Abstract: An authenticable digital code includes a printable medium, a machine-readable digital code, formed on the printable medium, that graphically represent information, and at least one security signature positioned relative to the machine-readable digital code. The security signature includes a fluorescent material that, when excited by light of a first wavelength, fluoresces and emits light at a second wavelength that is different from the first wave length. Authenticity of the authenticable digital code is determined by detecting, when the authenticable digital code is illuminated by light of the first wavelength, light of the second wavelength at a position relative to the machine-readable digital code.

Abstract: A method and system for authenticating computer nodes on a network, including providing a synchronized clock system, at a predetermined clock frequency, for use with an electronic system with a plurality of system nodes. Matching counters are connected to each of the plurality of system nodes, each of the counters being incremented in accordance with the clock frequency experienced by the system nodes to which the counters are connected. A difference is calculated between a count number at the end of a certain interval and the count number for the same counter at the beginning of the interval, to arrive at a count difference for each counter. The count difference of a particular counter is compared with the count difference of at least two other counters and, in the event that the count difference of the particular counter does not match, that node is noticed as an imposter.

Abstract: A data encryption method performed with ring arithmetic operations wherein a modulus C is be chosen of the form 2w?L, wherein C is a w-bit number and L is a low Hamming weight odd integer less than 2(w?1)/2. And in some of those embodiments, the residue mod C is calculated via several steps. P is split into 2 w-bit words H1 and L1. S1 is calculated as equal to L1+(H12x1)+(H12x2)+ . . . +(H12xk)+H1. S1 is split into two w-bit words H2 and L2. S2 is computed as being equal to L2+(H22x1)+(H22x2)+ . . . +(H22xk)+H2. S3 is computed as being equal to S2+(2x1+ . . . +2xk+1). And the residue is determined by comparing S3 to 2w. If S3<2w, then the residue equals S2. If S3?2w, then the residue equals S3?2w.
