International Classification:

H04L 9/08
H04L 9/00

US Classification:

380278, 380 44

Abstract:

Methods and systems for transferring information to a device include assigning a unique identifier to a device and generating a unique key for the device. The device is located at a first site, and the unique identifier is sent from the device to a second site. The unique key is obtained at the second site, and it is used for encrypting information at the second site. The encrypted information is sent from the second site to the device, where it can then be decrypted.

International Classification:

H04L 29/06

US Classification:

713156

Abstract:

A system and method for transferring information include generating a public/private key pair for programming equipment and sending the programming equipment public key to a certificate authority. A programming equipment certificate is generated using the programming equipment public key and a private key of the certificate authority. The programming equipment certificate and a certificate authority certificate are sent to the programming equipment. Information is transferred to or from the programming equipment in response to an authentication using the programming equipment certificate and the certificate authority certificate.

US Classification:

726 27, 713100

Abstract:

According to an embodiment, a programmable logic device includes a plurality of logic blocks, memory, a plurality of connection control elements and a logic unit. The logic blocks are grouped into one or more programmed partitions. The memory stores authentication information and partition information. The connection control elements controllably interconnect different ones of the logic blocks. The logic unit controls external access to the one or more partitions based on the authentication information, controls reprogramming of the one or more partitions based on at least some of the partition information and configures the connection control elements based on at least some of the partition information.
