How a quantum computer could break 2048-bit RSA encryption in 8 hours
  • To send secure messages, current computers use the RSA (Rivest-Shamir-Adleman) encryption code that uses numbers that are at least 2048 bits long.
  • These codes are undecipherable by conventional computers, but it is believed that quantum computers could decipher these codes in the coming years.
  • In this regard, a study indicates that with recent algorithms, quantum computers with a capacity of 20 million qubits can decode numbers of more than 2048 bits in 8 hours.
  • Even though it is not yet known when a computer of this type will be ready, organizations that need to safeguard documents for the next 25 years are worried.
  • In particular, the possibility of deciphering the security codes disturbs governments, banks, and military institutions that need to protect secret data.
