+ - SPARC accuses SparkFun for trademark infringement->

Submitted by isnoop
isnoop (239143) writes "SparkFun.com, an electronic components distributor has received a cease and desist letter from SPARC International, Inc. claiming "Because the dominant portion of the SparkFun mark, namely, SPARK, is phonetically identical and nearly visually identical to SI's SPARC mark, and because it is used in connection with identical goods, we believe confusion is likely to occur among the relevant purchasing group.""

Encryption

+ - Cryptographic Key Rotation Solutions?->

Submitted by

isnoop writes "As part of a search for an ideal key-rotation approach, I've begun to wonder if there is an encryption method that would allow generation of more than one key that can be used to decrypt the same encrypted string. That key could then be split in two between the data storage machine and the data requesters, with the power on the side of the storage machine to revoke its half of the key at any time. This way, multiple keys could be used and revoked, but the underlying data would never have to be re-encrypted.

One possible solution could be a public/private key algorithm where multiple public keys can be generated for the same private key. The public keys could then be split and used as described.

Does anyone have any experience with this sort of problem or know an encryption method that might fit this description?"
