More on Correcting Errors in RSA Private Keys: Breaking CRT-RSA with Low Weight Decryption Exponents

Several schemes have been proposed towards the fast encryption and decryption in RSA and its variants. One popular idea is to use integers having low Hamming weight in the preparation of the decryption exponents. This is to reduce the multiplication effort in the square and multiply method in the exponentiation routine, both in encryption and decryption. In this paper we show that such schemes ...

Reconstructing RSA Private Keys from Random Key Bits

We show that an RSA private key with small public exponent can be efficiently recovered given a 0.27 fraction of its bits at random. An important application of this work is to the “cold boot” attacks of Halderman et al. We make new observations about the structure of RSA keys that allow our algorithm to make use of the redundant information in the typical storage format of an RSA private key. ...

A New Attack on RSA and CRT-RSA

In RSA, the public modulus N = pq is the product of two primes of the same bit-size, the public exponent e and the private exponent d satisfy ed ≡ 1 (mod (p−1)(q−1)). In many applications of RSA, d is chosen to be small. This was cryptanalyzed by Wiener in 1990 who showed that RSA is insecure if d < N. As an alternative, Quisquater and Couvreur proposed the CRT-RSA scheme in the decryption phas...

A New Partial Key Exposure Attack on Multi-power RSA

An important attack on multi-power RSA (N = pq) was introduced by Sarkar in 2014, by extending the small private exponent attack of Boneh and Durfee on classical RSA. In particular, he showed that N can be factored efficiently for r = 2 with private exponent d satisfying d < N. In this paper, we generalize this work by introducing a new partial key exposure attack for finding small roots of pol...

Attack on Private Signature Keys

The article describes an attack on OpenPGP format, which leads to disclosure of the private signature keys of the DSA and RSA algorithms. The OpenPGP format is used in a number of applications including PGP, GNU Privacy Guard and other programs specified on the list of products compatible with OpenPGP, which is available at http://www.pgpi.org/products. Therefore all these applications must und...
