A novel group key transfer for big data security

作者：

Highlights：

• We adopt DH key agreement and LSSS to design an efficient key transfer protocol without KGC.

• The proposed protocol can reduce the overhead of system implementation.

• The proposed protocol achieves key freshness, key confidentiality and key authentication.

• The confidentiality of the group key transfer phase is information theoretically secure.
