摘要:

We consider the problem of determining the periodicity of a binary sequence, a problem of some importance in cryptography. A program for the solution of this problem is specified using a functional notation. Results on the likely period of a random binary sequence are developed. We discuss the benefits of using a functional specification both for the case study and in general.
