Security Parallels between People and Pervasive Devices
Unique and challenging security problems arise due to the scarcity of computational, storage, and power resources in the low-cost pervasive computing environment. Particularly relevant examples of resource-constrained systems are low-cost Radio Frequency Identification (RFID) systems. Surprisingly, the computational abilities of low-cost pervasive devices like RFID tags are similar to another pervasive, weak computing "device": people. Neither low-cost pervasive devices nor people can efficiently perform public-key or even symmetric cryptographic operations. Neither can store long random strings nor devote too much time or energy to security protocols. Both may need to authenticate themselves over a public channel to an untrusted terminal, without any outside help or external devices. Because of these similarities, pervasive security may benefit by adapting techniques from humancomputer security, or vice versa. This article treats RFID tags as a model for other lowcost perva...
