A secret protection method operative on a user's device with a group of servers includes concealing a secret on the user's device with the user's password, the concealing not involving any of the servers, storing the output of the concealing on the device and reconstructing the secret from a newly received password and the stored output in conjunction with a subset of the group of servers, wherein the reconstructing is minimally affected by intermittent network connection problems and attacks that interfere with the communication between the user's device and the subset of servers, The reconstructing includes performing an enhanced PPSS (Password Protected Secret Sharing) reconstruction protocol between the user's device and the subset of servers and receiving the results of throttling performed by each of the subset of servers. |
