Cryptanalysis of a generic one-round key exchange protocol with strong security
MetadataShow full item record
In Public-Key Cryptography (PKC) 2015, Bergsma et al. introduced an interesting one-round key exchange protocol (which will be referred to as BJS scheme) with strong security in particular for perfect forward secrecy (PFS). In this study, the authors unveil a PFS attack against the BJS scheme. This would simply invalidate its security proof. An improvement is proposed to fix the problem of the BJS scheme with minimum changes.
