A virtual machine project manager creates a generic, i.e., not user-specific, virtual machine image file. Copies of this image file may be distributed to one or more users, each of whom may then use an automated procedure to generate a user-specific virtual machine image file and, thus, a user-specific virtual machine on his/her remote host computer. The generic virtual machine image file may be distributed on computer-readable media, such as a DVD disks, or the file may be stored on a server and downloaded (such as via the Internet) by the users. Each user also receives or downloads a token, which contains a small amount of user-specific information that is used by the automated procedure to provision the generic virtual machine image file for the particular user. A virtual machine accesses a security token connected to a host computer to automatically authenticate or re-authenticate a user, such as when a virtual private network connection is restarted. Substantially identical session identifiers are used by a host computer and a virtual machine, or by two or more virtual machines and, when communicating with an integrated access server. A file server stores virtual machine images that are accessed by a plurality of host computers.

A method for providing a secure firmware update. A first authentication credential is securely stored on a platform in an encrypted form using a key generated by a secure token, such as a trusted platform module (TPM). Typically, the authentication credential will identify a manufacture and the operation will be performed during manufacture of the platform. A configuration of the platform is “imprinted” such that an identical configuration is required to access the key used to decrypt the first authentication credential by sealing the key against the platform configuration. During a subsequent firmware update process, a firmware update image containing a second authentication credential is received at the platform. If the platform configuration is the same as when the key was sealed, the key can be unsealed and used for decrypting the first authentication credential. A public key in the first authentication credential can then be used to authenticate the firmware update image via the second authentication credential.

Devices, systems and methods are disclosed for additional security, functionality, and convenience in the operation of a wireless communication device with the use of a separate proximity security token in communication with the wireless communication device. In exemplary embodiments, the token is carried by the user while device logic is installed on the user's wireless communication device. The device logic along with transceivers allows the device to sense proximity of the token through wireless communication. Given a certain range of the proximity security token, as determined by the wireless signal strength, the device logic determines whether the device is in a locked or unlocked state. If the proximity security token is outside the range, then the device is locked. The proximity security token uses ultra low power communications for optimal battery life.

An access control policy engine associated with a resource determines whether to allow a request to access same. The engine receives the request with an security token, retrieves the token determines a type thereof, and maps access decision information in the token to a common format as at least one security claim setting forth adequate information to determine a right of the requestor. Thereafter, the engine retrieves a set of rules for accessing the resource, applies the rules to the security claims to determine whether to allow the request from the requestor, and if the request is to be allowed, provides the requestor access to the resource in accordance with the request and the rights of the requestor as determined based on the security claims.

Systems, methods and apparatus for accessing at least one resource hosted by at least one server of a cloud service provider. In some embodiments, a client computer sends authentication information associated with a user of the client computer and a statement of health regarding the client computer to an access control gateway deployed in an enterprise's managed network. The access control gateway authenticates the user and determines whether the user is authorized to access the at least one resource hosted in the cloud. If the user authentication and authorization succeeds, the access control gateway requests a security token from a security token service trusted by an access control component in the cloud and forwards the security token to the client computer. The client computer sends the security token to the access component in the cloud to access the at least one resource from the at least one server.

Techniques are described for implementing a cloud computer system to facilitate communication between a computing device (e.g., a mobile computing device) and enterprise computer systems. In certain embodiments, the cloud computer system may receive, from a computing device, a request for a service provided by an enterprise computer system. The cloud computer system may determine security authentication of a user for the requested service. A security protocol may be determined for a requested enterprise computer system and a security token may be generated for the request according to the determined security protocol. The request may be sent to the requested enterprise computer system. In some embodiments, security authentication for a request to an enterprise computer system may be determined based on previous authentication. The cloud computer system may be configured to communicate with several different enterprise computer systems according to their supported protocols (e.g., communication protocol and/or security protocol).

A method and system for a client user remotely connected to a server computer by a client workstation such as a client personal computer to have securely displayed and to securely confirm that a request to access a resource on the server computer was actually requested by the client user, even if the security of the client computer has been compromised. This method and system can use conventional intelligent security tokens such as smart cards and associated smart card readers as a more secure environment to prompt for, and determine, the client user's intent to access the requested resource. A display securely accessible from the reader, smart card or both displays the resource (or resources) apparently being requested by client user. The client user is prompted to indicate whether it was their intention to access a resource by an input device associated with the reader or smart card.

