| titleOfInvention | Method of generating a pseudo-random number in a portable electronic objects system and a system for carrying out the method |
| abstract | Method for generating a random number in a system comprising portable objects such as cards incorporating memory chips and microcircuits. A random number is generated by the processing circuits of the portable objects, taking into account a first parameter (PA1) constituted by the data from a field (RB) of the memory (MC) of the object, this data being modified on each random number request during a session, and a second parameter (PA2) constituted by data from another memory zone (13) of the object, this data being modified at least once during each session, and retained between two successive modifications from one session to the next. |
