Security and the Class Verifier

View Flat

Summary: This article looks at the class verifier of the Java virtual machine (JVM). The class verifier enables untrusted code to be verified up front, rather than on the fly as the code is executed. This ability provides uninterrupted execution (the program can't "crash" uncontrollably) at a minimal cost in speed degradation.