An authentication server generates a security token to be used by a client for accessing multiple service providers by obtaining a secret key for each specified service provider, generating a saltbase, generating a salt for each service providers using the saltbase, the secret key, and a hashing algorithm, generating a session key that includes the salt, assigning an order to each of the generated salts, and arranging the salts based on the orders, generating a presalt for each provider using the salt for each previous provider, generating a postsalt for each of the specified service providers using the salt for each following provider, generating a blob for each of the specified service providers using the saltbase, the respective presalt, and the respective postsalt, inserting the generated blobs for the specified service providers in the security token, and providing the generated security token to the client workstation.

A method and apparatus are disclosed by which customers of an institution, such as a bank, may register one or more of their landline telephone or mobile telephone numbers and associate the telephone numbers with their account and thereafter in conjunction with a remote transaction, use the registered telephone to call into a bank system, or be called by a bank system, for verification, whereby the registered telephone becomes a security token that elevates the security of the transaction.

A method for electronic commerce using a security token and an apparatus thereof are provided. The electronic commerce method using a security token comprises a transaction approval institution generating a security token based on a security assertion markup language (SAML), using credit information of a purchaser who requests to issue a security token, and transmitting the security token to the purchaser; the purchaser writing an electronic signature on an order and transmitting the order together with the security token to a seller; the seller verifying the received order and security token, and then delivering goods according to the order to the purchaser; and the transaction approval institution performing payment for the seller and the purchaser. The method can solve the problems of personal information leakage and privacy infringement that may happen when a purchaser sends his personal information to a seller for electronic commerce. Since the token is one-time-use data, even if a security token sent is counterfeited or stolen, the loss can be minimized. In addition, by writing an extensible markup language (XML) electronic signature in the security token, authentication, integrity, and non-repudiation for a transmitted message can be guaranteed and through simple object access protocol (SOAP) security technology, confidentiality is maintained.

Devices, systems, and methods are disclosed which relate to an NFC-enabled security token that is removably coupled to a mobile device. The security token may be provisioned with the information by the mobile device, then decoupled from the mobile device and used to authenticate the user or perform a transaction at a POS terminal equipped with an NFC reader. The security token includes logic for user-controlled restrictions on allowable purchases, such as payment limits, timeouts, vendor identifiers, allowed purchases, and location-based restrictions. The security token is further equipped with “self destruct” security features, such as deactivating itself or erasing any sensitive information upon being unable to contact the mobile device for a specified duration, or being subject to an unauthorized or restricted transaction, until such time as it is re-coupled to the mobile device.

This patent application describes a data processing system and method for securely storing and retrieving a cryptographic secret from a plurality of network-enabled clients. The cryptographic secret is encrypted using a split key arrangement where a first key component is generated and stored inside a hardware security token and a second key component is generated and stored on a server. Random variables and dynamic passwords are introduced to mask the key components during transport. In order to gain access to the first password, the user is required to enter his or her PIN. The key encryption key is generated by performing a series of XOR operations, which unmasks the first and second key components on a client allowing generation of a symmetric key The symmetric key is used to encrypt the cryptographic secret at the user's normal client and decrypt the cryptogram at another client lacking the cryptographic secret. The applications performing the cryptographic functions are intended as browser applets, which remains in transient memory until the user's session has ended. At which time, the key encryption key and cryptographic secret are destroyed.

Security tokens contain data that is each uniquely encrypted based on a unique biometric identifier of an authorized user of that token. Decoders receive the token and the user's biometric identifier, convert the biometric identifier to a biometric key, and apply the biometric key to decrypt the token. In this way, the decoders authenticate the users without performing a biometric identifier comparison. In some embodiments pieces or sets of the data are stored in designated data compartments, which are individually encrypted based on authority keys, and all of the encrypted data compartments are collectively encrypted based on the biometric key to create the token. The decoders store only the authority keys corresponding to the data compartments which they have authorization to open. In addition, in some embodiments the token and the biometric identifier are encrypted and sent to a remote authentication server for decryption of the token.
