By Dingyi Pei

Researchers and practitioners of cryptography and data safeguard are regularly challenged to reply to new assaults and threats to details structures. Authentication Codes and Combinatorial Designs offers new findings and unique paintings on ideal authentication codes characterised when it comes to combinatorial designs, particularly robust partly balanced designs (SPBD).

Beginning with examples illustrating the recommendations of authentication schemes and combinatorial designs, the ebook considers the likelihood of winning deceptions by way of schemes concerning 3 and 4 individuals, respectively. From this aspect, the writer constructs the best authentication schemes and explores encoding principles for such schemes in a few precise cases.

Using rational basic curves in projective areas over finite fields, the writer constructs a brand new kin of SPBD. He then offers a few confirmed combinatorial designs that may be used to build excellent schemes, reminiscent of t-designs, orthogonal arrays of index team spirit, and designs developed via finite geometry. The e-book concludes by way of learning definitions of ideal secrecy, houses of completely safe schemes, and buildings of excellent secrecy schemes with and with no authentication.

Supplying an appendix of development schemes for authentication and secrecy schemes, Authentication Codes and Combinatorial Designs issues to new functions of combinatorial designs in cryptography.
