Patent ID: 8880889

Claim:
A method of managing remote communications on a remote wireless device using a Public Key Infrastructure (PKI) system, comprising the steps of: receiving at a centralized system a message containing at least one transaction request transmitted by a user using the remote wireless device which is digitally signed by the user using a private key associated with the user, accompanied by a token from a security token service which contains data or information relating to the user's entitlements and which is digitally signed by the security token service using a second private key associated with the security token service, said centralized system containing information relating to the entitlements required for at least the requested transaction; communicating with a first trusted third party to authenticate the transaction request using a public key associated with the user, wherein the first-trusted third party operates independently of the user; communicating with a second trusted third party to authenticate the token using a key associated with the security token service, wherein the second trusted third party operates independently of the token service; verifying at the centralized system, the entitlement information contained in the token to confirm whether the user is authorized to perform the requested transaction; and performing the requested transaction if the user's entitlements satisfy required entitlements associated with the requested transaction.
