Read-abortion (RA) based synchronization protocols to prevent illegal information flow
We propose RA-RBS and RA-OBS protocols. More than half of read operations are illegal without information flow control. No illegal information flow occur but some transactions are aborted in the protocols. The abortion ratio in the RA-OBS protocol is smaller than the RA-RBS protocol.
