The data block is the same size as the key modulus. Generation of RSA signatures or RSA encryption first typically requires formatting the data to be signed or encrypted into a PKCS #1 Signature (Type 1) or Encryption (Type 2) data block. The product P*Q below is calculated to verify that P*Q = Modulus using class methods. The sample key-data below shows typical prime numbers P, Q, the Modulus and Exponent displayed as big-endian ordered byte arrays followed by the corresponding decimal integer number. Random selection of Modulus, E and D starts by random selection of two large prime numbers. D is usually chosen to be about the same size as the modulus (~128 bytes). The “private key” is usually described as a number pair consisting of the same key Modulus and a private exponent D. However, on boxes with virtual machines, this attack may be used by one VM to steal private keys from another VM” “Thus in practice, there are easier ways to access the private keys than to mount this side-channel attack.
This may seem like overkill since the attacker already has access to the machine, but where this gets interesting is with the use of VMs. The attack allows an attacker to extract the secret crypto key from a system by analyzing the pattern of memory utilization or the electromagnetic outputs of the device that are emitted during the decryption process.

The leak is significant enough for full recovery of RSA-1024 as well as 13% of RSA-2048 bit private keys.įor the 元 Cache Side-Channel Attack to work the attacker has to be able to run arbitrary software on the hardware where the private RSA key is used.

We show how to extend the Heninger-Shacham algorithm for partial key reconstruction to make use of this information and obtain a very efficient full key recovery for RSA-1024.”

“The pattern of squarings and multiplications in left-to-right sliding windows leaks significantly more information about the exponent than right-to-left. The vulnerability described is found in and with the use of the sliding window method more specifically the left-to-right sliding window method. A team of researchers, from Technical University of Eindhoven, the University of Illinois, the University of Pennsylvania, the University of Maryland, and the University of Adelaide, have released a white paper entitled ‘Sliding right into disaster: Left-to-right sliding windows leak,’ describing the vulnerability CVE-2017-7526 associated with Libgcrypt cryptographic library found by utilizing the local FLUSH+RELOAD side-channel attack.
