Practical attacks against WEP and WPA
Erik Tews,Martin Beck +1 more
TL;DR: In this article, the authors describe two attacks on IEEE 802.11 based wireless LANs: improved key recovery attack on WEP, which reduces the average number of packets an attacker has to intercept to recover the secret key, and dictionary attack when a weak pre-shared key is used.

Breaking 104 Bit WEP in less than 60 seconds
TL;DR: An active attack on the WEP protocol is demonstrated that is able to recover a 104-bit WEP key using less than 40,000 frames with a success probability of 50%.
Journal ArticleDOI
Efficiently Outsourcing Multiparty Computation Under Multiple Keys
TL;DR: This work proposes a novel technique based on additively homomorphic encryption that is efficient, requires no user interaction whatsoever (except for data upload and download), and allows evaluating any dynamically chosen function on inputs encrypted under different public keys.

Efficiently Outsourcing Multiparty Computation under Multiple Keys.
TL;DR: In this article, the authors proposed additively homomorphic encryption (AHE) for secure multiparty computation, which allows evaluating any dynamically chosen function on inputs encrypted under different public keys.

Revisiting SSL/TLS implementations: new Bleichenbacher side channels and attacks
TL;DR: Four new Bleichenbacher side channels are presented, and two of them provide the first timing-based BleichenBacher attacks on SSL/TLS described in the literature, with timing differences between 1 and 23 microseconds.
