Pre-mRNA introns as a model for cryptographic algorithm: theory and experiment
No full textThe RNA-Crypto System (shortly RCS) is a symmetric key algorithm to cipher data. This algorithm, as
shown below, has the peculiarity to expand the message to be encrypted hiding the ciphered message itself
within a set of garbage and control information.
The idea for this new algorithm starts from the observation of nature. In particular from the observation
of RNA behavior and some of its properties.
In particular the RNA sequences has some sections called Introns. Introns, derived from the term
"intragenic regions", are non-coding sections of precursor mRNA (pre{mRNA) or other RNAs, that are
removed (spliced out of the RNA) before the mature RNA is formed. Once the introns have been spliced out
of a pre-mRNA, the resulting mRNA sequence is ready to be translated into a protein. The corresponding
parts of a gene are known as introns as well.
The nature and the role of Introns in the pre-mRNA is not clear and it is under ponderous researches
by Biologists but, in our case, we will use the presence of Introns, in the RNA-Crypto System output, as a
strong method to add only apparently chaotic and non coding information with an unnecessary behavior in
the access to the secret key to code the messages.
In the RNA-Crypto System algorithm the introns are sections of the ciphered message with non{coding
information as well as in the precursor mRNA. But the term "non{coding" does not necessarily mean "junk
data".

A Residential Electric Load Simulator to Support Demand Management Strategies in Competitive Electricity Markets
No full textA low-cost IoT solution for power availability improvement in hospitals
Full text linkPower is a crucial element in hospitals whether it's within the intensive care units, surgical bays, or medical scanning rooms. Without reliable power, patients’ lives are at risk. The power availability improvement is therefore a crucial point in healthcare. A supervising system superimposed to the main components of the power system as able to promptly signal anomalies or malfunctioning or outages can be very useful for this task. To this aim, an Internet of Things (IoT) based solution has been implemented that allows equip at low cost the various electrical components in the distribution MV/LV substations of the hospital’s power system so as to be connected to a central supervising system. The solution implements a platform based on Rapsberry pi 3
Conjugation as public key agreement protocol in mobile cryptography
No full textWe analyze a key agreement algorithm realization, not using Diffie-Hellman approach, but using matrix powers and conjugation. Introduced in a theoretical frame by Sakalauskas et. al. in 2007, it is here implemented in J2ME on mobile devices (Nokia N70 equipped with Symbian S60 operating system). We study its appli-ability and performances and compare them with Elliptic Curve and standard Diffie-Hellman Bouncy Castle implementation, freely available on the web
Analysis of residential standby power demand control through a psychological model of demand
No full textStandby energy is actually one of the largest electrical end use with the largest potential energy savings in the residential sector. In the paper, a model of the residential customer's demand using a bottom-up approach, implemented in a load simulator, has been used in order to evaluate the impact of standby end users on Italian average households' daily load shape. Finally, some more diffuse standby power demand management options have been simulated thus allowing predict possible impacts directly on daily load shape
