HPE Security in Payment Systems
by The Nilson Report
When Hewlett-Packard split into two companies last year, storage, servers, and software became Hewlett Packard Enterprise (HPE). HPE’s Data Security business has four segments that impact payment systems. All deal with the encryption and tokenization of data either through hardware security modules (HSM) or software. HSMs are vaults that hold encryption keys. They are installed behind firewalls at data centers and connect to card networks, HSMs perform multiple functions triggered by a discrete command for each function. Sending minimal information in a command and receiving minimal information in response is a built-in security feature. That model of communication is used when verifying a payment card’s CVV number, a chip card’s ARQC for tokenization and 3D Secure, and when PINs are sent to card issuers from ATMs and POS terminals.
