Side-Channel Attack on Substitution Blocks
1 We describe a side-channel attack on a substitution block, which is usually implemented as a table lookup operation. In particular, we have investigated smartcard implementations...

Trust on Web Browser: Attack vs. Defense
This paper proposes a browser spoofing attack which can break the weakest link from the server to user, i.e., man-computerinterface, and hence defeat the whole security system of ...

Implementing Oblivious Transfer Using Collection of Dense Trapdoor Permutations
Abstract. Until recently, the existence of collection of trapdoor permutations (TDP) was believed (and claimed) to imply almost all of the major cryptographic primitives, including...

Rerandomizable and Replayable Adaptive Chosen Ciphertext Attack Secure Cryptosystems
Recently Canetti, Krawczyk and Nielsen defined the notion of replayable adaptive chosen ciphertext attack (RCCA) secure encryption. Essentially a cryptosystem that is RCCA secure ...

Computational Collapse of Quantum State with Application to Oblivious Transfer
Quantum 2-party cryptography differs from its classical counterpart in at least one important way: Given blak-box access to a perfect commitment scheme there exists a secure 1−2...

A Universally Composable Mix-Net
We show how to public-key obfuscate two commonly used shuffles: decryption shuffles which permute and decrypt ciphertexts, and re-encryption shuffles which permute and re-encrypt c...

Hierarchical Threshold Secret Sharing
We consider the problem of threshold secret sharing in groups with hierarchical structure. In such settings, the secret is shared among a group of participants that is partitioned ...

On the Notion of Pseudo-Free Groups
We explore the notion of a pseudo-free group, first introduced by Hohenberger [Hoh03], and provide an alternative stronger definition. We show that if Z∗ n is a pseudo-free abe...
