Kerl uses SHA-3 Keccak at its core, which is a binary hashing algorithm. This means that the trinary 'trits' which IOTA normally operates on are converted to bits before being absorbed by Keccak, whose output is converted back from bits to trits after being squeezed out.
This extra radix conversion step is clearly suboptimal in terms of performance, so IOTA'...
In their official statement, the IOTA team stated:
"With Coordinator IOTA's security depends on one-wayness of
Curl-P, without Coordinator the security depends on collision
However, before the collision nonresistance of Curl-P was identified and published by DCI, these Curl-P properties were kept secret. For this reason, in the beginning ...
There is a reclaim tool built into the IOTA Light Wallet since version 2.5.2.
Just download the wallet and
click on Tools > Reclaim tool.
enter your old seed
enter your new seed
now you the Hash of your "Proof Transaction" will be displayed
Once the transaction is confirmed (reattach if necessary), the IOTA foundation knows that you are ...
Make sure you are upgraded to the newest IOTA wallet. If your balance is zero that means your wallet is connecting. Generate a new receive address and attach it to the tangle and wait a few minutes. If your balance is still zero, generate another receive address and attach it to the tangle and wait. If you have made several transactions using your wallet ...
PearlDiver computes 64 hashes at once. Those hardcoded values make the hashes be distinct by initializing the fragment not affected by the incrementing routine to values which are distinct.
An example for 3 hashes:
First we have:
After the first increment we get:
After the second increment we get:
Curl-P is not use for signing transaction, therefore collisions in Curl-P is not relevant.
For question 1:
Eve can try to do it, but the probability to achieve this in reasonable time is extremely low.
For question 2:
Any bit change in signed data (the amount, the address,...) completely change the signature. It is not easier to brut-force an almost ...
Yes, but the increased security is more of a side-effect of the employment of specialized chips. The JINN chips are believed to allow even the most lightweight of IoT devices to become full nodes, because they will contain ASICs that compute the IOTA hash function very quickly and with negligible energy consumption.
The reason this improves the security of ...
