Universally Composable Security with Local Adversariess centralized entities that control all parties that deviate from the protocol. While this centralized-adversary modeling suffices for capturing basic security properties such as secrecy of local inputs and correctness of outputs against coordinated attacks, it turns out to be inadequate for capturi

On the Strength Comparison of the ECDLP and the IFPeived much attention since smaller ECC key sizes provide the same security level as RSA. Although there are a lot of previous works that analyze the security of ECC and RSA, the comparison of strengths varies depending on analysis. The aim of this paper is once again to compare the security strength

New Attacks for Knapsack Based Cryptosystemse main observation is that the . property of the secret key sequence . used in the original MH construction is not necessary for the attack. More precisely, the attack is applicable as long as there are sufficiently many secret key elements . whose size is much smaller than the size of the secret mo

Multiple Differential Cryptanalysis Using , and ,, Statistics may not be as accurate as wished due to recent advances in this field. One of the main improvements to differential cryptanalysis is the use of many differentials to reduce the data complexity. In this paper we propose a general model for understanding multiple differential cryptanalysis and propos

History-Free Sequential Aggregate Signaturesusly to MACs we argue about new security definitions for such schemes and compare them to previous notions for history-dependent schemes. We finally give a construction based on the BLS signature scheme which satisfies our notion.

Decentralized Dynamic Broadcast Encryptiond as an extension to the subset-cover framework. It allows for efficient concrete instantiations, with parameter sizes that match those of the subset-cover constructions, while at the same time achieving the highest security level in the standard model under the DDH assumption.

Improved Secure Two-Party Computation via Information-Theoretic Garbled Circuitse-art GC, both in communication and computation, by a factor log., where . is a security parameter. In practical terms, already for today’s . ∈ {128,256} our (unoptimized) algorithm offers approximately a factor 2 communication improvement in the semi-honest model, and is only a factor ≈ 1.5 more costly in setting with covert client.
