Method and apparatus for secure transmission of data and applications

Authenticated transmissions are usually time-consuming and often provide delayed error recognition and correction. This is a problem particularly with hand-held computing devices like personal digital assistants (PDAs), smart phones or smartcards, since these usually possess limited memory, processing power and communications bandwidth. Because of these limitations and generally low transfer rates between the device and a provider or central computer base, such transmissions are time-consuming and delay applications. The late detection of unavoidable transmission errors is especially cumbersome. By applying an optimally taylored authentication scheme to a block-wise transmission and in particular by applying a tree structure for the authentication process during such transfers, the present invention minimes the unavoidable delays and thus provides a solution for these problems.

Insulated Gate-Type Semiconductor Device and Manufacturing Method Thereof

A semiconductor 100 has a P− body region and an N− drift region in the order from an upper surface side thereof. A gate trench and a terminal trench passing through the P− body region are formed. The respective trenches are surrounded with P diffusion regions at the bottom thereof. The gate trench builds a gate electrode therein. A P−− diffusion region, which is in contact with the end portion in a lengthwise direction of the gate trench and is lower in concentration than the P− body region and the P diffusion region, is formed. The P−− diffusion region is depleted prior to the P diffusion region when the gate voltage is off. The P−− diffusion region serves as a hole supply path to the P diffusion region when the gate voltage is on.

Methods for preparation of lipid-encapsulated therapeutic agents

Fully lipid-encapsulated therapeutic agent particles of a charged therapeutic agent are prepared by combining a lipid composition containing preformed lipid vesicles, a charged therapeutic agent, and a destabilizing agent to form a mixture of preformed vesicles and therapeutic agent in a destabilizing solvent. The destabilizing solvent is effective to destabilize the membrane of the preformed lipid vesicles without disrupting the vesicles. The resulting mixture is incubated for a period of time sufficient to allow the encapsulation of the therapeutic agent within the preformed lipid vesicles. The destabilizing agent is then removed to yield fully lipid-encapsulated therapeutic agent particles. The preformed lipid vesicles comprise a charged lipid which has a charge which is opposite to the charge of the charged therapeutic agent and a modified lipid having a steric barrier moiety for control of aggregation.
