In these protocols, a sender can obliviously transfer n messages to a receiver without communication with him/her. The public keys that a sender used to encrypt his/her messages are made by a third party. The receiver can extract k out of n messages at his/her choices by using the corresponding secret keys. The choices of the receiver are unconditionally secure. The sender's secrecy is guaranteed if the receiver is semi-honest in the %K oblivious transfer %K malicious oblivious transfer %K bilinear pairing %K bilinear Diffie-Hellman problems %U http://ojs.academypublisher.com/index.php/jsw/article/view/610
