Measures for enhancing security in communication systems

A communication device configured for use in a method of providing security of operations on a connection between a first peer entity and the communication device as a second peer entity in a communication system, the peer entities each having an identity and a transport address, wherein the first peer entity requests an operation from the second peer entity using an identity, said communication device comprising:

• receiver devices configured to receive a request from the first peer entity;
• checker devices configured to check a permission of the first peer entity to be granted the requested operation using said identity by means of a pre-configured permissions list;
• first memory devices configured to store the pre-configured permissions list;
• and
• validator devices configured to validate the identity used by the first peer entity, wherein the validator devices are further configured to perform validating prior to the checker devices performing checking of the permission.

A system for providing security of operations on a connection between a first peer entity and a second peer entities in a communication system, the peer entities each having an identity and a transport address, wherein the first peer entity requests an operation from the second peer entity using an identity and the second peer entity checks a permission of the first peer entity to be granted the requested operation using said identity by means of a pre-configured permissions list, said system comprising:

• at least one first peer entity comprising
• transmitter devices configured to transmit a request for an operation to at least one second peer entity;
• and
• the at least one second peer entity comprising receiver devices configured to receive a request from the at least one first peer entity;
• checker devices configured to check the permission of the at least one first peer entity to be granted the requested operation using said identity by means of a pre-configured permissions list;
• first memory devices configured to store the pre-configured permissions list;
• and
• validator devices configured to validate the identity used by the at least one first peer entity,
• wherein the validator devices are further configured to perform validating prior to the checker devices performing checking of the permission.
