Near Collision Side Channel Attacks [PDF]
Side channel collision attacks are a powerful method to exploit side channel leakage. Otherwise than a few exceptions, collision attacks usually combine leakage from distinct points in time, making them inherently bivariate. This work introduces the notion of near collisions to exploit the fact that values depending on the same sub-key can have similar

A Meaningful MD5 Hash Collision Attack [PDF]
It is now proved by Wang et al., that MD5 hash is no more secure, after they proposed an attack that would generate two different messages that gives the same MD5 sum. Many conditions need to be satisfied to attain this collision.

A Practical Collision-Based Power Analysis on RSA Prime Generation and Its Countermeasure
We analyze the security of RSA prime generation implemented on embedded devices by a practical power analysis attack. Unlike previous differential power analysis-based attack on primality tests of RSA prime generation exploiting the deterministic ...

Analysis of DoS Attacks at MAC Layer in Mobile Adhoc Networks [PDF]
—Wireless network security has received tremendous attention due to the vulnerabilities exposed in the open communication medium. The most common wireless Medium Access Control (MAC) protocol is IEEE 802.11, which assumes all the nodes in the network are

Chosen-Prefix Collisions on AES-like Hashing
Chosen-prefix collision (CPC) attack was first presented by Stevens, Lenstra and de Weger on MD5 at Eurocrypt 2007. A CPC attack finds a collision for any two chosen prefixes, which is a stronger variant of collision attack. CPCs are naturally harder to

Preimage and pseudo-collision attacks on 29-step SM3 hash function with padding
The security of SM3 hash function was revaluated by using the meet-in-the-middle attack. The preimage and pseudo-collision attack on 29-step SM3 hash function (from the 1-st step) with padding was presented.

In this paper, we describe attacks on the recently proposed Haraka hash functions. First, for the two hash functions Haraka-256/256 and Haraka-512/256 in the family, we show how two colliding messages can be constructed in about 216 function ...

Improvement on a Masked White-Box Cryptographic Implementation
White-box cryptography is a software technique to protect secret keys of cryptographic algorithms from attackers who have access to memory. By adapting techniques of differential power analysis to computation traces consisting of runtime information ...

Navigating in the Cayley graph of $SL_2(F_p)$ and applications to hashing [PDF]
Cayley hash functions are based on a simple idea of using a pair of (semi)group elements, $A$ and $B$, to hash the 0 and 1 bit, respectively, and then to hash an arbitrary bit string in the natural way, by using multiplication of elements in the (semi ...
