User authentication over networks
Methods are provided for authenticating user authentication data, associated with a user ID, at an authentication system. The authentication system comprises an authentication server connected to a network, and a secure cryptoprocessor operatively coupled to the authentication server. A first token for the user ID is provided in data storage operatively coupled to the authentication server. The first token is produced by the secure cryptoprocessor by encoding the user authentication data associated with the user ID via an encoding process dependent on a secret key of the secure cryptoprocessor. The authentication server receives an authentication request for the user ID from a remote computer via the network. The authentication request comprises a ciphertext encrypting user authentication data under a public key of a first public-private key pair, the private key of which is secret to the secure cryptoprocessor. The authentication server supplies the ciphertext to the secure cryptoprocessor which decrypts the ciphertext using this private key to obtain plaintext user authentication data. The authentication server retrieves the first token for the user ID from the data storage. The authentication system checks for equality of the plaintext user authentication data and the user authentication data encoded in the first token via a cryptographic processing operation in which the authentication data is not exposed outside the secure cryptoprocessor. In response to such equality, the authentication server sends an authentication confirmation message to the remote computer via the network. |

Multi-tiered protection platform
A multi-tier platform provides security at a perimeter of a computer system, where an intermediate layer interacts between a web layer and an application layer. A data request that is associated with a data set is received at the web layer and passed to the intermediate layer. The intermediate layer determines the authoritative source for the data set and whether the data set has a static or dynamic value. If the value is static, the intermediate layer accesses the value stored at the intermediate layer. However, if the value is dynamic, the intermediate layer queries the source registered to the data set, obtains the value from the authoritative source, and returns the dynamic value via the web layer, where the registered source may be internal or external to the computer system. Consequently, the intermediate layer may function as an aggregate layer that supports both database and messaging services. |

Crosstalk reduction in electrical interconnects
Embodiments reduce crosstalk between electrical interconnects by offsetting pairs of electrical interconnects in an electrical system to produce a staggered interconnect pattern for which magnetic flux through a loop formed by a victim interconnect pair is effectively canceled. Magnetic field vectors generated by an aggressor pair of interconnects can pass through a loop-bounded surface defined by a victim pair of interconnects in the system. In the staggered interconnect pattern, the victim interconnect pair is offset with respect to the aggressor interconnect pair so that the field vectors passing through the victim pair's loop-bounded surface in one direction are substantially balanced by the field vectors passing through the victim pair's loop-bounded surface in the opposite direction, thereby minimizing the effect of the aggressor pair's magnetic field on the victim pair. Since crosstalk is proportional to the rate of change of the magnetic flux, reducing the magnetic flux can reduce the crosstalk. |
