Amplifying Collision Resistance: A Complexity-Theoretic Treatmentask participants to make confidence judgments about the efficacy of some aspect of their cognition or memory. We are concerned that, in our haste to understand metacognition, we mistakenly equate the judgments we elicit from participants with the processes that underlie them. We assert here that mul

Susceptibility Testing of , Isolatesad introduced in 1998. The attack only needs the public key and requires about one second to forge a signature for any message, after a one-time computation of several minutes. It can be applied to both SFLASH. which was accepted by NESSIE, as well as to SFLASH. which is a higher security version.

Conversely, at Asiacrypt ’06, Contini and Yin used collision techniques to obtain forgery and partial key-recovery attacks on HMAC and NMAC instantiated with MD4, MD5, SHA-0 and reduced SHA-1. In this paper, we present the first full key-recovery attacks on NMAC and HMAC instanti
