SIGNED SCRIPTS FOR SECURE ELEMENT CRYPTOGRAPHIC FUNCTIONS CUSTOMIZATION

摘要

The present invention relates to a method to customize cryptographic functions (LScr) using keys in a secure environment (SE) based on a secure scripting using certified domain specific language (DSL) having certified basic cryptographic primitives enforcing a set of given security rules and heuristics (R&H) used by a script development kit (SDK) dedicated to acquire a source script file (SScr) using the domain specific language, to transform the source script file (SScr) then including a signature and to filter non certification compliant source script, a script loader (ScrL) to load script files, to check signatures and to make resulting cryptographic functions (LScr) available in embedded software memory, said script loader (ScrL) sharing at least one signature cryptographic element (SK, EK) with the script development kit (SDK).
