Cabinet security – In the Homecare

operation Cabinet and key holderRFID are used in all key holderThe system is automatically identifying the ID of the key

(even if you put it in the wrong position)!All non present keys can be presented with:

The User nameThe Time of pickupWhen it should be backand related information.

The administrator can assign new and temporary users!Access by RFID-transponder and/or personal code.The log is active all the time.Can be combined with several other cabinets and draws

in local or wide area network!WEB-interface for easy setup and use!

RFID – IN MEDICAL CAREIn the Box of medicals

RFID-system for identification of each stored objects.

Some important questions:

What object did they take out?What is the weight of a tablet?Did they take to little or to much?What object is about to run out of storage?Have I taken the medicine at the right time?Did I take it at all?Am I the right person tempering with the

medical box?

The Medical box is produced at this time

Stream Ciphers: Are They Really Needed?

Elena DubrovaRoyal Institute of Technology

Stockholm, Sweden

Block ciphers vs. stream ciphers

Block ciphers operate with a fixed transformation on large blocks of plaintext data

Stream ciphers operate with a time-varying transformation on individual plaintext bits• Keystream

• generator

+

• secret key

• initial value • keystream

• ciphertext• plaintext

Reasons to prefer block ciphers today

Very Availability of standardized schemes

More versatile building clockBetter understanding of security issuesBetter covered in textbooks and

courses Smaller area and powerHigher encryption speedSimpler protocols for handling small or

variable sized inputsZero error-propagation

Very small area and power

Constrained environments applications: Very small battery powered devices e.g. RFID

RFIDs are likely to become a very important and successful technology in the next decade

Low-cost RFID can only spare a few hundreds of gates for security functionality (Juels, 2006)

Stream ciphers can efficiently combine encryption and authentication algorithms

Important next steps for stream ciphers: Standardization Better understanding of security issues Better coverage in textbooks and courses

Topics Covered

Homecare Tools for disable people Interest in sustainable system solutions Usage of standard systems in local government
