An alternative model of quantum key agreement via photon coupling
It has recently been shown that shared cryptographic quan tum bits are achievable through the use of an optical coupler instead of polarised photons We show that such shared cryptographic bits can also be produced by using a di erent optical apparatus a beam splitter An important advantage of such a system is that it could be experimentally more feasible than an optical coupler

متن کاملShared Architecture for Encryption/Decryption of AES
Security has become an increasingly important feature with the growth of electronic communication. The Symmetric in which the same key value is used in both the encryption and decryption calculations are becoming more popular. The AES algorithm is capable of using cryptographic keys of 128, 192, and 256 bits to encrypt and decrypt data in blocks of 128 bits. This standard is based on the Rijnda...
متن کاملPhysical key-protected one-time pad
We describe an encrypted communication principle that forms a secure link between two parties without electronically saving either of their keys. Instead, random cryptographic bits are kept safe within the unique mesoscopic randomness of two volumetric scattering materials. We demonstrate how a shared set of patterned optical probes can generate 10 gigabits of statistically verified randomness ...
