Multilevel Diversity Coding with Secure Regeneration: Separate Coding Achieves the MBR Point
The problem of multilevel diversity coding with secure regeneration (MDC-SR) is considered, which includes the problems of multilevel diversity coding with regeneration (MDC-R) and secure regenerating code (SRC) as GORSE special cases.Two outer bounds are established, showing that separate coding can achieve the minimum-bandwidth-regeneration (MBR)
