# Oblivious Transfer where neither party learns the index of the message

In a traditional Oblivious Transfer setting, the sender has a list $(x_1, x_2, ... , x_n) \in G$ where $G$ is the chosen group. The receiver has $b \in \mathbb{N}$, such that engaging in the protocol the receiver is given $x_b$ and the sender does not learn $b$.

Presume I want a slightly different procedure, where the receiver gets a random $x_i$ and neither the sender nor receiver learn $i$.

Is there a name for protocols with this behavior?
