A user authentication protocol for digital mobile communication network
Liu Jianwei, Wang Yu-min · 2002
A new public-key user authentication protocol for mobile communication network is presented based on Harn (see Electronics Letters, vol.30, no.5, p.396, 1994) proposed modified ElGa-mal signature system and Rabin cryptosystem. It overcomes the shortcomings of secret-key authentication protocol used in GSM and CT-2 systems, and a has lower computational complexity and a higher security.
