Threshold Signature Scheme Based on Rabin Cryptosystem
Xiao Guo-zhen · 2004
Threshold cryptography provides a way in which the secret key can be shared secretly. Threshold signature is a part of the threshold cryptography. This paper has proposed a threshold signature scheme, which is a combination of digital signature scheme and secret sharing scheme over finite abelian group, based on Rabin cryptosystem. Also the efficiency and security of the scheme are discussed.
