A public key infrastructure (PKI) plays an important role in utilizing a digital certificate as user’s digital identifier in a reliable manner. Due to the users’ demands for using their digital identifiers in places, a need for PKI roaming is rapidly growing in such a promising infrastructure. Cooperating with multiple servers must be a practical way to secure PKI roaming in software-based environments. This paper describes a new method of running RSA algorithms with a multitude of servers, in a way that a human user keeps an ID and password pair only. Our basic idea is to hide a real ID and split a password as well as a private exponent over multiple servers, so as to generate signatures or decrypt messages via the so-called virtual software tokens.
