Abstract
An encryption key may be fragmented into n encryption key fragments such that k<n fragments are sufficient for reconstructing the encryption key. The encryption key fragments may be distributed across data stores located within first and second geographic regions. For example, at least k of the encryption key fragments may be distributed across data stores realized at N different availability zones within the first geographic region such that less than k of the encryption key fragments are distributed to each of the N availability zones within the first geographic region. Similarly, at least k of the encryption key fragments may be distributed across data stores realized at M different availability zones within the second geographic region such that less than k of the encryption key fragments are distributed to each of the M availability zones within the second geographic region.
