Active networks are composed of special nodes (named Active Router) that are able to execute active code to offer the active services. This technology introduces some security threats that must be solved using a security architecture. We have developed a security architecture (ROSA) for an active network platform (SARA). Java has been used as programming language in order to provide portability, but it imposes some performance limitations. This paper analyses the penalty of using Java and proposes some mechanisms to improve the performance of cryptographic implementations in Java.application/pdfengAtribución-NoComercial-SinDerivadas 3.0 EspañaActive networksSecurityCryptographyJavaJNIconference outputTelecomunicacionesopen access
