Identity based broadcast encryption without pairings
Qiuliang Xu · Journal of Computer Applications · 2008
Identity Based Encryption(IBE)schemes and Identity Based Broadcast Encryption(IBBE)schemes are often constructed by using bilinear maps(a.k.a.parings)on elliptic curves.In this paper,an Identity Based Broadcast Encryption scheme without pairings was given.It is secure in Random Oracle according to the Quadratic Residuosity assumption.
