In this work we investigate the problem of automating the development of adaptive chosen ciphertext attacks on systems that contain vulnerable format oracles. Unlike previous attempts, which simply au...
Quantum Chosen-Ciphertext Attacks against Feistel Ciphers
Feistel cipher Quantum chosen-ciphertext attacks Simon's algorithm
<
2018/12/19
Seminal results by Luby and Rackoff show that the 3-round Feistel cipher is secure against chosen-plaintext attacks (CPAs), and the 4-round version is secure against chosen-ciphertext attacks (CCAs). ...

Large-scale quantum computing is a significant threat to classical public-key cryptography. In strong “quantum access” security models, numerous symmetric-key cryptosystems are also vulnerable. We con...

We propose the first identity-based encryption (IBE) scheme that is (almost) tightly secure against chosen-ciphertext attacks. Our scheme is efficient, in the sense that its ciphertext overhead is onl...
Simulation-Based Selective Opening Security for Receivers under Chosen-Ciphertext Attacks

Security against selective opening attack (SOA) for receivers requires that in a multi-user setting, even if an adversary has access to all ciphertexts, and adaptively corrupts some fraction of the us...

We present a general construction of RSO security against chosen ciphertext attacks (RSO-CCA) by combining any RSO secure scheme against chosen plaintext attacks (RSO-CPA) with any regular CCA secure ...
A public key encryption scheme secure against key dependent chosen plaintext and adaptive chosen ciphertext attacks

2009/6/9
Recently, at Crypto 2008, Boneh, Halevi, Hamburg, and Ostrovsky (BHHO) solved the longstanding
open problem of "circular encryption," by presenting a public key encryption scheme
and proving that it...
ID-based Encryption Scheme Secure against Chosen Ciphertext Attacks

2009/3/9
ID-based encryption allows for a sender to encrypt a message
to an identity without access to a public key certificate. Based on the
bilinear pairing, Boneh and Franklin proposed the first practical...

In [2], Stanislav Bulygin presents a chosen-ciphertext attack against
certain instances of noncommutative polly cracker-type cryptosystems which
were proposed in [7] and [9]. In this article, we pre...
