Samsung has created the first mobile chip to protect against quantum threats

Samsung has unveiled the mobile industry's first security chip with hardware post-quantum cryptography (PQC).

Here's What We Know

The new chip, dubbed S3SSE2A, was announced on 25 February and is designed to protect critical data on smartphones from quantum computing threats. Quantum computers, which could become commercially available after 2030, are capable of cracking existing security systems based on public-key cryptography. Therefore, these systems could become powerless as early as 2028.

Samsung's new S3SSE2A chip offers hardware-based post-quantum cryptography to protect the data on the phone from such threats. In January, Samsung's mobile division said that the Galaxy S25 would be the first phone with PQC capabilities thanks to the Snapdragon 8 Elite chip. However, in Samsung's latest announcement, LSI did not mention the Galaxy S25 or Snapdragon 8 Elite, which leaves the question of what PQC solution the Galaxy S25 uses and whether it is related to the S3SSE2A chip.
