I implemented speck encryption in verilog and need help with decryption. Posted: 26 Apr 2019 12:58 PM PDT Basically, I'm an idiot. I followed the speck encryption algorithm provided in this wikipedia page: https://en.wikipedia.org/wiki/Speck_(cipher) I spent a bit of time designing a state machine which imitates this C code. It wasn't until after implementing it that I realized there was no code for the decryption. I did some googling and I did find some enc/dec example algorithms, but they're different enough that I'd basically have to recreate the state machine. I understand this may be necessary, but I'd really like to avoid it. Anyone think they can help me out? Maybe showing me the #define RR(x, y, k) that I could use for decryption? submitted by /u/psychocrow05 [link] [comments]
