We make a new proposal about how to use in an effective way a CSPRBG (Computationally Secure Pseudo Random Bit Generator) for cryptographic purposes. We introduce the definitions of TCSPRBG (Typical CSPRBG) and SCSPRBG (Special CSPRBG). In particular the definition of SCSPRBG synthetizes in a simple way our proposal of how to modify a CSPRBG in order to achieve a higher throughput rate, while retaining some essential features of its computational security. We then summarize which should be, in our opinion, a "standard way" to use a CSPRBG for cryptographic purposes. We eventually present as an application, a particular SCSPRBG for which we can achieve throughput rates greater than 100 Mbits/sec on current mobile devices.
