| Summary | 0005446: auditor should count number of coins seen, not just their value | ||||
| Description | ... in order to do denomination key revocation correctly. In particular, only counting the value seen allows the adversary to only deposit a small amount of each forged coin, and then use the emergency recovery protocol (once 0005445 is implemented) to make a large profit. | ||||
| Tags | No tags attached. | ||||
| related to | 0005445 | closed | Christian Grothoff | emergency payback protocol should support refreshed coins |
| count_known_coins() now exists in exchangedb. num_issued was added to the 'struct DenominationSummary' in taler-auditor (and auditordb). What is missing is the logic to check that the two are (in)consistent and to extend the reporting logic accordingly. | |
