    摘要： A cryptographic facility implements a multiple key part import procedure. The installation manager can verify that a key part has been correctly entered and has not been compromised. The security requirement for the procedure is that no single party can subvert the system security by misusing the procedure. This is accomplished by the use of a control-vector-dependent verification pattern to indicate that each key part has been accepted by using the proper control vector and the use of different key switch positions to specify whether the key part is a master key part or an operational key part and whether the key part is a first part or a subsequent key part. The apparatus provides an automatic reset of the key part register at the completion of each key-entry instruction so that each key part can be imported only once. This prevents the same key part from being imported twice as different key part types. The apparatus also prevents a key part from being combined with itself to create a known key. The procedure is fail-safe so that the program cannot steal a key part from a previously failed procedure.

    摘要： A working key of a certain key type is to be transmitted from a first system (having a first usage-control value associated with keys of the certain type) and a second system (having a second usage-control value associated with keys of the certain type). A translation control value, associated with the certain key type, is generated, functionally relating the first and second usage-control values. The translation control value is used in a cryptographic function to send or receive the working key between systems, the cryptographic function being designed to produce valid results when the correct translation control value, and usage-control values, are employed, and unpredictable results otherwise. Effectively, the first usage-control value is translated to the second usage-control value.

    摘要： The invention is an apparatus and method for validating that key management functions requested for a cryptographic key by the program have been authorized by the originator of the key. The invention includes a cryptographic facility characterized by a secure boundary through which passes an input path for receiving the cryptographic service requests, cryptographic keys and their associated control vectors, and an output path for providing responses thereto. There can be included within the boundary a cryptographic instruction storage coupled to the input path, a control vector checking unit and a cryptographic processing unit coupled to the instruction storage, and a master key storage coupled to the processing means, for providing a secure location for executing key management functions in response to the received service requests. The cryptographic instruction storage receives over the input path a cryptographic service request for performing a key management function on a cryptographic key. The control vector checking unit has an input coupled to the input path for receiving a control vector associated with the cryptographic key and an input connected to the cryptographic instruction storage, for receiving control signals to initiate checking that the control vector authorizes the key management function which is requested by the cryptographic service request. The control vector checking unit has an authorization output connected to an input of the cryptographic processing means, for signalling that the key management function is authorized, the receipt of which by the cryptographic processing unit initiates the performance of the requested key management function with the cryptographic key. The invention enables the flexible control of many cryptographic key management functions in the generation, distribution and use of cryptographic keys, while maintaining a high security standard.

    摘要： Cryptographic PIN processing is achieved in an improved manner by associating control vectors with the PIN generating (verification) keys and PIN encrypting keys which provide authorization for the uses of the keys intended by the originator of the keys. The originator may be the local cryptographic facility (CF) and a utility program under the control of a security administrator, or the originator may be another network node which uses the key management methods described in the above-referenced copending patent applications to distribute said keys.Among the uses specified by the control vector are limitations on the authority to use the associated key with certain PIN processing instructions, such as PIN generation, verification, translation and PIN block creation. Furthermore, the control vector may limit the authority of certain instructions to process clear PIN inputs (such as in PIN verification). The control vector may contain information identifying and, possibly restricting, PIN processing to a particular PIN format or particular processing algorithm.The control vector implementation provides a flexible method for coupling format, usage, and processing authorization to keys. The system administrator can exercise flexibility in changing the implementation of his security policy by selecting appropriate control vectors in accordance with the invention. Furthermore, a method is provided for the security administrator to restrict certain PIN format translations.

    摘要： A method and system are disclosed for securely distributing a plurality of software files from a software distribution processor to a user processor, while selectively enabling the user processor to only use a subset of a lesser plurality of the software files. This is achieved by employing a customer key which includes a clear customer number and a derived portion derived from the customer number. The customer key is transformed into a second customer key which serves as a key expression for encrypting a file encryption key specifically intended for a respective one of the plurality of files. A plurality of software files can be stored together, for example on a CD-ROM, with each file encrypted under a corresponding file encryption key. The CD-ROM can be distributed to many user processors. When a specific user processor needs to run one of the software files, a request will be transmitted from the user processor to the software distribution processor. In response to that request, an encrypted file encryption key specific for the requested file, will be transmitted to the user processor. This will enable the user processor to decrypt only the requested file from the CD-ROM. All other files on the CD-ROM remain in their encrypted form and cannot be decrypted and used by the file encryption key received from the software distribution processor.

    摘要： The invention includes a control vector checking code respository located either within the same system as the crytographic facility or alternately remotely from the system containing the cryptographic facility. The control vector checking code repository will be linked to the cryptographic facility by one of several means. A first means for linking the repository to the cryptographic facility would include a physically secure data communications link. A second means for connecting the repository to the cryptographic facility would be by using an insecure channel with authentication, wherein either a modification detection code or alternately a message authentication code would be transmitted to the cryptographic facility and then the desired control vector checking code would be transmitted over the link. The cryptographic facility will include a code authorization mechanism to compare the transmitted MAC or MDC with a corresponding value computed from the received control vector checking code. If the two values of the MDC or the MAC compare, then the control vector checking code is authenticated and loaded into the control vector checking unit for carrying out the control vector checking operations desired. The control vector checking code repository can be located in a remote system connected by means of the communications link to the crypto facility, or alternately the repository can reside in the same system as the crypto facility. This provides for the dynamic updating of control vector checking code, where improvements or alterations are made to the control vector checking sequence. This also provides for a reduced memory size in the crypto facility, being sufficiently large to accommodate subsidiary control vector checking applications, with alternate control vector checking applications requiring the reloading of the control vector checking unit from the repository.
