Implicit Key-Stretching Security of Encryption Schemes
When keys are small or parts thereof leak, key-recovery attacks on symmetric-key primitives still pose a plausible threat. Key stretching is one well-known means to throttle potential adversaries, where stretc...

New Second Preimage Attacks on Dithered Hash Functions with Low Memory Complexity
Dithered hash functions were proposed by Rivest as a method to mitigate second preimage attacks on Merkle-Damgård hash functions. Despite that, second preimage attacks against dithered hash functions were prop...

Security on Your Hand: Secure Filesystems with a “Non-cryptographic” JAVA-Ring
In this paper we present the first implementation of highspeed filesystem encryption with a slow JAVA card. Using new “Remotely Keyed Protocols” designed by Lucks and Weis we can use the highly tamper-resistan...
