func Decode ¶

func Decode(c []byte) *[761]int16

Decode unpacks an element of Rq packed by Encode.

func DecodeRounded ¶

func DecodeRounded(c []byte) *[761]int16

DecodeRounded unpacks an element of Rq packed by EncodeRounded.

func Encode ¶

func Encode(f *[761]int16) *[1218]byte

Encode packs an element of Rq into 1218 bytes.

func EncodeRounded ¶

func EncodeRounded(f *[761]int16) *[1015]byte

EncodeRounded packs an element of Rq rounded by Round3 into 1015 bytes.

func Mult ¶

func Mult(h, f *[761]int16, g *[761]int8)

Mult returns the product h of f and g in Rq.

func Reciprocal3 ¶

func Reciprocal3(r *[761]int16, s *[761]int8) int

Reciprocal produces the inverse r of a polynomial 3*s in Rq. If s is not invertible, Reciprocal returns -1, and 0 otherwise.

func Round3 ¶

func Round3(h, f *[761]int16)
