GenoGuard: Protecting Genomic Data against Brute-Force Attacks

Jean-Pierre Hubaux, Jacques Fellay, Erman Ayday, Zhicong Huang, Ari Juels

Secure storage of genomic data is of great and increasing importance. The scientific community's improving ability to interpret individuals' genetic materials and the growing size of genetic database populations have been aggravating the potential conseque ...

A Related-Key Attack against Multiple Encryption based on Fixed Points

Serge Vaudenay, Atefeh Mashatan, Asli Bay

In order to alleviate the burden of short keys, encrypting a multiple times has been proposed. In the multiple encryption mode, there may be encryptions under the same or different keys. There have been several attacks against this encryption mode. When tr ...

Related-Key Attack against Triple Encryption based on Fixed Points

Serge Vaudenay

Triple encryption was proposed to increase the security of single encryption when the key is too short. In the past, there have been several attacks in this encryption mode. When triple encryption is based on two keys, Merkle and Hellman proposed a subtle ...

Fast Software AES Encryption

Joppe Willem Bos, Dag Arne Osvik, Deian Stefan

This paper presents new software speed records for AES-128 encryption for architectures at both ends of the performance spectrum. On the one side we target the low-end 8-bit AVR rnicrocontrollers and 32-bit ARM microprocessors, while on the other side of t ...

Efficient Cache Attacks on AES, and Countermeasures

Dag Arne Osvik

We describe several software side-channel attacks based on inter-process leakage through the state of the CPU's memory cache. This leakage reveals memory access patterns, which can be used for cryptanalysis of cryptographic primitives that employ data-depe ...

Performance Analysis of 3-D Monolithic Integrated Circuits

Giovanni De Micheli, Vasileios Pavlidis, Shashi Kanth Bobba

3-D monolithic integration (3DMI), also termed as sequential integration, is a potential technology for future gigascale circuits. Since the device layers are processed in sequential order, the size of the vertical contacts is similar to traditional contac ...

On the Impossibility of Strong Encryption over \aleph_{0}

Serge Vaudenay

We give two impossibility results regarding strong encryption over an infinite enumerable domain. The first one relates to statistically secure one-time encryption. The second one relates to computationally secure encryption resisting adaptive chosen ciphe ...

Cryptanalysis of the full MMB Block Cipher

Jorge Nakahara, Yue Sun

The block cipher MMB was designed by Daemen, Govaerts and Vandewalle, in 1993, as an alternative to the IDEA block cipher. We exploit and describe unusual properties of the modular multiplication in ZZ232 −1 , which lead to a diﬀerential attack on the full ...
