This book constitutes the refereed proceedings of the 8th International Conference on Sequences and Their Applications, SETA 2014, held in Melbourne, VIC, Australia, in November 2014. The 24 full papers presented together with 2 invited papers were carefully reviewed and selected from 36 submissions. The papers have been organized in topical sections on Boolean functions, perfect sequences, correlation of arrays, relative difference sets, aperiodic correlation, pseudorandom sequences and stream ciphers, crosscorrelation of sequences, prime numbers in sequences, OFDM and CDMA, and frequency-hopping sequences.Relationships Between CCZ and EA Equivalence Classes and Corresponding Code Invariants.- Boolean Functions.- Results on Constructions of Rotation Symmetric Bent and Semi-bent Functions.- Properties of a Family of Cryptographic Boolean Functions.- A New Transform Related to Distance from a Boolean Function (Extended Abstract).- Constructing Hyper-Bent Functions from Boolean Functions with the Walsh Spectrum Taking the Same Value Twice.- Characterizations of Plateaued and Bent Functions in Characteristic.- Perfect Sequences.- A Method of Optimisation of the Exhaustive Computer Search for Perfect Sequences.- Almost Six-Phase Sequences with Perfect Periodic Autocorrelation Function.- A Construction for Perfect Periodic Autocorrelation Sequences.- A Simple Construction of Almost Perfect Quinary ASK and QAM Sequences.- Correlation of Arrays.- Inflation of Perfect Arrays Over the Basic Quaternions of Size mn ? ?q ? 1?=2.- Families of 3D Arrays for Video Watermarking.- Relative Difference Sets.- The Nonexistence of ?18; 3; 18; 6?
