Abstract: An improved methodology and implementing computer system are provided in which sensitive information is selectively masked in order to enable such information to be relatively securely and efficiently transmitted over networks without disclosure of such sensitive information at a transmitting or receiving terminal, or at points along the data transmission network.

Abstract: Method, system, and program product for port based authentication protocols where addresses are dynamically assigned within a network environment, and more particularly to port based authentication in the network environment, where connection information is captured and stored. This facilitates administrator access to information created as a result of protocol exchanges involved in dynamic address assignment, authentication, and connection.

Abstract: A system to exchange and authenticate public cryptographic keys between parties that share a common but secret password, using a pair of random numbers, a pair of Diffie-Hellman public keys computed from the random numbers and the password, a Diffie-Hellman symmetric secret key computed from the Diffie-Hellman public keys and the random numbers, and hashed values of arguments that depend upon these elements.

Abstract: A method to distribute and authenticate public encryption keys. A client concatenates its ID, its public key, and a secret password known to the client and a server, and hashes the result. The client forms an extended concatenation including the ID, the public key, and the hashed value, and sends the extended concatenation to the server. The server reads the ID and public key, and re-computes the hashed value based on its own knowledge of the password. If the received and the computed hashed values are the same, the server concludes that the client's public key is authentic. An analogous process enables the server to distribute its public key, and enables the client to authenticate the server's distributed public key.

Abstract: A method, apparatus, and computer instructions for providing a current and complete security compliance view of an enterprise system. The present invention provides the ability to gain a real-time security posture and security compliance view of an enterprise and to assess the risk impact of known threats and attacks to continued business operations at various levels is provided. Responsive to a change to an enterprise environment, a request, or an external threat, an administrator loads or updates at least one of a Critical Application Operations database, a Historical database, an Access Control database, a Connectivity database, and a Threat database. Based on a comparison of information in the databases against similar security data elements from company or external policies, the administrator may generate a Security Compliance view of the enterprise. A Security Posture view may also be generated by comparing the Security Compliance view against data in the Threat database.

Abstract: A method to exchange and authenticate public cryptographic keys between parties that share a common but secret password. The parties exchange public keys, where the public keys are accompanied by hashed values based on the keys, the password, and random numbers. Each party then encrypts its random number using the public key of the other party, and the encryptions are exchanged. Based on the received encryptions and the known password, each party then re-computes the hashed value received from the other party, and compares the re-computed hashed value with the received hashed value. If the two are the same, the public key that accompanied the hashed value is judged authentic.

Abstract: A method for protecting data for access by a plurality of users. A server encrypts data using a master key and a symmetric encryption algorithm. For each authorized user, a key encryption key (KEK) is derived from a passphrase, and the master key is encrypted using the KEK. The server posts the encrypted data and an ancillary file that includes, for each user, a user identifier and the master key encrypted according to the user's KEK. To access the data, a user enters the passphrase into a client, which re-derives the user's KEK, and finds, in the ancillary file, the master key encrypted using the user's KEK. The client decrypts the master key and then decrypts the data. A KEK may be derived from a natural language passphrase by hashing the passphrase, concatenating the result and a predetermined text, hashing the concatenation, and truncating.

Abstract: Methods, systems and computer program products are provide for controlling access to software is provided by the software to be controlled being divided into a first encrypted portion and a second unencrypted portion. The second unencrypted portion has access to, and may even incorporate, a first secret value and a software identification associated with a copy of the software. The first encrypted portion is encrypted with a first key value which is based on the first secret value and a second secret value. The second secret value is obtained and the first key value generated from the obtained second secret value and the first secret value. The first encrypted portion of the software may then be decrypted with the first key value. The software may be installed on a data processing system utilizing the decrypted first encrypted portion of the software.

Abstract: Methods, systems and computer program products are provided which generate an RSA cryptographic value by obtaining user specific information about a user and determining a user specific range of values based on the user specific information. The potential range of RSA prime values is divided into at least two subintervals and the user specific range of values mapped onto a first of the at least two subintervals. A first user-dependent RSA prime is then selected from the range of RSA prime values in the first subinterval corresponding to the mapped user specific range of values.

Abstract: Methods, systems and computer program products are provided which allow for generation and authentication of RSA encrypted values by utilizing a combination of entity specific information such as biometric information and by incorporating information about the secret seeds into the cryptographic values p and q utilized to encrypt the information. Thus, authentication of an encrypted message may be achieved without requiring storage of the secret seed values utilized to generate the cryptographic values. Furthermore the present invention assures that users with different entity specific information utilize different p and q values.
