2 results about "Change factor" patented technology

This disclosure provides a collaborative decryption information processing method and apparatus based on a change factor, which can be applied in the field of cryptography. The method includes: in response to determining that a second communicating party has completed a decryption operation on the original information to be decrypted, determining an original sub-private key D1′ and a first change factor W1, wherein the original sub-private key D1′ is used to perform partial decryption calculations on the original information to be decrypted; sending the first change factor W1 to the second communicating party; receiving a second change factor W2 from the second communicating party; processing the original sub-private key D1′ using the first change factor W1 and the second change factor W2 to obtain a current sub-private key D1; calculating the current information to be decrypted C using the current sub-private key D1 to obtain partially decrypted information M1; and sending the partially decrypted information M1 to the second communicating party so that the second communicating party can use the partially decrypted information M1 to calculate the current information to be decrypted C to obtain the plaintext message M.

A game apparatus includes a game content effect change unit configured to change a game content effect of game content by satisfying a change factor unlocking condition, and a game element effect change unit configured to change a game element effect of a game element by satisfying a game element unlocking condition determined for each of a plurality of the game elements associated with the individual piece of game content. The game content effect change unit changes the game content effect by satisfying the change factor unlocking condition associated with a specific change factor after the game element effect of the game element associated with the specific change factor in which the game content effect is changed by the change of the game element effect reaches a specified value.
