comment Is it ok to send part of digital signature if we have bandwidth constraints?
@RickyDemer Why MAC is preferred? Since we can have public/private key work in this case.

Recreate the signature and check whether the part is equal.

comment How to specify last $t$ bits are only sent when a signature is sent?
@CodesInChaos Is it possible to send only a part of signature? Like 16 bits?

Values of $J_A$ and $e$ are known. I am using example from GQ signature scheme from the book Page 451 cacr.uwaterloo.ca/hac/about/chap11.pdf

comment Shadowed identity in cryptography
Using the same example from the text, when I took $modularpow(J,phi−s,n)$, I am getting the value as -126739. I have J=34579, phi= 419184, s=233875 and n=420491

comment Shadowed identity in cryptography
One last question. There is an equation in the text "$s_A=(J_A)^{−s}mod\ n$". How could I calculate that? Taking $(J_A)^{−s}$ and taking mod n?
