A system and method for ensuring that machines having invalid or corrupt states are restricted from accessing host resources are provided. A quarantine agent (QA) located on a client machine acquires statements of health from a plurality of quarantine policy clients. The QA packages the statements and provides the package to a quarantine enforcement client (QEC). The QEC sends the package to a quarantine Health Certificate Server (HCS) with a request for a health certificate. If the client provided valid statements of health, the HCS grants the client health certificate that may be used in IPsec session negotiation.

Systems and methods for managing public key certificates and supporting the users thereof. The certificates are cryptographically encapsulated objects that bind the identities of their owners to public keys and provide digital signature mechanisms for other users to verify the binding and correctness of other attributes of the certificate. Certificates include double links that reflect their validation and position in a public certificates ledger, thereby preventing insertion or removal of certificates in the ledger. Certificate protocols of the system include requesting issuance of certificates, issuing and returning certificates to their requesting users, storing certificates in the certificates ledger, requesting and distributing certificates to transaction partners, verification of certificates by transaction partners, and revoking certificates by their owners. These protocols are performed as direct peer-to-peer transactions between the members of the system.

A method for self-service authentication of a client and a server. The method includes the server receiving an initialization command from the client. The initialization command may be transmitted to the server via a client web browser over an unsecured data transfer link. The method continues with requesting authentication information from the client. In response to receiving the authentication information from the client, the server transmits a client software component to the client. The client software component utilizes a client-side library installed on the operating system of the client to generate the various client credentials described above. Thereafter, the certificate signing request may be transmitted to a certificate server for signing the certificate signing request. The signed certificate signing request is then received by the client via the client web browser. The client utilizes the information associated with the signed certificate signing request with the client-side library installed on the client to generate a client certificate.

A system and method for searching and retrieving certificates, which may be used in the processing of encoded messages. In one embodiment, a certificate synchronization application is programmed to perform certificate searches by querying one or more certificate servers for all of the certificates on those certificate servers. If all of the certificates on a certificate server cannot be successfully retrieved using a single search query, due to a search quota on the certificate server being exceeded for example, the search is re-performed through multiple queries, each corresponding to a narrower subsearch. The invention enables users to large amounts of certificates to be automatically searched for and retrieved from certificate servers, thereby minimizing the need for users to manually search for individual certificates.

The OTPK module 40 is essential to the present embodiment. It may be considered to be a software module implemented on the signing entity 20. The OTPK module 40 may be dynamically downloaded for use or implemented as a pre-installed client plug-in.

The OTPK module 40 may be implemented as a PKCS#11 or CAPI DLL or a Java Applet or ActiveX plugin embedded within the Internet Web Browser. It may be automatically executed when performing secure transactions requiring digital signatures. The OTPK module 40 serves to independently and without additional instruction from a user carry out the steps of generating the asymmetric key pairs comprising the public key and the private key. The OTPK module 40 then contacts the authentication and certification server 50 for authenticating the identity of the signing entity 20. At this point, the user of the signing entity 20 may be prompted for a password or the password may have been entered earlier as part of a 2-factor authentication to the authentication and certification server 50. The private key is then automatically used to generate a digital signature for the signing entity 20. At this point onwards, the private key is then irretrievably deleted such that it cannot be re-used or copied for future use.
