Many embedded systems depend on obscurity to achieve security. We often design systems to download unsigned or unencrypted firmware upgrades or store unencrypted user data, a practice we justify ...

Hot on the heels of Diffie-Hellman upending the cryptography applecart in 1976 came three more crypto newcomers that further revolutionized the field: Ron Rivest, Adi Shamir, and Leonard Adleman. The ...

Quantum computers could crack a common data encryption technique once they have a million qubits, or quantum bits. While this is still well beyond the capabilities of existing quantum computers, this ...

One of the principal challenges of resource sharing on data communication network is its security. This is premised on the fact that once there is connectivity between computers sharing some resources ...

In contrast to the cooperative preparations required for setting up private key encryption, such as secret-sharing and close coordination between sender and receiver ...

A recent, yet to be proven paper claiming to have found a way to "destroy the RSA cryptosystem" has cryptographers asking what might replace it. What if a big crack appeared overnight in the ...

RSA is dead, long live RSA! At the end of December 2022, Chinese researchers published a paper claiming that they can crack RSA encryption using current-generation quantum computing. For decades, the ...
