# Questions tagged [fault-attack]

Attacks using errors injected at runtime into an implementation of cryptographic algorithms to cause misbehavior that leak information about keys or (plaintext) data, instead of (or additional to) using cryptographic weaknesses. The countermeasures against such attacks also belong here.

### Statistical (innefective) Fault Attacks on DES

I read this paper: Exploiting Ineffective Fault Inductions on Symmetric Cryptography. I was wondering if the same idea is applicable for DES. I know both algorithms are symmetric but the idea is not ...

### Fault attack on RSA-CRT

I am trying to understand fault attack on RSA-CRT, and I found some example, which I don't know how to solve it. I know public modulus $N$, public exponent $e$, a value of faulty signature (where ...

### AES Fault Attack

Induce random fault (non-zero) error in one byte before MixColumns in Round 9 I get last round key with 32 bit (4 bytes) missing (Missing are bytes 1, 8, 11, 14) How can I recover these key bytes ...
I am trying to understand the Boneh-DeMillo-Lipton fault attack on RSA CRT signature. Suppose that we sign a message $m$ with RSA-CRT : $d_p = d \bmod (p-1)$ and $d_q = d \bmod (q-1)$ \$s_p = h(m)^{...
