Title:
ENCRYPTION COMMUNICATION SYSTEM, ENCRYPTION COMMUNICATION METHOD, PROGRAM
Document Type and Number:
Japanese Patent JP2015126332
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide an encryption communication system for realizing a RKA-KDM-CCA secure public key encryption method.SOLUTION: The encryption communication system includes a parameter device, a key generation device, an encryption device, and a decryption device. The parameter device outputs a condition parameter and a common parameter. The key generation device outputs a secret key and a public key with the common parameter as an input. The encryption device outputs an encrypted text with the common parameter, the public key, and a message as inputs. The decryption device outputs a rejection symbol or a message with the common parameter, an interpolation secret key, and the encrypted text as inputs.
