Access to smart card EMV data

Access to smart card data at the operating system level Obviously, all efforts to ensure the physical protection of the smart card will be in vain if the OS access control system is vulnerable. Access control is performed at the level of data structures, which are regulated by the international standard ISO 4. The main unit of information storage is a file. The file can be a structureless array of data or consist of records. Records can be of fixed or variable length. Depending on the organization of access to records, linear and cyclic files...

Smart Card Key Exchange operations for EMV Software

The distribution of keys is the most important process in the management of the keys. When using a symmetric cryptosystem, the two parties entering into an information exchange must first agree on a secret session key, that is, a key for encrypting all messages transmitted during the exchange. This key must be known to everyone else and periodically updated at the same time, both the sender and the recipient. The process of agreeing on a session key is also called key exchange, or key distribution. The PC/SC compatibility specification...

Crypto Interface for EMV Software

The main purpose of using smart cards in general-purpose computer systems is to provide cryptographic services to support common security infrastructures. In particular, the smart card is the best place to store the private key (from the public/private key pair), which is used for authentication in the public key infrastructure. A smart card is also a secure computing platform and the best place to perform a digital signature operation using a private key. Currently, there are two main cryptographic modules that provide application-level...

Smart card support architectures

The main goal of the architecture and specification of the interaction of smart cards with chips and personal computer systems PC/SC (Interoperability Specification for ICC and Personal Computer Systems) is to enable independent product development by reader manufacturers and smart card manufacturers, while ensuring that the results of their efforts will work together seamlessly. The PC/SC specification has developed a number of requirements for the compatibility of microprocessor cards and smart card readers: Cards and readers must comply...

Types of smart cards for EMV Software

Philips Seminiconductor Mifare Contactless Smart Cards An important place among the manufacturers of integrated circuits and smart cards is occupied by Philips Semiconductor. This company has developed a technology under the brand name Mifare, designed to create industry-standard contactless smart cards. Contactless cards are characterized by the absence of electromechanical contact with the device that receives and processes information from the card. Contactless smart cards belong to the group of passive cards that do not have batteries,...

Activating and deactivating EMV application

Activating the smart card EMV application is the final operation in the smart card manufacturing process. It involves setting checkboxes in memory that prohibit any further changes to this memory area, except for changes that are performed under the direct control of this application. These actions are an integral part of the security process. This is usually the last act before the process of transferring the smart card to its owner, and in some cases, activation may actually be performed after the card has passed into the owner’s...

Smart Card Personalization

Personalization of the card is a necessary step in preparing the card for its transfer to the owner. The term “personalization” in the broadest sense of the word means that all the data that is intended for a specific person or a specific card is entered into the smart card. The personalization procedure involves writing various information to the chip’s memory. It is also accompanied by a PIN code written to the card, which the owner can then use to confirm the card’s authenticity. According to the method of...

Features of the production of smart card cases

Contactless smart cards use a wireless communication mechanism between the card and the reader. The contactless card contains a built-in chip, without requiring a contact pad on its front surface. Instead, a winding is built into the card body as an antenna. The energy in the form of electromagnetic radiation is transmitted by the reader antenna and received by the card antenna. The resulting energy is small, but sufficient to power the integrated chip in the card. For the relatively low frequencies used for most modern contactless smart...

EMV Software development of smart card

The design of the chip and the software development of smart card According to ISO 10202-1, the first phase of the smart card lifecycle can be divided into two parts. The first of these parts covers the process of semiconductor manufacturing of the microcontroller and the generation of the smart card operating system, while the second part is devoted to the entire production technology of the card body. The production of the microcontroller chip and the generation of the smart card operating system are associated with the following...
