The present disclosure provides an attack detection method and device for collaborative cryptographic calculation based on a change factor, which can be applied to the cryptographic field. The attack detection method includes: in response to completion of digital signature calculation, message decryption or key exchange, determining the original sub-private key D1′ and the first change factor W1; sending the first change factor W1 to the second communication party; receiving the second change factor W2 from the second communication party; using the first change factor W1 and the second change factor W2 to change the original sub-private key D1′ to obtain the current sub-private key D1; determining a partial public key P1 based on the current sub-private key D1; and in response to failure of digital signature calculation, message decryption or key exchange, sending the partial public key P1 to the second communication party so that the second communication party uses the partial public key P1 for pairing processing, and performing attack detection based on the obtained pairing result.

An information processing device determines at least one change factor between a predetermined reference data set and a verification data set different from the reference data set on the basis of the reference data set and the verification data set, and generates and outputs description information for presenting the determined change factor to a user. And performing the re-learning of the machine learning model on the basis of policy information indicating the re-learning policy set by the user on the basis of the description information.

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.

The invention discloses a password verification method and a related device, and the method comprises the steps: obtaining an identifier and a target change factor in response to a verification request from a client, and enabling the verification request to carry a first password generated by a management server; and determining a password variable corresponding to the target variation factor. And according to the identifier and the password variable, performing encryption through an encryption algorithm to obtain a plurality of second passwords. And verifying the first password and the plurality of second passwords, and if verification succeeds, establishing connection between the client and a container corresponding to the container arrangement platform. Therefore, by introducing the variation factor, the second password for verification is dynamically changed, and the possibility that the password is cracked due to the fact that the password is fixed and single is reduced. The dynamic first password and the plurality of second passwords are generated at the two ends respectively, the passwords do not need to be changed by modifying container configuration, the password generation speed and the password verification speed are higher, and the password verification safety before the client is connected with the container is improved.

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.
