  • Patent number: 11314518
    Abstract: A method of monitoring execution in an execution environment of an operation, for example a cryptographic operation, comprising a sequence of instructions, is disclosed. Instructions sent in the sequence from a main processor to one or more auxiliary processors, for example cryptographic processors, to execute the operation are monitored and the sequence of instructions is verified using verification information. The method comprises enabling output from the execution environment of a result of the operation in response to a successful verification of the sequence, or generating a verification failure signal in response to a failed verification of the sequence.

  • Patent number: 11261262
    Abstract: The invention provides heterodimer bispecific antigen-binding molecules that include a first polypeptide that does not include an IgG CH1 domain and a second polypeptide where there is at least one mutation in the IgG CH3 domain that abolishes the ability of the second polypeptide to bind CH3-specific affinity media such that the first and second polypeptides have different affinities with respect to CH1 and CH3 specific affinity reagents that allows rapid isolation by differential binding. The invention also provides bispecific antibodies that have CH1 and CH3 regions with different affinities with respect to affinity reagents that allows rapid isolation by differential binding. The invention also concerns bispecific antibodies which are heterodimers of two IgG heavy chains that differ by at least two amino acids that allow for rapid isolation based on a differential affinity of one mutated heavy chain and a second mutated heavy chain toward two different affinity reagents.

  • Patent number: 11018847
    Abstract: A method to protect a device key in a device comprising at least one secure element locally connected to at least one time programmable memory storing a global value in form of a bit string comprising locked bits and unlocked bits. The locked bits are irreversibly pre-programmed in the one-time-programmable memory during an initialization phase of the device while the un-locked bits remaining in an initial state may be programmable by the secure element. The secure element is configured to generate, at initialization of the device, a device specific value by using the global value, program the device specific value previously obtained in the one time programmable memory, and erase the global value by programming the unlocked bits of the corresponding bit string. A further object of the disclosure includes a device configured to carry out the method.

    Abstract: The present invention is related to antibodies directed to the antigen CD3 and uses of such antibodies. In particular, the present invention provides fully human monoclonal antibodies directed to CD3. Nucleotide sequences encoding, and amino acid sequences comprising, heavy and light chain immunoglobulin molecules, particularly sequences corresponding to contiguous heavy and light chain sequences spanning the framework regions and/or complementarity determining regions (CDR's), specifically from FRI through FR4 or CDRI through CDR3, are provided. Hybridomas or other cell lines expressing such immunoglobulin molecules and monoclonal antibodies are also provided.

  • Publication number: 20200344075
    Abstract: Methods and devices in accordance with the disclosure relate to the secure provision of one or more keys or key pairs to protect secret data for, or associated, with a computing device. The device is typically a computing device with at least one processor or processing module configured for executing one or more applications using the secret data. The present disclosure ensures secure key provisioning by ensuring that each key in a key pair, or at least one key among a plurality of keys is associated with a device or hardware module that is distinct to the device(s) or hardware module associated with the other or remaining keys. For asymmetric key provisioning, this relates to utilizing digital signatures verified by separate devices. For symmetric key provisioning, this relates to utilizing a secret key derivation function that will operates with secret seeds that are input from two separate sources.

  • Patent number: 10597465
    Abstract: The invention provides novel bispecific monoclonal antibodies carrying a different specificity for each binding site of the immunoglobulin molecule and methods for producing novel bispecific monoclonal antibodies carrying a different specificity for each binding site of the immunoglobulin molecule. The antibodies are composed of a single heavy chain and two different light chains, one containing a Kappa constant domain and the other of a Lambda constant domain. The invention provides methods for the isolation of antibodies of different specificities but sharing a common heavy chain. The invention also provides methods for the controlled co-expression of two light chains and a single heavy chain leading to the assembly of monospecific and bispecific antibodies.
