The phrase "cryptographic schemes" is correct and usable in written English.
It is a term used to describe any kind of algorithm or process used to secure data and communications. For example, "The company implemented new cryptographic schemes to ensure the security of their customer data."
Cryptographers have constructed several cryptographic schemes of this sort by starting with a "hard" mathematical problem such as factoring a number that is the product of two very large primes and attempting to make the cryptanalysis of the scheme be equivalent to solving the hard problem.
Of course, the application of cryptographically strong ciphers does prevent unwanted attacks against possibly weak cryptographic schemes - in this sense, EEFB and SBE are unrivalled in terms of security.
Others are working on quantum cryptographic schemes to replace existing schemes in case a practical device is built.
Many common cryptographic schemes rely on the fact that this is hard for a conventional computer to do.
These papers build cryptographic schemes making use of various properties of pairings.
All elliptic curve cryptographic schemes are based on scalar multiplication of points, and hence its faster computation signifies faster operation.
Theorists quickly proved that ideal obfuscation would enable almost any cryptographic scheme that they could dream up.
An effective and innovative cryptographic scheme compared to the existing works is proposed here.
Hence it is essential to have an efficient cryptographic scheme to protect the communications done in WSNs.
To avoid cryptographic devices suffering from related-key attacks, it is necessary to design a cryptographic scheme that resists against such attacks.
The first government election to use a new cryptographic scheme that lets both voters and auditors check that votes were cast and recorded accurately will be held tomorrow in Takoma Park, MD.
