This paper discusses a broadcasting multi-digital signature algorithm based on the elliptic curve cryptosystem. The method overcomes the problem of poor speed digital signature verification due to more complex operations, reduces relatively complex multiplication and point multiplication in the original broadcast multiple digital signature scheme, and avoids matrix inversion. It improves the speed of verification at the same time, and does not affect the security of the signature.
