Key Recovery Attack for All Parameters of HFE-

2017
Recently, by an interesting confluence, multivariate schemes with the minus modifier have received attention as candidates for multivariate encryption. Among these candidates is the twenty year old HFE\(^-\) scheme originally envisioned as a possible candidate for both encryption and digital signatures, depending on the number of public equations ...

Key Recovery Attacks on Recent Authenticated Ciphers

2015
In this paper, we cryptanalyze three authenticated ciphers: AVALANCHE, Calico, and RBS. While the former two are contestants in the ongoing international CAESAR competition for authenticated encryption schemes, the latter has recently been proposed for lightweight applications such as RFID systems and wireless networks.

Key Recovery Attacks on the RMAC, TMAC, and IACBC

2003
The RMAC[6] is a variant of CBC-MAC, which resists birthday attacks and gives provably full security. The RMAC uses 2k-bit keys and the size of the RMAC is 2n, where n is the size of underlying block cipher. The TMAC[10] is the improved MAC scheme of XCBC[4] such that it requires (k + n)-bit keys while the XCBC requires (k + 2n)-bit keys. In this paper,

Equivalent Inner Key Recovery Attack to NMAC

2013
We propose a general equivalent inner key recovery attack to the NMAC (Nested Message Authentication Code) instantiated with secure hash function in a related key setting, by applying a generalized birthday attack with two groups. We can recover the equivalent inner key of NMAC in about 2 n/2 + 1 on-line MAC queries.
