A new code?based digital signature based on the McEliece cryptosystem

Digital signature schemes are used for the authentication and verification of signatures. The Courtois–Finiasz–Sendrier (CFS) digital is a well-known code-based scheme based on Niederreiter cryptosystem. However, it not widely due to computation time signing algorithm. Most This paper proposes new that McEliece Key generation, signing, algorithms presented. key generation algorithm constructs public using random inverse matrices. has lower complexity requires less than CFS sign document. able detect forgeries. It shown proposed secure against structural attacks.
