From an arbitrary given channel code over a discrete or Gaussian
memoryless channel, we construct a wiretap code with the strong
security. Our construction can achieve the wiretap capacity under
mild assumptions. The key tool is the new privacy amplification
theorem bounding the eavesdropped information in terms of the Gallager
function. |
