Exemplary methods for facilitating secure communication between a mobile network subscriber and various service providers (SPs), the subscriber being associated with a plurality of entities comprising any combination of devices and profiles. Some embodiments can include: obtaining a security identifier associated with the subscriber; based on the security identifier, establishing an identity hierarchy comprising the plurality of entities associated with the subscriber; based on the security identifier, establishing consents for SPs to access data generated by the entities of the identity hierarchy; in response to a request comprising the security identifier, receiving a public key usable to encrypt data for sending to a particular SP, the data being decryptable using a corresponding secret key associated with an established consent for the particular SP; and encrypting the data using the public key and the identity hierarchy. Embodiments also include subscriber devices and server apparatus configurable to perform the exemplary methods.

Systems and methods for ensuring multi-tenant isolation in a data center are provided. A switch, or virtualized switch, can be used to de-multiplex incoming traffic between a number of data centers tenants and to direct traffic to the appropriate virtual slice for an identified tenant. The switch can store tenant identifying information received from a master controller and packet forwarding rules received from at least one tenant controller. The packet handling rules are associated with a specific tenant and can be used to forward traffic to its destination.
