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 ...

Now-a-days, cloud computing is emerging technology which gives open resources on the internet. It is offering large amount of data to the users and distributed data over the network. But the main ...

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 ...

A digital signature, an asymmetric cryptography is designed using VHDL. The implementation has a Message Digest block and a RSA block. Implemented Digital Signature Algorithm on a Spartan 3 FPGA board ...

Amidst all of the confusion and concern over an encryption algorithm that may contain an NSA backdoor, RSA Security released an advisory to developer customers today noting that the algorithm is the ...

Roula Khalaf, Editor of the FT, selects her favourite stories in this weekly newsletter. Computer security experts were struggling this week to assess a startling claim by Chinese researchers that ...

A recent research paper makes the claim that the RSA cryptographic algorithm can be broken with a quantum algorithm. Skeptics warn: don’t believe everything you read. Every CISO has encryption ...

It sounds too preposterous for even James Bond: by placing a mobile phone next to a PC, researchers can “listen” to the faintest sound a CPU makes as it churns away on RSA-encoded content and extract ...
