20210184830 | SWAPPING OF ENCRYPTION AND DECRYPTION OPERATIONS FOR SIDE CHANNEL ATTACK PROTECTION - This disclosure describes systems on a chip (SOCs) that prevent side channel attacks (SCAs). The SoCs of this disclosure concurrently operate multi-round encryption and decryption datapaths according to a combined sequence of encryption rounds and decryption rounds. An example SoC of this disclosure includes an engine configured to encrypt transmission (Tx) channel data using a multi-round encryption datapath, and to decrypt encrypted received (Rx) channel data using a multi-round decryption datapath. The SoC further includes a security processor configured to multiplex the multi-round encryption datapath against the multi-round decryption datapath on a round-by-round basis to generate a mixed sequence of encryption rounds and decryption rounds, and to control the engine to encrypt the Tx channel data and decrypt the encrypted Rx channel data according to the mixed sequence of encryption rounds and decryption rounds. | 2021-06-17 |
20210184831 | OBFUSCATING CRYPTOGRAPHIC PARAMETERS USED IN ELLIPTICAL CURVE CRYPTOGRAPHY, AND RELATED SYSTEMS AND DEVICES - An obfuscation process is described for obfuscating a cryptographic parameter of cryptographic operations such as calculations used in elliptical curve cryptography and elliptical curve point multiplication. Such obfuscation processes may be used for obfuscating device characteristics that might otherwise disclose information about the cryptographic parameter, cryptographic operations or a cryptographic operations more generally, such as information sometimes gleaned from side channel attacks and lattice attacks. | 2021-06-17 |
20210184832 | MULTI-KEY ENCRYPTION AND DECRYPTION FOR SIDE CHANNEL ATTACK PREVENTION - This disclosure describes systems on a chip (SOCs) that prevent side channel attacks (SCAs). An example SoC includes an encryption engine, a key store, and a security processor. The key store is configured to store a plurality of encryption keys. The encryption engine is configured to encrypt transmit (Tx) channel data using any encryption key of the plurality of encryption keys stored to the key store. The security processor is configured to activate SCA mitigation logic of the SoC based on a determination that the encryption engine encrypts the Tx channel data using a strong key selected from the plurality of encryption keys stored to the key store, and to operate the SCA mitigation logic in a deactivated state based on a determination that the encryption engine encrypts the Tx channel data using a weak key selected from the plurality of encryption keys stored to the key store. | 2021-06-17 |
20210184833 | BLOCKCHAIN TRANSACTION MANAGER - A blockchain transaction manager implements a method of managing submission of blockchain transactions to a node in a blockchain network by validating a received blockchain transaction and enqueuing the validated received blockchain transaction in a transaction queue, preparing at least one transaction attribute of the received blockchain transaction and placing the received blockchain transaction in a persistence queue, digitally signing or certifying the received blockchain transaction, attempting to submit the digitally signed or certified blockchain transaction to the node, and polling a blockchain status of the submitted blockchain transaction. Processes are provided for automatically recalculating blockchain transaction processing fees in the blockchain transaction attributes. Processes are also provided for repairing transaction attributes when the blockchain transaction has been rejected and submitting the repaired blockchain transaction to the node. Also, nonces are automatically assigned to received blockchain transactions and reassigned when the associated blockchain transaction has been rejected. | 2021-06-17 |
20210184834 | RING CHAIN ARCHITECTURE - A system stores transaction data in a ring chain architecture. A ring chain comprises blocks of data stored as a length-limited block chain in a ring buffer configuration. A block of transactions is stored on a ring chain until enough new blocks are added to overwrite the ring buffer with new blocks. The system stores multiple ring chains that update at varying frequencies. A new block on a lower frequency ring chain stores an aggregation of data from the blocks that were added to a higher frequency ring chain in the time since the previous addition of a block to the lower frequency ring chain. Thus, a system of ring chains stores progressively summarized state transition data over progressively longer time intervals while maintaining immutability of the record and reducing storage requirements. | 2021-06-17 |
20210184835 | PRIVACY TRANSACTION PROCESSING METHOD, ELECTRONIC DEVICE AND STORAGE MEDIUM - Embodiments of the present disclosure provide a privacy transaction processing method, an electronic device and a storage medium, and relates to a field of blockchain technologies. The method includes: obtaining a business transaction request to be executed; if the business transaction request is a privacy business transaction request, obtaining a corresponding privacy key, in which the privacy key is an organization privacy key of a privacy organization to which the privacy business transaction request belongs; decrypting and executing the privacy business transaction request according to the privacy key to generate privacy business transaction data, in which the privacy business transaction data comprises at least associated information of privacy content data and the privacy business transaction request; and storing the privacy business transaction data in a blockchain, and storing the privacy content data locally. | 2021-06-17 |
