Abstract :
This paper focuses on an investigation of the cross-correlation and auto-correlation properties of Blum (1986) sequences generated from integer rings of proven cryptographic strength to assess their usefulness and applicability to CDMA and spread-spectrum communications. Potentially, this will provide cryptographically secure communications on a CDMA or spread-spectrum system, at no overhead
