On the Security of Long-Lived Archiving Systems Based on the Evidence Record Syntax ERS by proving ERS secure. This is done in a model presented by Canetti et al. that these authors used to establish the long-term security of the Content Integrity Service (CIS). CIS achieves the same goals as ERS but is much less efficient. We also discuss the model of Canetti et al. and propose new directions of research.

Countermeasures Mitigation for Designing Rich Shell Code in Java Cardparticulary dynamic bound checking of the code segment. We propose here a new attack path for performing a type confusion that leads to a Java based self modifying code. Then, to mitigate this new attack an improvement to the previous countermeasure is proposed.

A Dynamic Attribute-Based Authentication Scheme an ABA scheme based on down-to-top built attribute trees or dynamic attribute trees, which can change when attribute requirements change. Therefore, the proposed dynamic ABA scheme is more efficient in a dynamic environment by avoiding regenerating the whole attribute tree each time attribute requirements change.
