Talk: non-contact IC card chip technology trends (1)

Non-contact IC card and IC card as an important form, in recent years also got very big development.

This article on non-contact IC card chip technology and the development trend of doing an analysis.

1. introduction

IC card since the 1970s have been since the birth of the great development, IC card has gradually entered including finance, communications, medical, public transit, identification of multiple applications, use the IC card is also increasing.

Non-contact IC card and IC card as an important form, in recent years also got very big development. This article on non-contact IC card chip technology and the development trend of doing an analysis.

2. non-contact IC card chip technology development trends

CPU card chip 1) replace the logic encryption card chip development trends

Currently the most common non-contact IC card is non-contact type logical cryptographic cards, IC cards due to their high performance and high price has been favored by the majority of users, and has been widely used in public transport, medical, campus card, access control, etc.

Due to the non-contact chip for logical cryptographic cards using stream ciphers, the key length is not very long (more typical of the password length is 48 bit Mifare), so logic encryption card chip and generally there is a security risk, there is the possibility of hackers to crack. In finance, identification, electronic passports, and so on that require higher levels of areas currently prefer using the embedded microprocessor for non-contact CPU card chip.

CPU card chip has a double safety mechanism, the first is the chip itself integrated encryption algorithm module, chip design companies typically will be proven most secure several encryption algorithms integrated into the chip, the more common security algorithms are RSA, 3-DES, etc.

Domestic chip design company also introduces has algorithms (SSF33, SCB2, SM2, SM3, etc.) to strengthen the security of the chip. Has algorithm is not public, so other than the algorithm has publicly algorithm of encryption algorithms has increased security. The second protection is specific to the CPU card chip COS (Card Operation System) system, you can set up for chip COS multiple independent of the password, key in the directory for storage of each directory key mutual independence, and firewall features (different directory key do not affect each other). While COS internal also established password maximum retry attempts to prevent malicious attacks. This shows that the non-contact CPU card than non-contact type logical cryptographic cards have better security.

In addition, the CPU card can realize the true meaning of "smart card", each application independently and controlled by their respective key management system.

Different applications can share a "wallet" and you can have a separate "purse". Service providers can use CPU cards for more flexible and effective management, the user can also use CPU cards multifunctional application needs. Since the CPU card chip than logic encryption card chips have more advantages in international markets on the CPU card chip market share more. According to the internationally renowned research institutions IDTechex RFID market statistics, 2007 global CPU card chip (including contact CPU card chip) shipments reached 33 million, it is expected that the 2008 CPU card chip shipments more than 38 million, and the logical cryptographic cards of shipments in 2007, less than 10 billion and year-downward trend.
