DATA ENCRYPTION METHOD Russian patent published in 2019 - IPC H04L9/06 G06F15/80 

FIELD: computer equipment.

SUBSTANCE: invention relates to the computer equipment. Encryption method of s messages m₁, m₂, ..., m_s presented in binary form and having length equal to 128 bits each, where s=t⋅n, wherein t, n are natural numbers, realized by a computer system having a processor with a SIMD architecture, consisting in that u=0; (A) is calculated in parallel using the processor SIMD instructions values c_ut+1, c_ut+2, c_ut+3, ..., c_ut+t∈V₁₂₈; performing RSHIFT₄ conversions of V₈→V₈ type, CMPR conversion of V₈×V₈→V₈ type and conversion BLEND of V₈×V₈×V₈→V₈ type; transformations T₂, T₃, T₄ of V₄→V₄ type and conversion α₀, α₁, T₁, T₅, T₆ of V₄→V₈ type is calculated by loading data from auxiliary tables containing vectors of values of these transformations; conversions MULT_148.0, MULT_148.1, MULT_195.0, MULT_195.1 of V₄→V₈ type is calculated by loading data from auxiliary tables containing vectors of values of these transformations; calculating u=u+1; if u<n, then proceeding to step (A); obtaining encrypted messages c_i, i=1, 2, …, s.

EFFECT: high efficiency of the encryption process.
