Security of Cryptosystems Based on Class Groups of Imaginary Quadratic Orders
Abstract. In this work we investigate the difficulty of the discrete logarithm problem in class groups of imaginary quadratic orders. In particular, we discuss several strategies t...

The Security of Triple Encryption and a Framework for Code-Based Game-Playing Proofs
We show that, in the ideal-cipher model, triple encryption (the cascade of three independently-keyed blockciphers) is more secure than single or double encryption, thereby resolvin...

A Hybrid Lattice-Reduction and Meet-in-the-Middle Attack Against NTRU
To date the NTRUEncrypt security parameters have been based on the existence of two types of attack: a meet-in-the-middle attack due to Odlyzko, and a conservative extrapolation of...

Existence Theorems and Approximation Algorithms for Generalized Network Security Games
—Aspnes et al [2] introduced an innovative game for modeling the containment of the spread of viruses and worms (security breaches) in a network. In this model, nodes choose to i...
