METHOD AND DEVICE FOR PROCESSING AND DISTRIBUTING SOFTWARE COMPONENT

摘要

PROBLEM TO BE SOLVED: To make an idea in software to be more safe by inspecting a software component and decoding a part obtained by detecting a compiled part and ciphering the part when it exists. SOLUTION: A Java compiler takes out a source code and converts it into a byte code (S1). A post Java compiling processing is applied to a class file and a 'compiled method' attribute is set (S2A). A post Java ciphering processing is applied to the class file and several methods are ciphered (S2B). The changed class file is taken out from a server or a storage device and it is cache-stored (S3). A JVM(Java virtual machine) class loader verifies the byte code by inspecting a syntax agasint a Java language specification and prepares the class object from the changed class file and solves a symbol in the class object (S4, 5 and 6).
