Understanding ASC X9 TR-31 Key Blocks, X9.143, PCI Requirements (I32b)
Hardware Security Modules use keys to process payment transactions–which are protected in Key Blocks when outside the HSM. Key Blocks have received a lot of attention in the last few years. This talk takes you through the PCI requirements for Key Blocks from the speaker’s perspective–as a PCI-HSM certified vendor as well as the editor of ANSI X9.143, the new U.S. national standard based on ASC X9 TR-31. After covering PCI practical requirements they will walk through the interesting new features of ANSI X9.143, which help the HSM vendor as well as the client.
