First sentence: We recall that a stream cipher is a symmetric cryptosystem in which plaintexts and ciphertexts are strings (or, in other words, finite sequences) of elements of a finite field Fq (with q elements), and encryption and decryption proceed by termwise addition, respectively subtraction, of the same string of elements of Fq.
