How to achieve non-repudiation of origin with privacy protection in cloud computing

作者：

Highlights：

• We define two security goals of the non-repudiation of origin: NRO-I and NRO-II.

• We show that the (strongly) existential unforgeability of digital signatures is not sufficient to provide NRO-II.

• We define the privacy of message sender in communication protocols with non-repudiation of origin.

• We describe a communication protocol where the non-repudiation of origin and the privacy of message originator co-exist.
