Retailer Crutchfield Corp. has decided to migrate away from encryption in favor of an alternative security technology known as tokenization. Tokenization is a process by which the primary account number (PAN) is replaced with a surrogate value called a token. It eliminates the need to go through an encryption-key rotation process, an insider says. The latest version of the Payment Card Industry standard, which any business processing payment cards must follow, has some changes in it related to how to store an encrypted hash of a credit card.”]
