There are two approaches to define Plaintext Awareness (PA). The first one is a classical approach to define the PA security and is used to define the PA security of the random oracle model. This approach enables us to define the PA-ness simply, but no one know whether we can define the standard model PA security based on this approach. In contrast, the second approach is a current approach to define the PA security. It enables us to define the standard model PA security formally, but it is more elaborate than the overwhelming-based approach. In this paper, we aim to clarify relations between the two approaches. We define the standard model PA security based on the first approach. Then we show that, under a very weak condition, it is equivalent to the known definition of the standard model PA security based on the second approach.
