This paper presents an Internet voting protocol, which is primarily designed for limited voting devices such as smart cards or mobile phones. The minimum requirement for these devices is the ability to compute one ElGamal encryption and one DSA signature in reasonable time. The protocol is based on an anonymization mechanism for DSA public keys, which can be installed on top of an existing DSA ...
