A strong provably secure IBE scheme without bilinear map

作者：

Highlights：

• A one-way hash function is used to replace the symmetric-encryption in our protocol.

• Our protocol is proven to be secure against adaptively chosen identity attack.

• Our protocol is proven to be secure against chosen plaintext attacks.

• New scheme is efficient in terms of the time complexity for encryption/ecryption.
