A method of providing a reference voltage for reading of a resistive memory array, and a read circuit for reading of a resistive memory array. The method comprises the steps of generating a first reference voltage when a bitline of the resistive memory array is in a first resistance state, and generating a second reference voltage when the bitline is in a second resistance state; wherein the first reference voltage is different from the first reference voltage and the first resistance state is different from the second resistance state.

wherein each R1 is independently an organic or hetero-organic group, each R2 is independently a substituent having molecular weight no more than about 120 Daltons, X and Z are each a sulfur-bonded species, at least one of X and Z is not hydrogen, and n is an integer greater than or equal to 1. X and Z may be hydrogen or a functional group, such as a thiol-reactive group. The reactive thiol groups of the polythioaminal may be used to attach thiol-reactive end capping species. By using water soluble or water degradable dithiols, such as polyether dithiols, water soluble polythioaminals may be made. Some such polymers may be used to deliver therapeutics with non-toxic aqueous degradation products.

Certain embodiments described herein are generally directed to deterministic load balancing of processing encapsulated encrypted data packets at a destination tunnel endpoint. In some embodiments, an IPSec component residing within a destination tunnel endpoint is configured to select a CPU core ID of a virtual CPU using a CPU selection function. In some embodiments, the IPSec component selects an SPI value corresponding to the CPU core ID. In some embodiments, the IPsec component indicates the SPI value to a source tunnel endpoint for use in establishing an in-bound security association, wherein the in-bound security association is used by the source tunnel endpoint to encrypt a data packet received from the source endpoint and destined for the destination endpoint.

Various embodiments may provide an optical sensing device based on surface plasmon resonance (SPR).

The optical sensing device may further include a second optical member arranged to receive the reflected first and second polarization light beams from the first optical member and configured to separate the reflected first and second polarization light beams in a first direction and a second direction, respectively. The optical device may additionally include a detector arrangement configured to detect the reflected first and second polarization light beams from the second optical member.

There is provided a method of generating a ciphertext. The method includes encrypting an input data to produce an encrypted data, and randomizing the encrypted data to produce the ciphertext. In particular, the randomizing process includes performing an exclusive-or (xor) operation on the encrypted data with a cipher pad, whereby the cipher pad is generated based on an xor-homomorphic function of a first key using a second key generated based on the encrypted data. There is also provided a corresponding system for generating a ciphertext, a corresponding method and system for decrypting a ciphertext, and a corresponding method and system for searching ciphertexts in a database, such as at an untrusted server.
