The “Four Corners” model, also called the “Four Party Scheme”, is utilized in almost all standard card payment systems across the globe. Here, we talk about that model and explain what kind of hardware security module (HSM) is needed for each of its components involved in the cryptographic process.
EMV Personalization is a process used to get card data into cards, mobile phones, and wearables. The process includes a variety of complicated cryptographic tasks and activities, ranging from choosing proper cryptographic algorithms to authentication procedures. Ensuring all these steps are carried out accurately and securely is highly critical for card issuing and payments.
Here we explain why additional security mechanisms, beyond the mobile OS security features, are needed to protect mobile banking applications from malware and related threats.
As the use of mobile phones for mobile banking and payment applications increases, corresponding security threats are increasing as well. The majority of smart phones use only two operating systems (Android and iOS) and, therefore, they represent prey of choice for criminal groups and malevolent hackers.
In this article, we will explain some of the defense mechanisms and security techniques involved with protecting mobile banking applications.
Among all the various key block formats, the TR-34 format is undoubtedly one of the most sophisticated.
The TR-34 norm is an implementation of the X9.24-2 norm. It proposes a realistic and efficient way of exchanging symmetric keys using asymmetric cryptography. This is basically a certificate-based Remote Key Loading (RKL) protocol.
This article proposes a few answers to a series of frequently asked questions (FAQs) about key blocks and their use with PCI.
Merchants are one of the corners of the ‘four corner’ model in the payment world. In what follows, we will explain some of the security mechanisms for Merchants to prevent unauthorized transactions and payment card fraud.
An issuer is one of the corners in the ‘four corner’ model. An issuer is a financial organization (e.g. a bank) that produces payment cards and allows the cardholders to use them.
