  • Device for and method of one-way cryptographic hashing
    Patent number: 6829355
    Abstract: The present invention is a device for and method of generating a hash value for a message by padding the message, loading the padded message into a first shift register that generates values according to a first rule of motion, initializing eight registers a, b, c, d, e, f, g, and h with user-definable values; converting the contents of the registers to hj=gj−1; gj=fj−1; fj=ej−1; ej=dj−1+T1, where T1=hj−1+&Sgr;1(ej−1)+Ch(ej−1, fj−1, gj−1)+Kj+Wj,; dj=cj−1; cj=bj−1; bj=aj−1; and aj=T1+T2, where T2=&Sgr;0(aj−1)+Maj(aj−1, bj−1, cj−1); computing H1(j)=a+H1(j−1); H2(j)=b+H2(j−1); H3(j)=c+H3(j−1); H4(j)=d+H4(j−1); H5(j)=e+H5(j−1); H6(j)=f+H6(j−1); H7(j)=g+H7(j−1); and H8(j)=h+H8(j&mi
    Type: Grant
