The first keypair includes a public key and a private key. The method further includes a step of requesting, from a remote server configured to register and provision connected devices, a provisioning of credentials of the electronic device. The method further includes a step of verifying, by the remote server, the electronic device credentials. The method further includes a step of registering, by the remote server, the electronic device. The method further includes a step of transmitting, from the remote server to the electronic device, a device certificate. The method further includes steps of installing the transmitted device certificate within the secure element of the electronic device, and provisioning the electronic device according to the installed device certificate.

Systems and techniques for a System-on-a-Chip (SoC) security plugin are described herein. A component message may be received at an interconnect endpoint from an SoC component. The interconnect endpoint may pass the component message to a security component via a security interlink. The security component may secure the component message, using a cryptographic engine, to create a secured message. The secured message is delivered back to the interconnect endpoint via the security interlink and transmitted across the interconnect by the interconnect endpoint.

A method for searchable encryption of a system defining a secret key and a public is provided. A data stream cipher can include n elementary data (b.sub.1, b.sub.2, . . . , b.sub.n). The method can include generation of a variate for all elementary data b.sub.j, for values of j from 1 to n, generation of an element function of the public key (g.sup.x(bj),zj) and the variate, the element being associated with a random element of a group of a bilinear environment, the element associated with the random element of the group forming first encryption data (C.sub.j,1). The method can also include generation of a shift factor (g.sup.a.zj−1) function of the variate and the public key, and associated with the random element of the group, the shift factor representing a position of the monomial in the encrypted stream, the shift factor associated with the random element of the group forming second encryption data. The data stream cipher can include the first and second encryption data for all values of j from 1 to n.

An electronic device according to an embodiment includes: a camera including an image sensor; a communication module; a memory; and a processor operationally connected to the camera, the communication module, and the memory. The memory may store instructions that, when executed, instruct the processor to: acquire a first image including an external object by using the camera; acquire a second image including less information than the first image by using at least a part of the first image; transmit the second image to an external electronic device by using the communication module; receive security information corresponding to the second image from the external electronic device by using the communication module; and secure the first image, at least partially based on the security information. In addition, various other embodiments are possible.

There is provided an elliptic curve cryptographic scheme for permitting secure communications between two or more cryptographic correspondent devices, with a simple side-channel attack countermeasure.
