Descriptions
PolarSSL versions prior to v1.1 use the HAVEGE random number generation algorithm. At its heart, this uses timing information based on the processor's high resolution timer (the RDTSC instruction). This instruction can be virtualized, and some virtual machine hosts have chosen to disable this instruction, returning 0s or predictable results.
PolarSSL versiones anteriores a v1.1, usan el algoritmo de generación de números aleatorios HAVEGE. En su esencia, éste usa información de tiempo basada en el temporizador de alta resolución del procesador (la instrucción RDTSC). Esta instrucción puede ser virtualizada, y algunos hosts de máquinas virtuales han optado por deshabilitar esta instrucción, devolviendo 0s o resultados predecibles
