In this paper, we propose a new
data encryption algorithm based on symmetric encryption technique.
<p>However, it said, merchants can use "Remote Key Injection services to upgrade the terminals if those services meet all aspects of the PCI [Payment Card Industry] Pin Security Requirements."<p>MasterCard's guidance around RKI comes at a time when merchants are under a deadline to upgrade their POS terminals to support Triple
Data Encryption Algorithm (TDES) standards.
The X9.42-2001 standard defines the secure establishment of cryptographic data for the keying of symmetrically keyed algorithms (e.g., Triple
Data Encryption Algorithm [TDEA]).
