Conclusions

Abstract

Almost every security issue in our day-to-day lives stems not from weaknesses in cryptographic algorithms, but the environment in which cryptographic algorithms are executed. There is a dire need for investment in a (perhaps global) infrastructure for realizing sufficiently trustworthy hardware modules, which can provide a safe environment for execution of cryptographic algorithms. As security protocols guarantee the existence of specific application-specific relationships between application-specific inputs and outputs, in order to ensure application-specific assurances, the trusted environment should have the capability to execute a possibly unlimited number of application-specific algorithms.
