Existence versus exploitation: the opacity of backdoors and backbones
Boolean formulas often have what are known as hidden structures. We study the complexity of whether such structures (of certain sizes) exist in a...

U.S. Security Policy: The Dual-Use Regulation of Cryptography and its Effects on Surveillance
Cryptography has become ubiquitous in communication technology and is considered a necessary part of information security. However, the regulation to...

Embedding asymmetric backdoors into the RSA key generator
This article describes the class of asymmetric backdoors in the RSA key generator. The algorithms are based on the classical Anderson’s backdoor, but...
-
Mathematical Foundation for Classical and Modern Cryptography
The design of public-key cyphers prevents knowledge of the encryption key from revealing the identity of the decryption key. Making advantage of a...

Blockchain-based immunization against kleptographic attacks
Adversarial implementations of cryptographic primitives called kleptographic attacks cause the leakage of secret information. Subliminal channel...

How to Backdoor (Classic) McEliece and How to Guard Against Backdoors
We show how to backdoor the McEliece cryptosystem such that a backdoored public key is indistinguishable from a usual public key, but allows to...

Detection of non-trivial preservable quotient spaces in S-Box(es)
Substitution Box (S-Box) is employed in block ciphers to ensure non-linearity. An n -bit bijective S-Box is a member of the Symmetric Group

Specifying a principle of cryptographic justice as a response to the problem of going dark
Over the past decade, the Five Eyes Intelligence community has argued cryptosystems with end-to-end encryption (E2EE) are disrupting the acquisition...

The MALICIOUS Framework: Embedding Backdoors into Tweakable Block Ciphers
Inserting backdoors in encryption algorithms has long seemed like a very interesting, yet difficult problem. Most attempts have been unsuccessful for...

On the Possibility of a Backdoor in the Micali-Schnorr Generator
In this paper, we study both the implications and potential impact of backdoored parameters for two RSA-based pseudorandom number generators: the...
