15:17 [Pub][ePrint] An Attack on a Fully Homomorphic Encryption Scheme, by Hu Yupu, Wang Fenghe

  In this paper we present an attack on a fully homomorphic encryption scheme on PKC2010.

We construct a modi¯ed secret key, a modi¯ed decryption algorithm and a subset of the ciphertext

space. When the ciphertext is from the subset, we can correctly decrypt it by our modi¯ed secret key

and modi¯ed decryption algorithm. We also discuss when our modi¯ed decryption algorithm is e±cient,

and when the subset is not negligible.



15:17 [Pub][ePrint] Aggregating CL-Signatures Revisited: Extended Functionality and Better Efficiency, by Kwangsu Lee and Dong Hoon Lee and Moti Yung

  Aggregate signature is public-key signature that allows anyone to aggregate different signatures generated by different signers on different messages into a short aggregate signature. Although aggregate signatures have many applications like secure routing protocols and software module authentications, it is not easy to devise a suitable aggregate signature scheme that satisfies the conditions of real applications such that the size of public keys should be short, the size of aggregate signatures should be short, and the aggregate signing and aggregate verification should be efficient.

In this paper, we propose two aggregate signature schemes based on the Camenisch-Lysyanskaya signature scheme that sufficiently satisfy the conditions of real applications. At first, we construct an efficient sequential aggregate signature scheme and prove its security under the LRSW assumption without random oracles. The proposed scheme has the shortest size of public keys among the sequential aggregate signature schemes and very short size of aggregate signatures. Additionally, the aggregate verification of this scheme is very efficient since it only requires constant number of pairing operations and $l$ number of exponentiations where $l$ is the number of signers in an aggregate signature. Next, we construct an efficient synchronized aggregate signature scheme and prove its security under the LRSW assumption in the random oracle model. The proposed scheme has very short size of public keys and the shortest size of aggregate signatures among the synchronized aggregate signature schemes. The signing and aggregate verification is also very efficient since these requires constant number of pairing operations and $l$ number of exponentiations.

Furthermore, a signer of our aggregate signature schemes can use two mode of aggregation ``sequential\'\' and ``synchronized\'\' at the same time just using the same private key and the public key since the private keys and the public keys of two schemes are the same.

07:01 [Job][Update] Tenure track Assistant Professor, Digital Security, Radboud University Nijmegen

  The Digital Security group at the Radboud University Nijmegen has a

vacancy for a full-time assistant professorship (Universitair Docent

UD in Dutch).

General information

Research in the group covers a range of topics including correctess

and security of software, smartcards and RFID, design and analysis of

security protocols, applied crypto, privacy and anonimity, quantum

logic and computing. Members of the group are also active in the

broader societal issues surrounding security & privacy, and regulary

carry out commercial contract research to apply and inspire high

quality academic research.

The group runs a joint Master programme in Computer Security in

collaboration with the universities of Twente and Eindhoven, named the

Kerckhoffs Institute (www.kerckhoffs-institute.org). In Nijmegen the

Institute for Computing and Information Sciences runs Bachelor and

Master courses in Computer Science (Informatica) and Information

Science (Informatiekunde).

For this position we are looking for the best candidate in the broader

field of security, who can be a good addition to the group and has

good synergy with ongoing research in the group, who is a team player,

and who can teach computer security to a broad range of students.
