Method and device for file encryption

TL;DR: In this article, a plurality of failed login records that correspond to failed login attempts detected by a computing system are analyzed to identify suspicious patterns of activity that can facilitate the supplementation of password blacklists for improving account security.

TL;DR: In this article, a system and a method for managing confidential data in a cloud service is described, which comprises a cryptographic key service comprising two or more cryptographic key servers, each being arranged to compute file encryption keys, kj, on the basis of information regarding data and using one or more of the cryptographic keys.

TL;DR: In this article, a data transmission method based on quantum communication, being applied to a first communication end, was revealed, which includes the steps of encrypting the target data with a first conventional key; sending the obtained first encrypted data to a second communication end; and decrypting the second encrypted data with the quantum key to obtain the conventional key set.

TL;DR: In this article, a personnel archive management method and system based on a block chain is described, and the method comprises the following steps: employing a Hash encryption algorithm to encrypt an archive of a user to generate a Hash value of the archive, and picking the content information corresponding to the Hash value; and creating archive information, encrypting the archive information throughthe public key of the user, and storing a ciphertext of the archived information into the block chain.

TL;DR: In this paper, a method of encrypting a message for message integrity is provided, in which a random number is generated, a first ciphertext is generated by encrypting the message by using the generated random number, a hash value of the first ciphers is calculated, an encryption key is generated using the hash value and a shared key, and the first and second ciphertexts are combined.

TL;DR: In this article, a system and method that secures select data in a mobile computing device and retrieves the select data at a remote server is presented, where an application is installed on the mobile computing devices which sends a periodic signal to the remote server and receives an acknowledgement signal from the remote servers indicating if the mobile device is stolen.

TL;DR: In this article, the authors describe a system for scanning an endpoint terminal across an open computer network, where a scanner engine in a computer server is used to collect data from the scanner agent across the secure connection, analyzes the collected data, and determines any updates for the endpoint terminal from the analysis.

TL;DR: In this article, a digital signature protocol generates a signature component using a hash of an encrypted message, and the signature component and encrypted message form a signature pair that is forwarded to a recipient.
