Cryptographic Tamper Evidence

Cryptographic processors : applications and attacks survey

The combination of cryptographic tools and tamper-resistant mechanisms appeared first in military applications to secure communication links using tamper-resistant cipher machines. The spread of ATM networks brought the technology into the commercial mainstream. During the last years, the use of embedded cryptographic processors has spread from low-cost cryptoprocessors, such as smart cards use...

Tamper-resistant storage techniques for multimedia systems

Tamper-resistant storage techniques provide varying degrees of authenticity and integrity for data. This paper surveys five implemented tamper-resistant storage systems that use encryption, cryptographic hashes, digital signatures and error-correction primitives to provide varying levels of data protection. Five key evaluation points for such systems are: (1) authenticity guarantees, (2) integr...

A proposal of architectural elements for implementing secure software download service in software defined radio

In order to obtain an appropriate, high level of security, a number of architectural elements for secure downloading of software to a software defined radio (SDR) terminal have been pointed out. They include four different cryptographic techniques and employment of tamper resistant hardware. The cryptographic techniques employed are: (a) a secret key encryption technique; (b) a public key encry...
