Title:
SYSTEM, APPARATUS AND METHOD FOR EFFICIENT MULTICAST KEY DISTRIBUTION
Document Type and Number:
WIPO Patent Application WO/2012/160137
Kind Code:
A3
Abstract:
A system, apparatus and method are disclosed for efficient distribution of keys with security information purposes. In one aspect, one apparatus, the key server, is in charge of generating the information that is needed to encrypt the key using an orthogonal decomposition of a vector space and assign information that determine uniquely every authorized user and to distribute the key. In another aspect a plurality of apparatus receive and transmit the encrypted key and, using the information that determines them are able to get the key by means of a scalar product and that allows access to some digital information that can be sent by the key server itself or another server using the encryption key.
