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