Functions ¶
func NewAggregateSignature ¶
func UnaggregatedSignatures ¶
Types ¶
type DilithiumKey ¶
DilithiumKey represents a BLS secret or private key.
func SecretKeyFromBytes ¶
func SecretKeyFromBytes(seed []byte) (DilithiumKey, error)
TODO (cyyber): Rename SecretKeyFromBytes to SecretKeyFromSeed
type PublicKey ¶
PublicKey represents a BLS public key.
func AggregatePublicKeys ¶
func PublicKeyFromBytes ¶
type Signature ¶
Signature represents a BLS signature.
func SignatureFromBytes ¶
type SignatureBatch ¶
type SignatureBatch struct {
Signatures [][]byte
PublicKeys [][]PublicKey
Messages [][32]byte
Descriptions []string
}
SignatureBatch refers to the defined set of signatures and its respective public keys and messages required to verify it.
func (*SignatureBatch) AggregateBatch ¶
func (s *SignatureBatch) AggregateBatch() (*SignatureBatch, error)
AggregateBatch aggregates common messages in the provided batch to reduce the number of pairings required when we finally verify the whole batch.
func (*SignatureBatch) Copy ¶
func (s *SignatureBatch) Copy() *SignatureBatch
Copy the attached signature batch and return it to the caller.
func (*SignatureBatch) Join ¶
func (s *SignatureBatch) Join(set *SignatureBatch) *SignatureBatch
Join merges the provided signature batch to out current one.
func (*SignatureBatch) RemoveDuplicates ¶
func (s *SignatureBatch) RemoveDuplicates() (int, *SignatureBatch, error)
RemoveDuplicates removes duplicate signature sets from the signature batch.
func (*SignatureBatch) Verify ¶
func (s *SignatureBatch) Verify() (bool, error)
Verify the current signature batch using the batch verify algorithm.
func (*SignatureBatch) VerifyVerbosely ¶
func (s *SignatureBatch) VerifyVerbosely() (bool, error)
VerifyVerbosely verifies signatures as a whole at first, if fails, fallback to verify each single signature to identify invalid ones.
