... Responsible Disclosure Process. Since WalnutDSA is advertised as a security product by SecureRF, we notified its authors of our findings before making them available to the public. We informed them by email on ... See full document

... We have presented four attacks where an adversary with a Quantum Computer is able to attempt against NTRUEncrpyt (as implemented by the current NTRU library). One of the key recovery attacks actually attacks the key ... See full document

... Abstract. In this article, we analyse the security of the authenticated encryption mode JAMBU, a submission to the CAESAR competition that remains currently unbroken. We show that the security claims of this candidate ... See full document

... Despite aforementioned attacks and studies on provable security, it is widely believed that the security proofs are correct, thus all versions of OCB are prov- ably secure in the standard, nonce-respecting scenario, up ... See full document

... We propose a new attack on multi-HFE to recover equivalent secret keys for odd characteristic cases, which is much faster than the the min-rank attack [4]. While our attack is not presently available for even ... See full document

... The practical relevance of our attacks is demonstrated by our solution of the rst three concrete Legendre PRF challenges proposed by the Ethereum foundation ... See full document

... There are many practical issues that have been considered when implementing RSA cryp- tosystem to reduce the encryption process or the execution decryption time. If the secret exponent d is relatively small, then ... See full document

... The paper gives practical key-recovery and message-recovery attacks against those parameter sets of IEC through lattice basis-reduction algorithms. We exploit the fact that n = 80 is composite and adopt the idea ... See full document

... Our first attack, described in Section 3, in a known-plaintext attack against the symmetric-key CLS scheme. We establish that a few known plaintext-ciphertext pairs are sufficient to decrypt any ciphertext. This attack ... See full document

... MISTY [Mat97] is a block cipher designed by Matsui in 1997 and is based on the theory of provable security [Nyb94,NK95] against differential attack [BS90] and linear attack [Mat93]. MISTY has a recursive structure, and ... See full document

... In general, one may expect that the special internal states to be stored are deduced by exhaustively searching them. However, we can deduce these states without a search-and-eliminate mechanism, reducing the time ... See full document

... Our Results. Table 1 summarises the results of the different attacks on the authenticated encryption scheme of OSGP and also lists the corresponding sections where the attacks are described. While the attacks have ... See full document
