  • Patent number: 11716196
    Abstract: A secure multi-party computation implements real number arithmetic using modular integer representation on the backend. As part of the implementation, a secret shared value jointly stored by multiple parties in a first modular representation is cast into a second modular representation having a larger most significant bit. The parties use a secret shared masking value in the first representation, the range of which is divided into two halves, to mask and reveal a sum of the secret shared value and the secret shared masking value. The parties use a secret shared bit that identifies the half of the range that contains the masking value, along with the sum to collaboratively construct a set of secret shares representing the secret shared value in the second modular format. In contrast with previous work, the disclosed solution eliminates a non-zero probability of error without sacrificing efficiency or security.

With the data receiver choosing a partition or a QAP, [n, k, C], a public key Keypub=(VQen, Gen?) and a private key Keypriv=†P† are produced, where VQen is the product of an n-qubit permutation V and an n-qubit encoding operator Qen, Gen? an error generator randomly provides a dressed operator ?=V†EV spinor error E of [n, k, C]. Then, by Keypub, the sender can encode his k-qubit plaintext Ix) into an n-qubit ciphertext |?en, which is transmitted to the cloud. The receiver prepares the instruction of encoded computation Uen=PV†Qen† for a given k-qubit action M and sends to cloud, where is the error-correction operator of [n, k, C], =I2n?k?M the tensor product of the (n?k)-qubit identity I2n?k and M , and V†Q†en and P the complex-transposes of VQen and †P† respectively.

  • Patent number: 11706209
    Abstract: A system and method for granting access to network resources through access credentials given to an agent process running on each computer or machine where resource requesters reside. The system extends a traditional token-granting authorization system to the agent processes, where each agent has administrative access to machine information. The agent uses that access to acquire detailed information about resource requesters. Requester qualifications defined by the system limit requester access to resources, and are enforced both by the agent and by the central system on the network resource server. Resource requesters ask for a token for resource use from the agent, not the central system. The agent uses its credentials to get a token from the central system and then return the token to qualified requesters.

    Abstract: A method for preventing a differential cryptanalysis attack is provided. The method is implemented by an adaptive scan chain, a control module, and a plaintext analysis module. The plaintext analysis module controls the adaptive scan chain, so that two plaintexts differing in the last bit of only one byte are input through scan chains with different structures. Consequently, the two input plaintexts for which differential cryptanalysis attack technology originally can be used to crack the key are unable to generate outputs that can be used by the differential cryptanalysis attack technology.

  • Patent number: 11509458
    Abstract: A method and system for securely replicating encrypted deduplicated storages. Specifically, the method and system disclosed herein entail the replication and migration of encrypted data between storage systems that support deduplication. More specifically, a first encrypted data, which may have been encrypted using a first public cryptographic key and consolidated on a source storage system, may be translated into an interim (yet still encrypted) state using a first split private cryptographic key. Thereafter, using a compound conversion key, the interim state data may be further translated into a second encrypted data, which may be characterized as being encrypted by a second public cryptographic key. Therefore, substantively, the method and system disclosed herein may be directed to the translation of encrypted data from one encryption scheme to another while in-flight from a source storage system to a target storage system.

  • Patent number: 11496892
    Abstract: A secure infrastructure onboarding system includes an infrastructure device with an infrastructure device wireless subsystem that it may use to perform wireless key management system discovery operations in response to initialization. A key management system includes a key management system wireless subsystem it uses to perform the wireless key management system discovery operations with the infrastructure device. The key management subsystem may then wirelessly receive an infrastructure device certificate along with an infrastructure device validation key from the infrastructure device, and validate the first infrastructure device based on the first infrastructure device certificate and the first infrastructure device validation key. In response, the key management system may wirelessly transmit a first credential generation key that is configured for use by the first infrastructure device to generate first authentication credentials.

  • Patent number: 11489675
    Abstract: A computing system for generating tamper-proof electronic messages is disclosed herein. A service provider application receives an electronic message from a client application. The electronic message comprises an authorization provider (AuP) token that includes a public key of a local signing authority (LSA) and a signed payload that has been signed by the LSA using a private key of the LSA that forms a cryptographic key pair with the public key, the signed payload comprising an indication of a programmatic task to be executed by the service provider application. Responsive to validating the AuP token in the electronic message, the service provider application extracts the public key from the electronic message. Responsive to validating the signed payload based upon the extracted public key of the LSA, the service provider application executes the programmatic task.

  • Patent number: 11481852
    Abstract: A system for generating and applying a secure token in a resource distribution network is provided. For example, a headend system generates a global token based on a time duration specified for multiple meters that are in communication with the headend system through at least a mesh network in a normal condition. The global token is associated with the time duration and is applicable to the multiple meters. The headend system causes the global token to be broadcast via a broadcast network. After receiving the global token, the meter verifies the global token and determines the time duration associated with the global token. The meter further connects premises associated with the meter to a resource distribution network for at least the time duration associated with the global token.

  • Patent number: 11461435
    Abstract: Techniques, for secure processing of encrypted data on public resources, include receiving first data indicating a sequence of reversible q-bit gates including a first segment for decrypting, a second segment for operating on the decrypted data, and a third segment for encrypting the resulting data. Second data indicates rules for replacing a first sequence of two gates operating on at least one shared bit of an input N-bit word with a different second sequence of one or more gates that produce the same output N-bit word. The second data is used to propagate: a gate from the first segment a distance into the second segment or beyond; and, a gate from the third segment a distance into the second segment or before. This produces an obfuscated sequence of reversible gates. Obfuscated instructions based on the obfuscated sequence of gates are sent to the public resources.
