Abstract :
Based on Gentry´s identity based encryption, an identity based proxy re-encryption scheme is proposed and it is proved fully secure in the standard model under the truncated decision q-ABDHE (augmented bilinear Diffie-Hellman exponent) assumption with a tight security reduction and very compact public parameters. It is also very efficient and practical.
