Modified key agreement protocol based on the digitalsignaturestandard
Lein Harn · Electronics Letters · 1995
Arazi proposed a scheme to integrate a key exchange protocol into the DSS (digital signature standard) to authenticate two public keys exchanged between two users and then one corresponding secret session key can be shared by two parties based on the Diffie-Hellman public-key distribution scheme. Later, Nyberg and Rueppel pointed out a weakness in the Arazi protocol: if one secret session key is compromised then the others will be disclosed as well. The Letter proposes a modified key agreement protocol based on the DSS.
