Improved Differential Cryptanalysis of CAST-128 and CAST-256

2008 IEEE Region 8 International Conference on Computational Technologies in Electrical and Electronics Engineering, 2017
CAST-128 and CAST-256 are two symmetric algorithms designed by Adams in 1990s. Both of them adopt the CAST design procedure which makes them process a number of desirable cryptographic. CAST-128 is notably used as the default cipher in some versions of GNU Privacy Guard (GPG) and Pretty Good Privacy (PGP) systems.

Caste differentiation in Cardiocondyla obscurior

2021
In ants reproductive division of labor is a key feature of eusociality and is facilitated by the development of morphological distinct castes. In the myrmicine ant Cardiocondyla obscurior queens monopolize reproduction while workers are sterile and have no reproductive power.

A toolkit for caste differentiation

Nature Ecology & Evolution, 2018
The identification of a set of conserved genes that has had stable expression patterns over 120 million years of ant evolution provides a glimpse into the mechanisms that generate queen and worker castes in ants.

Differential Power Analysis of CAST-128

2010 IEEE Computer Society Annual Symposium on VLSI, 2010
Power analysis is used to reveal the secret key of security devices by monitoring the power consumption of certain cryptographic algorithm operations through a statistical analysis approach known as Differential Power Analysis (DPA). Whilst this has been applied extensively to attacks on FPGA devices, there has been little research into attacks on ASIC

CASTE DIFFERENTIATION AMONG TERMITES

Transactions of the Royal Society of South Africa, 1954
The development of the five castes found in the nests of Amitermes atlanticus Fuller is described in this paper, together with some notes on the nasute soldier caste of Trinervitermes gemellus Sjostedt. The investigations, carried out over a period of five years, lead to the conclusion that all newly hatched termites inherit the potentiality of growing
