The intertwining of telecom, banking, and M2M/IoT produces a new degree of complexity. We hope our COMPRION glossary helps you to get a good overview of all the connected terms, technologies, and concepts.
Tamper-resistant platform (typically a one chip secure micro-controller) capable of securely hosting applications and their confidential and cryptographic data (for example, key management) in accordance with the rules and security requirements set forth by a set of well-identified trusted authorities.
There are three different form factors of secure elements: UICC, embedded SE, and micro-SD. Both the UICC and micro-SD are removable. Each form factor links to a different business implementation and satisfies a different market need.
Protocol that allows an application on an NFC-enabled device to exchange NFC Data Exchange Format (NDEF) messages with another NFC Forum device when operating in NFC Forum peer-to-peer mode. The protocol makes use of the Logical Link Control (LLC) protocol connection-oriented transport mode to provide a reliable data exchange.
Specification for a single-wire connection between the SIM card and an NFC chip in a cell phone. SWP is an interface between CLF and UICC. It is a contact-based protocol that is used for contactless communication. C6 pin of UICC is connected to CLF for SWP support. It is a bit-oriented full-duplex protocol which means that simultaneous transmission and reception are possible. CLF acts as a master and UICC as a slave. CLF provides the UICC with energy, a transmission clock, data, and signal for bus management. The data to be transmitted is represented by the binary states of voltage and current on the single wire.
Another word for chip card or ICC. It is any pocket-sized card with embedded integrated circuits. Smart cards are usually made of plastic. Smart cards can provide identification, authentication, data storage, and application processing. Smart cards may provide strong security authentication for single sign-on within large organizations.
Mobile internet access based on smart cards that is enabled by a USIM which is capable of supporting standard web technologies like HTML and HTTP. COMPRION supports the improvement of this technology by offering simulation of an SCWS application on a UICC based on:
Often abbreviated as ’spec’, refers to an explicit set of requirements to be satisfied by a material, design, product, or service.
In ISO/IEC 7816-3, it is assumed that the start bit begins with the first falling edge after a reset or after a bit sequence. If the bit following this edge has been identified by the bit sampling process as a low bit, it is indeed a start bit and the bit sequence following afterwards is evaluated. If the bit sampling results in a high bit, the next falling edge after the sampling time point is considered as the starting point of the next bit. A check is then performed to ascertain whether this is a start bit.
In ISO/IEC 7816-3, the stop bits are evaluated for protocol T=0 as follows: Bit sampling is performed in the time frame from 0.5 etu to 1.5 etu of the first two stop bits. An error will only be signaled if the bit sampling discovers a low bit and the transfer direction of this bit is not the same as the transfer direction of the byte.
A SIM circuit is embedded into a removable plastic card. This plastic card is called ’SIM card’ and can be transferred between different mobile devices. A SIM card follows certain smart card standards. SIM cards were first made the same size as a credit card (85.60 mm × 53.98 mm × 0.76 mm = 1FF (1st form factor)). The development of physically smaller mobile devices prompted the development of smaller SIM cards where the quantity of card surrounding the integrated circuit is reduced. As the SIM used to be the dominating application on these types of smart cards, even nowadays, the card (hardware) itself is often called SIM, too.
External interface that synchronizes COMPRION's contactless devices allowing synchronous monitoring of the complete NFC communication chain between a smart card and a contactless reader. Contact-based SWP signals and the contactless ISO/IEC 14443 interface signals are recorded in one single file with the same time base and are shown together in COMPRION test software.
