We give the first positive results about instantiability of the widely implemented and standardized RSA-OAEP encryption scheme of Bellare and Rogaway (EUROCRYPT 1994) and variants under chosen-ciphert...
Quantum Security of the Fujisaki-Okamoto and OAEP Transforms
Quantum Random oracle Indistinguishability against chosen ciphertext attack
2016/1/27
In this paper, we present a hybrid encryption scheme that is chosen ciphertext secure
in the quantum random oracle model. Our scheme is a combination of an asymmetric and
a symmetric encryption sche...
Identification Based Encryption with RSA-OAEP. Using SEM and Without
IBE mRSA SEM RSA-IBE Classic RSA OAEP CPA
2012/6/14
In this article we show how we can integrate the RSA (RSA-OAEP) into the IBE. Our prove can be make with either Standard Model or Random Oracle. We firstly develop the basic ideas made in this directi...

We show that the widely deployed RSA-OAEP encryption scheme of Bellare and Rogaway (Eurocrypt 1994), which combines RSA with two rounds of an underlying Feistel network whose hash ({\em i.e.}, round) ...

Automatic Approach of Provable Security and its Application for OAEP+
cryptographic protocols probable security automatic security proof
2009/6/11
Probable security is an important criteria for analyzing the security of cryptographic protocols. However, writing and verifying proofs by hand are prone to errors. This paper introduces the game-base...
Recently Victor Shoup noted that there is a gap in the widely-believed security
result of OAEP against adaptive chosen-ciphertext attacks. Moreover,
he showed that, presumably, OAEP cannot be proven...
OAEP Reconsidered
OAEP insecure random oracle model
2009/4/17
The OAEP encryption scheme was introduced by Bellare and Rogaway at Eurocrypt
'94. It converts any trapdoor permutation scheme into a public-key encryption
scheme. OAEP is widely believed to provide...
OAEP++: A Very Simple Way to Apply OAEP to Deterministic OW-CPA Primitives
random oracle model provable security OAEP IND-CCA2 OW-CPA
2009/4/15
We prove in the random oracle model that OAEP++, which
was proposed by us at the rump session of Asiacrypt 2000, can generate
IND-CCA2 ciphers using deterministic OW-CPA cryptographic primitives.
N...
We introduce the OAEP++ encoding method, which is an adaptation
of the OAEP encoding method, replacing the last step of the
encoding operation with an application of a block cipher such as AES.
We ...
A Weak-Randomizer Attack on RSA-OAEP with e = 3
Weak-Randomizer Attack RSA-OAEP Coppersmith's heuristic algorithm
2009/2/13
Coppersmith's heuristic algorithm for finding small roots of bivariate modular equations
can be applied against low-exponent RSA-OAEP if its randomizer is weak. An adversary that
knows the randomize...
Firstly, we demonstrate a pathological hash function choice that makes RSA-OAEP insecure.
This shows that at least some security property is necessary for the hash functions used in RSAOAEP.
