SUB-MILLISECOND POST-QUANTUM CRYPTOGRAPHY FOR ENTERPRISE APIS.
Eliminate "Harvest Now, Decrypt Later" risks at the API boundary. Shatachandra Shield unifies an inline zero-trust policy engine with hardware-vectorized ML-KEM key encapsulation over low-latency Unix domain sockets.
Byte-exact pass across all 75 KeyGen, 75 Encaps, and 30 Decaps reference vectors.

NIST ACVP Vectors
180/180 PASSKnown-Answer Tests (KAT) validating 100% byte-exact algorithmic output against the official FIPS 203 ML-KEM reference standard.
Verified Latency & Diffusion Matrix
Measured live on native AWS EC2 Linux hardware (AVX2-optimized, Python 3.14.4, n=200 iterations).
| Parameter Set | Key Generation (mean) | Encapsulation (mean) | Decapsulation (mean) | Avalanche Bit-Flip (SAC) | NIST ACVP Vector Conformance |
|---|---|---|---|---|---|
| ML-KEM-512 | 0.2725 ms | 0.3338 ms | 0.4096 ms | 49.93% (Ciphertext, n=20) | 25 KeyGen • 25 Encaps • 10 Decaps |
| ML-KEM-768 (Standard) | 0.4335 ms | 0.5041 ms | 0.6121 ms | 49.91% (Keccak-f1600, shared primitive)* | 25 KeyGen • 25 Encaps • 10 Decaps |
| ML-KEM-1024 (High-Sec) | 0.6266 ms | 0.7072 ms | 0.8541 ms | 49.96% (SHAKE-256, shared primitive)* | 25 KeyGen • 25 Encaps • 10 Decaps |
* The 768 and 1024 rows report diffusion for the underlying Keccak/SHAKE primitives shared identically across all three parameter sets — not an independently measured full-ciphertext avalanche test for that specific parameter set. Full ciphertext-level avalanche testing (input bit flip → % of output ciphertext bits changed) was measured directly for ML-KEM-512.
Separately, byte-value uniformity was verified via Shannon entropy density across 2,000 pooled ML-KEM-512 ciphertexts (12,288,000 bits): 7.9999 / 8.0000 bits/byte — statistically indistinguishable from uniform random output.
Why Choose Shatachandra Shield?

Sub-Millisecond Overhead
AVX2-vectorized arithmetic routines deliver true post-quantum encryption at conventional TLS speeds with no throughput bottleneck.
True Zero-Trust Isolation
Unauthenticated or anomalous requests are quarantined at the gateway boundary before consuming cryptographic compute cycles.
Deterministic Conformance
Byte-exact implementation verified directly against official NIST ACVP known-answer test vectors and Strict Avalanche Criteria.
