20100325428 | System and Method for Authentication of a Hardware Token - A method for authentication. A computer obtains a random number R generated by a hardware token. The computer forms and returns to the hardware token a signature Ck′(R) formed using the random number R with a computer secret key Ck′. The computer receiving from the hardware token authentication of the signature Ck′(R) that is performed by the hardware token using a computer public key Ck stored in the hardware token. | 12-23-2010 |
20110145573 | SYSTEM FOR SECURE PACKET COMMUNICATION - A system for processing a communication data item. The communication data item is divided into at least two unencrypted packets to be encrypted. Each encrypted packet is generated from a corresponding unencrypted packet. Each unencrypted packet has a packet header and plaintext data. The packet header has an identifier field that includes a packet identifier that is identical for all unencrypted packets. Generating an encrypted packet for each unencrypted packet includes: determining a vector identifier from the identical packet identifier, wherein the vector identifier is associated with the identical packet identifier; ascertaining an initial vector from the vector identifier; and forming an encrypted packet header by inserting the vector identifier into a first portion of the packet header and encrypting a second portion of the packet header through use of the initial vector. The encrypted packets are subsequently decrypted and combined to reconstruct the communication data item. | 06-16-2011 |
