Abstract

A distributed security system is provided. The distributed security system uses a security policy that is written in a policy language that is transport and security protocol independent as well as independent of cryptographic technologies. This security policy can be expressed using the language to create different security components allowing for greater scalability and flexibility. By abstracting underlying protocols and technologies, multiple environments and platforms can be supported.

Claims

1. A method of transmitting a message between a first party and a second party, the method including:

receiving from the first party a message addressed to the second party, wherein the message is transported with a first transport and formatted in accordance with a first protocol;

determining a transport and protocol required by the second party from a security policy; and

transmitting the message to the second party using the transport and protocol required by the second party.

2. The method of claim 1, wherein:

the security policy identifies components of the security system.

3. The method of claim 1, wherein:

the security policy identifies access rights of the security system.

4. The method of claim 1, wherein:

the security policy language comprises the extensible markup language.

5. The method of claim 1, wherein:

the security policy is configurable.

6. The method of claim 1, wherein:

the security policy language comprises at least some logic-based components.

7. The method of claim 1, wherein:

the security policy language comprises at least some rule-based components.

8. The method of claim 1, wherein:

the security policy language comprises procedural components.

9. The method of claim 1, wherein the security policy includes an identity service.

10. The method of claim 1, wherein the security policy includes an admission service.

11. The method of claim 1, wherein the security policy includes a permission service.

12. The method of claim 1, wherein the security policy includes a revocation service.

13. The method of claim 1, wherein the security policy includes a mapping of entities to rights.

14. The method of claim 13, wherein the security policy further includes a mapping of entities to capabilities.
