Mobile Terminal Security

The miniaturization of electronics and recent developments in biometric and screen technologies will permit a pervasive presence of embedded systems. This - and the inclusion of networking capabilities and IP addresses in many handheld devices - will foster the widespread deployment of personal mobile equipment.\smallskip This work attempts to overview these diverse aspects of mobile device security. We will describe mobile networks\u27 security (WLAN and WPAN security, GSM and 3GPP security) and address platform security issues such as bytecode verification for mobile equipment and protection against viruses and Trojan horses in mobile environment - with a concrete J2ME implementation example. Finally we will turn to hardware attacks and briefly survey the physical weaknesses that can be exploited to compromise mobile equipment.\smallski

Ongoing Research Areas in Symmetric Cryptography

This report is a deliverable for the ECRYPT European network of excellence in cryptology. It gives a brief summary of some of the research trends in symmetric cryptography at the time of writing. The following aspects of symmetric cryptography are investigated in this report: • the status of work with regards to different types of symmetric algorithms, including block ciphers, stream ciphers, hash functions and MAC algorithms (Section 1); • the recently proposed algebraic attacks on symmetric primitives (Section 2); • the design criteria for symmetric ciphers (Section 3); • the provable properties of symmetric primitives (Section 4); • the major industrial needs in the area of symmetric cryptography (Section 5)
