The Enhanced Fuzzy Bit generator (EFBG): A Cryptographically Secure Pseudorandom Bit Generator

An enhanced version of the FBG (Fuzzy Bit Generator), recently introduced by the authors, is presented in this paper. The enhancement is such as to increase the security level of the FBG. The Enhanced- FBG (EFBG) is tested against the NIST statistical test suite as well as the TestUO1 statistical testing package to verify the high level of randomness of the generated output bit stream. In addition, the output stream is also tested against the Diehard package. A comparison with other cryptographic secure generators is also presented to show that this new generator is of comparable performance.
