Navi che portano nell’aldilà: la raffigurazione del bivium in El viaje del alma di Lope de Vega [PDF]
Studi E Saggi, 2021 The bivium of human life, narrated in the myth of Hercules and symbolized by the Pythagorean Y, was a recurring motif in Spanish theater since the second half of the sixteenth century. Lope de Vega already developed it in one of his most remote sacramental plays, Comedia del viaje del hombre.

Attacking Bivium and Trivium with the Characteristic Set Method
Lecture Notes in Computer Science, 2011 In this paper we utilize an algebraic method called the characteristic set method to attack Bivium and Trivium in the guess-and-determine way. Our attack focuses on recovering the internal states of these two ciphers. We theoretically analyze the performance of different guessing strategies in the guess-and-determine method and present a good one.

Improved Algebraic Cryptanalysis of QUAD, Bivium and Trivium via Graph Partitioning on Equation Systems [PDF]
Lecture Notes in Computer Science, 2010 We present a novel approach for preprocessing systems of polynomial equations via graph partitioning. The variable-sharing graph of a system of polynomial equations is defined. If such graph is disconnected, then the corresponding system of equations can be split into smaller ones that can be solved individually.

Guess and Determine Attack on Bivium [PDF]
Journal of Information Processing Systems, 2011 Bivium is a simplified version of Trivium, a hardware profile finalist of the eSTREAM project. Bivium has an internal state size of 177 bits and a key length of 80 bits. In this paper, a guess and determine attack on this cipher is introduced. In the proposed method, the best linear approximations for the updating functions are first defined.
