A Scheme of Data Encryption Based on Threshold Scheme and Elliptic Curve Cryptosystem
Tang Xiao-dong · Jisuanji gongcheng · 2004
This paper proposes a scheme of data encryption based on the (m,n)-threshold scheme and elliptic curve cryptosystem in which users are handled as an individual-user and a group-user. A group-user is a group made up of many (may be n) participants, each of whom holds a shadow of a common key (private key) different from one another. An individual-user is one who holds the key all by himself.
