Hello, I am trying to verify the safety of optimized ANSI C code for the Rijndael cipher (now AES) with frama-c/jessie/why, but I am trouble in the abstracting of loop invariants. I added some loop invariants according to my ideas, while many VCs on loops can not be discharged. Is there anybody who can help me to abstract proper loop invariants? The attachment is the source code with some lemmas and loop invariants written in ACSL. The source code is a bit long, thanks for your patience! -------------- next part -------------- An HTML attachment was scrubbed...
