Method for accelerating cryptographic calculations in cloud computing, involves providing encrypted coded message with information, and utilizing calculation server for performing encrypted coding of message during application phase

摘要

The method involves performing encrypted coding of a message (M) by an electronic device (MOB1) e.g. personal digital assistant, where the encrypted coded message is provided with information from the electronic device. A calculation server (CALC S) is utilized for performing encrypted coding of the message during an application phase. The encrypted coded message is arranged with a signature that is read by the calculation server. The signature is checked by the calculation server for allowing decrypting of the encrypted coded message. Independent claims are also included for the following: (1) a computer program comprising instructions for performing a method for accelerating cryptographic calculations (2) a system for accelerating cryptographic calculations.
