I would like to know how can I solve the following issue:(All relevant to Oracle 8i)
Consider an oracle DBA(A) sends a procedure to user(B).After 'B' used the procedure he sends it back to A.
It's like: A->B->A
After 'A' receives the message, he checks the message and want to be sure that 'B'did not modify or change the procedure.How can I do this?Should I use digital signature or hash?
I appreciate your help.
Thanks a lot.
I would like to use digital signature for the above question.So please give me some tips for using digital signature.
