This paper describes a counter scheme that uses hash functions to count how many times the user is allowed to play protected content in a DRM-enabled player. The proposed basic sc...
: In this paper, we will propose a new synchronous stream cipher named DICING, which can be taken as a clock-controlled one but with a new mechanism of altering steps. With the sim...
Recently, Tian et al. presented an article, in which they discussed some security weaknesses of Yoon et al.'s scheme and subsequently proposed two "improved" scheme...
In this paper we consider an attack on the SIGABA cipher under the assumption that the largest practical keyspace is used. The attack highlights various strengths and weaknesses o...
Key authentication is very important in private communication and data integrity. Recently, Peinado, Zhang and Kim showed that the LHL scheme is not secure, respectively. From pub...
