An efficient authentication scheme using recovery information in signature

초록

This paper proposes an efficient authentication scheme for multicast packets using Recovery Information in Signature (RIS) to provide source authentication. The problems of the existing schemes are as follows: TESLA requires time synchronization between the sender and the receiver, and hashbased schemes have high communication overheads due to additional hash values and require many buffers and delay for verification on receivers. Our main focus is reducing the buffer size, communication, and computation burden of the receiver. The proposed scheme in this paper is highly robust to packet loss using the recovery layer based on XOR operation. It also provides low communication overhead, low verification cost, non-repudiation of the origin, immediate verification, and robustness against DoS attack on the receiver.
