A mean-field theory is developed for the recently proposed normal to superconducting vortex-glass transition. Using techniques developed to study the critical dynamics of spin glasses, we calculate the mean-field vortex-glass boundary {ital T}{sub {ital g}}({ital H}), and find that the dynamic critical exponent {ital z}=4 in mean-field theory. In addition, we find that the fluctuation conductivity in the vicinity of the transition has the form {sigma}{similar to}{xi}{sup (2{minus}{ital d}+{ital z})}, in agreement with recent scaling theories of the transition. The extension of these results beyond the mean-field regime is also discussed.
