key to produce a second encryption key layer; generating, by the computing device, a final encryption key layer in accordance with an encryption key layering scheme and the second encryption key layer; and dispersed storage error encoding, by the computing device, the final encryption key layer to produce a set of error encoded encryption key layer slices.
