It is the most important issue that the restrictive security policy and correct concurrency control is guaranteed. This paper considers the security of heterogeneous system with replicated data. The existed read-from relationship in the existed serializability is improper. So, we define secure read-from relationship and propose secure one-copy quasi-serializability by utilizing this relationship and display some examples. The proposed secure one-copy quasi-serializability is very proper for global transactions in that this serializability doesn’t violate security autonomy and prevents covert channel between global transactions.
