Method and system for handling sensitive data in a content delivery network

摘要

Using cryptographic techniques, sensitive data is protected against disclosure in the event of a compromise of a content delivery network (CDN) edge infrastructure. These techniques obviate storage and/or transfer of such sensitive data, even with respect to payment transactions that are being authorized or otherwise enabled from CDN edge servers.

1. Apparatus, comprising:
a processor; computer memory storing computer program instructions executed by the processor to: receive over the first secure transport link a message that includes sensitive data; determine an identity of first and second issuing entities; parse the message to extract at least a portion of the sensitive data; apply to the portion of the sensitive data extracted (i) a first public key of a first issuing entity to generate a first value, and (ii) a second public key of a second issuing entity to generate a second value; for each of the first and second values generated, determine whether each respective value is associated with an identifier uniquely associated with the respective value; in response to determining that the first value is associated with a first identifier, retrieve a first token, and forward the message including the first token to a first management back-end over a second secure transport link; and in response to determining that the first value is associated with a second identifier, retrieve a second token, and forward the message including the second token to a second management back-end over the second secure transport link.
