RC2: Day 9

Day 9: Topic Models

On the Design and Security of RC2

The block cipher RC2 was designed in 1989 by Ron Rivest for RSA Data Security Inc. In this paper we describe both the cipher and preliminary attempts to use both differential and linear cryptanalysis.

RC2 - A Living Lab for Cloud Computing

In this paper we present our experience in building the Research Compute Cloud (RC2), a cloud computing platform for use by the worldwide IBM Research community. Within eleven months of its official release RC2 has reached a community of 631 users spanning 34 countries, and serves on average 350 active users and 1800 active VM instances per month. Besides offering a utility computing platform a...

On the Ratio of Photosynthetic Reaction Centers RC2/RC1 in Chlorella.

Chlorella pyrenoidosa (Emerson strain) was grown under high and under low irradiance. Measurements of the O(2) flash yield and the P700 absorption change gave estimates for the ratio of photoreaction centers RC2/RC1 at 1.2 to 1.5. A background light 1 did not increase flash yield.

Related-key cryptanalysis of 3-WAY, Biham-DES, CAST, DES-X, NewDES, RC2, and TEA

We present new related-key attacks on the block ciphers 3WAY, Biham-DES, CAST, DES-X, NewDES, RC2, and TEA. Differential related-key attacks allow both keys and plaintexts to be chosen with specific differences [KSW96]. Our attacks build on the original work, showing how to adapt the general attack to deal with the difficulties of the individual algorithms. We also give specific design principl...
