Samsung Electronics is bolstering its security measures to counter emerging threats.

The South Korean technology giant has revealed that Samsung System LSI has developed the mobile industry’s first-ever security chip, called S3SSE2A, which features hardware post-quantum cryptography (PQC). A significant threat to data security is posed by quantum computers, which possess unparalleled computational speed and the capability to compromise existing security systems.

By 2030, quantum computers are expected to become commercially available, putting existing security systems, which rely on public-key cryptography, at risk of easy decryption. As a result, new post-quantum cryptography solutions will be necessary.

Samsung’s new S3SSE2A chip provides hardware post-quantum cryptography, safeguarding critical phone data from quantum computing threats that could potentially render existing security systems ineffective as early as 2028.

Initially, Samsung stated that the newly launched Galaxy S25 is the first phone with PQC capabilities, courtesy of the Snapdragon 8 Elite chip. However, Samsung LSI now claims that the S3SSE2A chipset is the industry’s first to offer hardware post-quantum cryptography, without mentioning the Galaxy S25 or the Snapdragon 8 Elite in its announcement, leaving uncertainty about whether the Galaxy S25 has a PQC solution.
