Part 3 [ISO/IEC (E)] defines the initialization and anticollision protocols Note that ISO/IEC is a Contacted Integrated Circuit Card standard. INTERNATIONAL. STANDARD. ISO/IEC. Second edition. Identification ISO’s member body in the country of the requester. ISO copyright . The ISO/IEC describes how to select (“activate”) a single card. This card activation procedure is generally independent of the number.

Practical standards do practical implications. Post as a guest Ios. ISO anti-collision protocol is not correct Ask Question. But nevertheless it is not correct and the general director of the company I am working for will definitely come to look at what we are doing with two such cards in his wallet. There are usually some patterns like one vendor has some prefix and then prefix of card type – So it looks to me more like somebody had bad day than calculated trough decision.
I know it is very low probability 1: Also generation of UIDs is usually not made in Crypographically friendly way e.

I’ve been recently rewriting ISO anti-collision loop and found out that it is actually not correctly defined in the standard. Cryptography depends on an attacker not, by sheer luck, finding the right key on the first try; mechanical engineering is all “oh all these iron atoms are aranged in a neat metal grid, so the probability of a crystal fracture going through the whole steel beam supporting this skyscraper is really really small”.

The Innovatron company had working microprocessor 14443-3, so their technology was integrated as type B in the standard.
This answer talks about competing technologies brought forward by two different companies: Obviously, no hash is free of collisions, as long as the hash is shorter than the hashed data — but the probability of something isk changing the hashed data to false data with the same hash is so small, it can be neglected in practice. Some limitations quickly occurred: Am I right or did I miss something?
This problem existed in the version of the standard and was corrected in Amendment 1 in by oso the clause:. Sign up using Facebook.

I don’t like that you can easily fabricate this one – and it is not defined what to do in that case. Email Required, but never shown. I do agree, this is a bad thing tm to be in a standard. I don’t fully understand it. Or even detect that it happend. I’d like to understand why the ISO standard describes two types of interfaces, type A and type B. The probability that noise occurs that disrupts any communication is probably much higher!
I would expect though I did not check that this is also io case for the version of the standard. Home Questions Tags Users Unanswered.
Could you re-phrase this sentence: This separation is not relevant anymore since isi can have type A or type B memory or microprocessor cards, and we ended up with two competing technologies in the same standard.
Nowhere in the iso standard is written that uid3 cant be 88 only uid0 cant be
