GBD Threshold Cryptography with an Application to RSA Key Recovery
[chapter]
2005
Lecture Notes in Computer Science
Preserved Fulltext
We also show an application of GBD threshold cryptography to RSA key recovery. ...
Finally, we point out two open problems in the RSA key recovery application. Verifiable Secret Sharing (VSS) scheme. See, for example, [Ped91] for ElGamal and [Sho00] for RSA. ...
We develop both GBD threshold decryption and GBD threshold key generation, and we consider finally an application to key recovery for the RSA cryptosystem. ...

These findings suggest that training practices for the development of aerobic components may improve also RSA. ...
After at least 48 hours, subjects performed an RSA test consisting of 10 × 20-m sprints interspersed with 20 seconds of active recovery, to determine the mean sprint time (RSAmean), the best sprint time ...
The aerobic energy system plays a key role in the return to homeostasis during the rest intervals of repeated sprints [6] . ...

In this paper we show an attack on this proposed proactive RSA scheme, in which an admissible threshold of malicious group members can completely recover the group RSA secret key in the course of the lifetime ...
Our attack stems from the fact that the threshold signature protocol which is a part of this proactive RSA scheme leaks some seemingly innocuous information about the secret signature key. ...
For larger values of e, the results of [3, 1] on the RSA key security with partial key exposure imply the following speed-ups in our RSA key recovery attack: If e meets the above criteria, the number ...

Furthermore, we also demonstrate that one round is sufficient for WSS when n > 4t, and that VSS can be achieved in 1 + " amortized rounds (for any " > 0) when n > 3t. ...
Threshold RSA cryptosystems are in use today, for example, the root CA key for MasterCard/VISA's Secure Electronic Transaction system is protected via a threshold RSA scheme [20] . ...
