P2PE vs. E2EE: What’s the Best Payment Security Option for Governments?

If end-to-end encryption (E2EE) and point-to-point encryption (P2PE) sound like they could be the same thing, you’re not wrong. Technically speaking, P2PE is a specific type of E2EE, and the objective in both uses is to secure cardholder data from the time it’s captured until it reaches its intended destination.
However, only one of these methods offers significant time savings and cost benefits to the government agencies that use them. Read on to understand the differences between E2EE and P2PE and why choosing P2PE could be in your department’s best interest.
What Is P2PE?
As the ongoing threat of data breaches continues to menace government agencies of all sizes , securing cardholder data remains a top priority. In recent years, P2PE has become the gold standard for credit card payment security compliance.
Here’s why: Payment card industry (PCI)-validated P2PE is a set of standards defined by the PCI Security Standards Council (SSC) that outlines a comprehensive set of best practices spanning the device supply chain, encryption key loading, configuration, encryption and application security.
The P2PE process creates a secure connection between devices, or components within devices, which prevents possible sensitive data from being exposed at any point while moving across a network. It effectively removes cardholder data from an agency’s environment, providing better protection for the cardholder.
How Does P2PE Work?
P2PE encrypts cardholder data immediately upon receiving a card payment. It sends this encrypted code directly from the payment terminal to the payment processing system, where the information gets decrypted using a secure key.
Since the decryption takes place entirely in the payment processor, the government entity never sees any of the cardholder’s information. If hackers manage to intercept the data while it’s in transit, they will not be able to read the data because only the processor possesses the key—there’s no chance someone can steal the key from the government agency or any other transactional party.
PCI P2PE Compliance Requirements
P2PE reduces the likelihood of PCI compliance breaches by directly connecting the payment terminal to the processing system—and correspondingly drops the number of self-assessment questionnaire questions from over 300 to around 30. This function means your department can raise the bar on security without also increasing the compliance audit burden.
Some other key compliance requirements include:
The data must be encrypted at the payment terminal.
