We give a construction of an adaptive garbled RAM scheme. In the adaptive setting, a client first garbles a ``large'' persistent database which is stored on a server. Next, the client can provide mult...
Garbled RAM, introduced by Lu and Ostrovsky (Eurocrypt 2013), provides a novel method to garble RAM (Random Access Machine) programs directly. It can be seen as a RAM analogue of Yao's garbled circuit...
The notion of garbled random-access machines (garbled RAMs) was introduced by Lu and Ostrovsky
(Eurocrypt 2013). It can be seen as an analogue of Yao’s garbled circuits, that allows a user to garble

In EUROCRYPT 2013, Lu and Ostrovsky proposed the notion of Garbled RAM (GRAM) programs.
These GRAM programs are analogous to the classic result of Yao’s garbled circuits: a large encrypted
memory ca...
Yao’s garbled circuit construction is a fundamental construction in cryptography and recent effi-
ciency optimizations have brought it much closer to practice. However these constructions work only f...
Garbled RAM, introduced by Lu and Ostrovsky, enables the task of garbling a RAM (Random Access
Machine) program directly, there by avoiding the inefficient process of first converting it into a circu...
We construct the first fully succinct garbling scheme for RAM programs, assuming the existence of
indistinguishability obfuscation for circuits and one-way functions. That is, the size, space require...
In 1982, Yao introduced a fundamental technique of “circuit garbling” that became a central
building block in cryptography. Recently, the question of garbling general random-access memory
(RAM) prog...
We show how to garble a large persistent database and then garble, one by one, a sequence of
adaptively and adversarially chosen RAM programs that query and modify the database in arbitrary
ways. St...
