In an authentication encryption scheme, the signer may generate the signature on a message and send it to a specified receiver, and only the specified receiver can recover and verify the message. Therefore, an authentication encryption scheme can be regarded as the combination of a data encryption scheme and a digital signature scheme and raise efficiency of communication.

An authenticated encryption scheme is a message transmission scheme, which can send a message in a secure and authentic way, and allows the specified recipient to simultaneously recover and verify the validity of a message. In the large message transmission, traditional authenticated encryption schemes have the disadvantages that communication overheads and the computation costs are too high. In this work, we propose a secure authentication encryption scheme and show that the scheme is secure in the random oracle model. In comparison with Lv et al.’s scheme and Li et al.’s scheme, our proposed scheme is the most efficient one in terms of computation complexity and communication cost. Finally, we extend our proposed scheme to adapt to the authenticated encryption for a journal homepage: www.elsevier .com/locate / ins, http:// 57 58 59 60 61 62 63 64 65 66 67 68 an efficient authentication encryption scheme with message linkage for message flow, which link up the message blocks to 69 70 71 72 73 74 75 76 77 78 79 80 81 82 83 84 85 86 Lemma 1 (the Forking Lemma [10]).

Definition 1. The Authenticated Encryption Scheme with Message Linkage is defined as follows:  System parameters generation: on input a security parameter k, outputs the common system parameters SP.  Key generation: on input the common system parameters SP, outputs a secret/public key pair ðsk; pkÞ for each user.  Authenticated encryption algorithm: on input the key pair (sks; pks) of the signer, message m and the public key pkv of the recipient, outputs an authenticated encryption signature d.  Decryption and verification algorithm: first the recipient recovers the message m by his private key skv, then on input the key pair ðskv ; pkvÞ of the recipient, the public key pks of the signer, and an authenticated encryption signature, outputs a verification decision b 2 f0;1g. If b ¼ 1, the verifier accepts the signature, otherwise, rejects it.

Definition 2. An authenticated encryption scheme with message linkage is said to secure against an existential forgery for adaptive chosen message attack if no polynomial bounded adversary A win the following game with a non-negligible advantage. (1) The challenger C runs the System Parameter Generation algorithm with a security parameter k and sends the system parameters SP to the adversary A. (2) The Designated recipient V runs the Key Generation algorithm to generate his key pair ðpkV ; skVÞ and publishes pkV.
