PT IBM Corp. announced Thursday a secure method for digitally scrambling and signing data that it claims will take half the time of today's fastest techniques. By combining the two steps, this security algorithm will help accelerate e-business.
Encryption is a way of scrambling data so that only users with the right key can read the data.
Authentication is a way to sign a file so that anyone who reads the file can be assured of its origin. IBM hopes the combination technique will be used in securing Internet communications and data-storage networks. It's a factor of two. A factor of two improvement is not that important. I agree Joe.
