system and method , for secure data transmission, which includes generating a hash key using a character string and a private key

摘要

A system (10) for secure data transmission comprises a processor (30), a memory (32) coupled to the processor (30), and a string generator (40) stored in the memory (32) and executable by the processor (30). The string generator (40) is adapted to generate a character string (54). The system (10) also comprises a hashing engine (42) stored in the memory (32) and executable by the processor (30). The hashing engine (42) is adapted to generate a hash key (64) using the character string (54) and a private key (62). The system (10) further comprises an encryption engine (44) stored in the memory (32) and executable by the processor (30). The encryption engine (44) is adapted to encrypt the data (70) using the hash key (64). The processor (30) is adapted to transmit the encrypted data (72), an identification key (60) related to the private key (62), and the character string (54) to a recipient (16).
