A novel authenticated encryption scheme with convertibility
In 1993 Nyberg and Rupeel proposed an authenticated encryption scheme (AES) based on the DSA algorithm that reduces the computation time and communication costs for authenticated message transmission. Motivated by this, several researchers developed further AES approaches. However, when a dispute oc...

| Summary: | In 1993 Nyberg and Rupeel proposed an authenticated encryption scheme (AES) based on the DSA algorithm that reduces the computation time and communication costs for authenticated message transmission. Motivated by this, several researchers developed further AES approaches. However, when a dispute occurs between the sender and recipient, there is no mechanism for verification by a third party. To address this problem, in 2002 Wu and Hsu added an additional requirement of convertibility. However, to date there has been no scheme that satisfies all the properties of an ideal AES. In this paper, we propose a scheme that satisfies all the properties of an ideal AES. |
