A secure computing device having a storage arrangement configured to store a secret. The secure computing device includes a first interface configured to control a display, and a second interface configured to receive an input signal having information which reproduces a prompt to display the secret. The secure computing device is designed to read the secret from the storage arrangement on the basis of the input signal, and to control the display via the first interface in such a way that a display of the secret is effected.

Secure computing device

A method comprises generating a signed blockchain transaction using a secure computing device arranged in a local area, and an apparatus set up for short-range communication. The method comprises associating the signed blockchain transactions with the local area, wherein the signed blockchain transaction indicates a presence of the apparatus in the local area.

System and method using a locally referenced blockchain

An electronic apparatus having a memory arrangement, which is configured to store a plurality of sets of private-key material, and a data processor, which is configured to sign a message in accordance with two or more sets of private-key material from the plurality of sets of private-key material.

Electronic apparatus and method for signing a message

According to one embodiment, a processing device for multiplying a first polynomial with a second polynomial is described including a first memory storing a representation of the first polynomial, a controller configured to separate the first polynomial into parts, a second memory storing pre-determined results of the multiplications of the second polynomial with possible forms of the parts of the first polynomial, a third memory for storing the result of the multiplication, an address logic, configured to determine, for each part of the first polynomial, a start address of a memory block of the second memory based on the form of the part and the location of the part within the first polynomial and an adder configured to add, for each determined address of the memory block of the second memory, the content of the memory block of the second memory at least partially to the contents of the third memory, wherein the data element of the third memory to which the content of a data element of the memory block of the second memory is added is the same for a plurality of the parts of the first polynomial.
