G06F2207/7233 - CPC Classification

Classification description:

Indexing scheme relating to methods or arrangements for processing data by operating upon the order or content of the data handled; Indexing scheme relating to groups -; Countermeasures against side channel or fault attacks; Randomisation as countermeasure against side channel attacks Masking, e.g. (A**e)+r mod n

Sub-classes:

G06F2207/7238 » Operand masking, i.e. message blinding, e.g. (A+r)**e mod n; k.(P+R) 27
G06F2207/7242 » Exponent masking, i.e. key masking, e.g. A**(e+r) mod n; (k+r).P 29
G06F2207/7247 » Modulo masking, e.g. A**e mod (n*r) 5
