Trusted terminal, dual-channel card, anti-cloning chip, chip fingerprint and anti-channel attack method

Abstract

The invention discloses a trusted terminal, a double-channel card, an anti-cloning chip, a chip fingerprint and a channel attack resistance method. The trusted terminal comprises a main control chip, a double-channel card slot, a channel isolation part and a communication interface; the double-channel card slot comprises a first channel connector and a second channel connector; the first channel connector is connected with the main control chip; the second channel connector is connected with the channel isolation part; the double-channel card slot is used for enabling the double-channel card to be inserted in. The trusted terminal and the double-channel card which are disclosed by the invention can replace an existing IC (Integrated Circuit) card to carry out migration and have the advantages of high safety, strong universality, low cost, easiness for implementation and the like. The key points for high safety are as follows: the existing bank IC card is easy to clone so as to easily generate the undistinguishable condition, and a payment password of the existing bank IC card is easy to intercept and capture; the double-channel card cannot be cloned, can avoid the undistinguishable condition and can effectively protect safety of the payment password.

Description

technical field [0001] The invention relates to the field of security technology, in particular to a trusted terminal, a dual-channel card, an anti-cloning chip, a chip fingerprint and an anti-channel attack method. Background technique [0002] Basic definition: channel refers to the signal transmission channel, including the transmission channel between terminals, the transmission channel between the same terminal chip and chip / chip and component / component and component, the data bus between the modules inside the chip, and Various signal paths inside a chip or module. A Trojan horse refers to a malicious program with the functions of eavesdropping, leaking, tampering, inserting, replaying, intercepting and forwarding. Chip fingerprint: similar to human fingerprints, each chip extracted inside the chip is different and unique information. Anti-cloning chip: For chips including chip fingerprint modules, manufacturers cannot produce completely identical anti-cloning chips....

Problems solved by technology

[0007] 2) Side-channel attack: Signals inherently have side-channel leakage during channel transmission and processing, that is to say, chips will be implanted with Trojan horses that leak side-channel information without exception during production.

[0017] The more important problem with bank IC cards is that the chip does not have anti-cloning capabilities, which will make the following two "indistinguishable" situations: i) A's IC card is unintentionally cloned, and the password is unintentionally intercepted (or the password card / password used card is also cloned), the attacker sends the cloned card and password to C for fraudulent swiping, and A claims for compensation; ii) B clones his own IC card, gives the cloned IC card and password to C to swipe the card, and then B makes a claim for compensation

Therefore, the existing terminals and chips cannot really achieve the security of "chip" and "password"
