%X A key escrow cryptosystem can provide protection for user's privacy, while at the same time, allows for the wiretapping when lawfully authorized. In this paper, a key escrow system based on RSA algorithm for network environment is given. A trusted center in this system specifies n trustees for every user, and distributes the part recovery ability of the user's secret key to n trustees by (t,n) threshold scheme. When the user broadcasts his encrypted key, only if at least t cooperated trustees can enforce the wiretapping to this user.
