Functions ¶

func AggregateSignatures ¶

func AggregateSignatures(tss TSS, partialSigs []*bls_sig.PartialSignature, msg []byte) (*bls_sig.Signature, []byte, error)

AggregateSignatures aggregates partial signatures over the given message. Returns aggregated signatures and slice of signers identifiers that had valid partial signatures.

func PartialSign ¶

func PartialSign(sks *bls_sig.SecretKeyShare, msg []byte) (*bls_sig.PartialSignature, error)

PartialSign signs given message(msg) using given Secret Key Share(sks) and returns a Partial Signature.

func Verify ¶

func Verify(pk *bls_sig.PublicKey, msg []byte, sig *bls_sig.Signature) (bool, error)

Verify verifies the given signature(sig) on message(msg) with given public key (pk).

Types ¶

type PubShare ¶

type PubShare struct {
	Value *bls_sig.PublicKey
	// contains filtered or unexported fields
}

PubShare is a public share corresponding to a secret share.

type TSS ¶

type TSS struct {
	PubKey *bls_sig.PublicKey

	NumShares int
	// contains filtered or unexported fields
}

TSS (threshold signing scheme) wraps PubKey (PublicKey), verifiers (the public shares corresponding to each secret share) and threshold (number of shares).

func GenerateTSS ¶

func GenerateTSS(t, n int) (TSS, []*bls_sig.SecretKeyShare, error)

GenerateTSS returns a new random instance of threshold signing scheme and associated SecretKeyShares. It generates n number of secret key shares where t of them can be combined to sign a message.

func (TSS) Threshold ¶

func (t TSS) Threshold() int

Threshold returns the secret sharing threshold.
