  • Ascon
    • Ascon-128 (WIP: Ascon-128a) AEAD and Hash
    • parameterized: unroll factor
    • fastest available FPGA implementation
    • winner of NIST LWC selection process
  • Gift-COFB
  • Gimli
  • Sparkle
  • subterranean
  • Xoodyak
    • AEAD and Hash
    • 1x/2x unroll
    • NIST LWC Round 2 and Round 3

BlueLight CryptoCore Interface and API

BlueLight sources are located in the bluelight directory.

BdIO is used for both input and output to/from CryptoCore.

typedef struct {
  CoreWord word;   // data word
  Bool lot;        // last word of the type
  Bit#(2) padarg;  // padding argument, number of valid bytes or 0 if all valid
} BdIO;

interface CryptoCoreIfc;
  method Action process(SegmentType typ, Bool empty); // after fire, 0 or more words of type `typ` will be processed by the CryptoCore
  interface FifoIn#(BdIO)  bdi; // input to CryptoCore
  interface FifoOut#(BdIO) bdo; // output from CryptoCore
endinterface
