How is it possible to use the AES encryption algorithm for an IBE (identity-based encryption) scheme?

It is possible to use AES encryption algorithm for an IBE (identity-based encryption) scheme.

Both are completely different. AES is an asymmetric encryption algorithm. Here the same key is used for both encryption and decryption.

On the other hand, IBE is a kind of asymmetric encryption. In asymmetric encryption, the message is encrypted with the public key and the receiver decrypts the message with the private key. But in general public keys are stored in public directory and public key certificates are needed to prove the authenticity of the public key. The management of public key directory and the public key certificate is complex.

So a new encryption scheme is proposed in which the public key is derived from the unique identity like Gmail of the user. So there will be no headache of certificate management.
