I am proud to announce the availability of our newest white paper, Tokenization vs. Encryption: Options for Compliance. The paper was written to close some gaps in our existing tokenization research coverage. I believe it is particularly important for two reasons. First, I was unable to find a critical examination of tokenization’s suitability for compliance. There are many possible applications of tokenization, but some of the claimed uses are not practical. Second, I wanted to dispel the myth that tokenization is a replacement technology for encryption, when in fact it’s a complimentary solution that – in some cases – makes regulatory compliance easier.
While I was writing the paper, the PCI council did not officially accept tokenization. As of August 12, 2011, the Council does offer guidance (if not full acceptance) on using tokenization as a suitable control for payment data. However, the guidance casts doubt on the suitability of hashing and format preserving encryption as methods to improve security and reduce the scope of an audit – which is consistent with this paper. Please review the PCI official announcement (PDF) for additional information.
The paper discusses the use of tokenization for payment data, personal information, and health records. This paper was written to address questions regarding the business applicability of tokenization, and is thus less technical than most of our research papers. I hope you enjoy reading it as much as I enjoyed writing it.
A special thanks to Prime Factors for sponsoring this research!
