Onion Ring ORAM: Efficient Constant Bandwidth Oblivious RAM from (Leveled) TFHE
Homomorphic Encryption Oblivious RAM
2019/6/24
Oblivious RAM (ORAM) is a cryptographic primitive that allows a client to hide access pattern to its data encrypted and stored at a remote server. Traditionally, ORAM algorithms assume the server acts...
Optimal Oblivious Priority Queues and Offline Oblivious RAM
Oblivious RAM Oblivious Priority Queue
2019/3/4
In this work, we present the first asymptotically optimal oblivious priority queue, which matches the lower bound of Jacob, Larsen, and Nielsen (SODA'19). Our construction is conceptually simple, stat...
Quantum cryptanalysis in the RAM model: Claw-finding attacks on SIKE
quantum cryptanalysis SIDH
2019/2/27
We introduce models of computation that enable direct comparisons between classical and quantum algorithms. Incorporating previous work on quantum computation and error correction, we justify the use ...
Sub-logarithmic Distributed Oblivious RAM with Small Block Size
Oblivious RAM Multi-Server Setting Secure Computation
2019/1/26
Oblivious RAM (ORAM) is a cryptographic primitive that allows a client to securely execute RAM programs over data that is stored in an untrusted server. Distributed Oblivious RAM is a variant of ORAM,...
Multi-Party Oblivious RAM based on Function Secret Sharing and Replicated Secret Sharing Arithmetic
cryptographic protocols RAM
2019/1/2
In this work, we study the problem of constructing oblivious RAM for secure multi-party computation to obliviously access memory at private locations during secure computation. We build on recent two-...
OptORAMa: Optimal Oblivious RAM
Oblivious RAM ORAM
2018/11/9
Oblivious RAM (ORAM), first introduced in the ground-breaking work of Goldreich and Ostrovsky (STOC '87 and J. ACM '96) is a technique for provably obfuscating programs' access patterns, such that the...
Is there an Oblivious RAM Lower Bound for Online Reads?
Oblivious RAM Lower Bounds Locally Decodable Codes
2018/6/25
Oblivious RAM (ORAM), introduced by Goldreich and Ostrovsky (JACM 1996), can be used to read and write to memory in a way that hides which locations are being accessed. The best known ORAM schemes hav...
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...
An Oblivious RAM (ORAM) introduced by Goldreich and Ostrovsky [JACM'96] is a (possibly randomized) RAM, for which the memory access pattern reveals no information about the operations performed. The m...
PanORAMa: Oblivious RAM with Logarithmic Overhead
Oblivious RAM Oblivious Shuffle Oblivious Hash Table
2018/5/2
the input has a certain level of entropy. We combine these two primitives to improve the shuffle time in our hierarchical ORAM construction by avoiding heavy oblivious shuffles and leveraging entropy ...
We show that PRAMs can be obliviously simulated with perfect security, incurring only O(logNloglogN) blowup in parallel runtime, O(log3N) blowup in total work, and O(1) blowup in space relative to the...
In this work, we present a new approach to constructing Oblivious RAM (ORAM). Somewhat surprisingly, and despite the large amount of research interest that ORAM has received, all existing ORAM constru...
Oblivious RAM is a well-known cryptographic primitive to hide data access patterns. However, the best known ORAM schemes require a logarithmic computation time in the general case which makes it infea...
Efficient Maliciously Secure Multiparty Computation for RAM
Multiparty computation oblivious RAM garbled circuits
2017/10/10
A crucial issue, that mostly affects the performance of actively secure computation of RAM programs, is the task of reading/writing from/to memory in a private and authenticated manner. Previous works...

OPRAM PRAM
2017/9/13
Oblivious Parallel RAM (OPRAM), first proposed by Boyle, Chung, and Pass, is the natural parallel extension of Oblivious RAM (ORAM). OPRAM provides a powerful cryptographic building block for hiding t...
