摘要： Technologies are generally described for providing a fully homomorphic encryption scheme. In some examples, a method performed under control of a first device may include determining an enciphering function, based at least in part on a secret key of the first device and a system parameter; enciphering a plaintext into a first ciphertext, based at least in part on the enciphering function; transmitting, to a server, the first ciphertext and the system parameter; receiving, from a second device, a second ciphertext to which the first ciphertext has been processed by the second device without deciphering the first ciphertext; and deciphering the second ciphertext, based at least in part on the system parameter and a deciphering function.

摘要： The invention relates to a signcryption scheme including a method performed under control of a sender device comprising calculating a public key of the sender device based on a system parameter, calculating a temporary public key of the sender device based on the system parameter, calculating a temporary common key of the sender device based on a temporary secret key of the sender device and a public key of a receiver device, calculating a ciphertext from a message based on the temporary common key and generating a signature of the sender device based on an intermediate parameter, the system parameter and the secret key of the sender device. The temporary secret key of the sender device, intermediate parameter and secret key of the sender device are engaged in a non-associative octonion ring. The embodiments also disclose the reversal process of decrypting the sent message carried out at the receiver device.

摘要： Technologies are generally described for providing an anonymous signature scheme. In some examples, a method performed under control of an end device ma 320 include receiving public parameters from a central system; generating an enciphering function based at least in part on the received public parameters; calculating parameters for a signature based at least in part on the generated enciphering function; and transmitting, to a verifying device, the signature that includes a message, a key of the end device and the calculated parameters for the signature.
