  This paper proposes a new class of random sequences called binary primes
tableau (PT) sequences that have potential applications in cryptography and
communications. The PT sequence of rank p is obtained from numbers arranged in
a tableau with p columns where primes are marked off until each column has at
least one prime and where the column entries are added modulo 2. We also
examine the dual to the PT sequences obtained by adding the rows of the
tableau. It is shown that PT sequences have excellent autocorrelation
properties.
