Cross-Group Secret Sharing 0.1.0

Cloud datastore services have been essential to access your data from anywhere. However, they still have risks of data leakage since each cloud service occasionally becomes a target from malicious attackers and data loss since hard-wares of each cloud service occasionally are broken. To solve this problem, we’ve introduced cross-group secret sharing scheme, which distributes a secret into servers from several could providers so that the secret can be reconstructed even if some of servers are attacked or become out-of-service. This software provides both a Go library and command line tools implementing the cross-group secret sharing scheme.
