Abstract
Baldi et al. have introduced in [BBC+13] a very novel code based signature scheme. However we will prove here that some of the bits of the signatures are correlated in this scheme and this allows an attack that recovers enough of the underlying secret structure to forge new signatures. This cryptanalysis was performed on the parameters which were devised for 80i¾źbits of security and broke them with 100,i¾ź000 signatures originating from the same secret key.
