Abstract: In an aspect, a cache memory device receives a request to read an instruction or data associated with a memory device. The request includes a first realm identifier and a realm indicator bit, where the first realm identifier enables identification of a realm that includes one or more selected regions in the memory device. The cache memory device determines whether the first realm identifier matches a second realm identifier in a cache tag when the instruction or data is stored in the cache memory device, where the instruction or data stored in the cache memory device has been decrypted based on an ephemeral encryption key associated with the second realm identifier when the first realm identifier indicates the realm and when the realm indicator bit is enabled. The cache memory device transmits the instruction or data when the first realm identifier matches the second realm identifier.

Abstract: One feature pertains to an electronic device that includes a memory circuit and a processing circuit. The processing circuit computes a scalar multiplication output Z where Z=k·P by receiving an input multiplier k and a base P, and adds a modifier s to the input multiplier k to generate k′. The processing circuit also computes an intermediate scalar multiplication output Z′ where Z′=k′·P by using a digit expansion of k′ that includes a sequence of digits ki belonging to a digit set D. Additionally, the processing circuit subtracts s·P from Z′ to obtain the scalar multiplication output Z if k′ is odd or subtracts (s+1)·P from Z′ to obtain the scalar multiplication output Z if k′ is even. The scalar multiplier output Z may be used in a cryptographic security algorithm to secure data.

Abstract: Disclosed is a method for providing a public key for authenticating an integrated circuit. In the method, the integrated circuit obtains a hardware key and an integrated circuit identifier. The integrated circuit generates a derived key based on the hardware key using a key derivation function (KDF) shared with a manufacturing machine. The integrated circuit generates a private key and a corresponding public key using the derived key as an input to a deterministic function. The integrated circuit then provides the public key and the integrated circuit identifier to a partner service for authentication of the integrated circuit using an anonymized credential database to be provided to the partner service by a manufacturer.

Abstract: Disclosed is an apparatus and method for encrypting plaintext data. The method includes: receiving at least one plaintext data input; applying a Nonce through a function to the at least one plaintext data input to create Nonced plaintext data outputs and/or to intermediate values of a portion of an encryption function applied to the at least one plaintext data input to create intermediate Nonced data outputs; and applying the encryption function to at least one of the Nonced plaintext data outputs and/or the intermediate Nonced data outputs to create encrypted output data. The encrypted output data is then transmitted to memory.

Abstract: A method operational on a receiver device for exchanging and/or generating security keys is provided. A first encrypted master key Km is received at the receiver device from a transmitter device, the first encrypted master key Km secured by a receiver public key Kpub-rx. The first encrypted master key Km may be decrypted with a receiver private key Kpri-rx to obtain the master key Km. The master key Km may be encrypted using a block cipher that applies a receiver secret key Kh to obtain a second encrypted master key.
