Susceptibility of digital signature schemes based on error-correcting codes to universal forgery
M. Alabbadi, Stephen B. Wicker · 2002
Xinmei's (1990) digital signature scheme and the scheme's modified version as proposed by Harn and Wang have been shown by the authors and others to be susceptible to several different attacks. The authors have since devised and presented a scheme that is impervious to the attacks that were successfully applied to the earlier schemes. It is shown that this new scheme and Xinmei's scheme are vulnerable to universal forgeries. Equipped with this attack and the earlier ones, general remarks about digital signature schemes based on linear error-correcting block codes are presented.>
