The patch set replaces the LFSR conditioning function of the Jitter RNG
with SHA-3 256. This change requires also a new test interface to
analyze the raw unconditioned noise data.

Albeit the test interface can be used directly with dd, a small helper
tool is provided at [1] which can be used to perform the collection
of raw entropy. The analysis of the data can be done with your favorite
tool. Or you may use the helper in [2] which uses the NIST SP800-90B
tool for entropy rate measurement.

Using the kernel crypto API, the SHA3-256 algorithm is used as
conditioning element to replace the LFSR in the Jitter RNG. All other
parts of the Jitter RNG are unchanged.

The application and use of the SHA-3 conditioning operation is identical
to the user space Jitter RNG 3.4.0 by applying the following concept:

- the Jitter RNG initializes a SHA-3 state which acts as the "entropy
  pool" when the Jitter RNG is allocated.

- When a new time delta is obtained, it is inserted into the "entropy
  pool" with a SHA-3 update operation. Note, this operation in most of
  the cases is a simple memcpy() onto the SHA-3 stack.

- To cause a true SHA-3 operation for each time delta operation, a
  second SHA-3 operation is performed hashing Jitter RNG status
  information. The final message digest is also inserted into the
  "entropy pool" with a SHA-3 update operation. Yet, this data is not
  considered to provide any entropy, but it shall stir the entropy pool.

- To generate a random number, a SHA-3 final operation is performed to
  calculate a message digest followed by an immediate SHA-3 init to
  re-initialize the "entropy pool". The obtained message digest is one
  block of the Jitter RNG that is returned to the caller.

Mathematically speaking, the random number generated by the Jitter RNG
is:

aux_t = SHA-3(Jitter RNG state data)

Jitter RNG block = SHA-3(time_i || aux_i || time_(i-1) || aux_(i-1) ||
                         ... || time_(i-255) || aux_(i-255))

when assuming that the OSR = 1, i.e. the default value.

This operation implies that the Jitter RNG has an output-blocksize of
256 bits instead of the 64 bits of the LFSR-based Jitter RNG that is
replaced with this patch.

The patch also replaces the varying number of invocations of the
conditioning function with one fixed number of invocations. The use
of the conditioning function consistent with the userspace Jitter RNG
library version 3.4.0.

The code is tested with a system that exhibited the least amount of
entropy generated by the Jitter RNG: the SiFive Unmatched RISC-V
system. The measured entropy rate is well above the heuristically
implied entropy value of 1 bit of entropy per time delta. On all other
tested systems, the measured entropy rate is even higher by orders
of magnitude. The measurement was performed using updated tooling
provided with the user space Jitter RNG library test framework.

The performance of the Jitter RNG with this patch is about en par
with the performance of the Jitter RNG without the patch.

* [PATCH 2/2] crypto: jitter - add interface for gathering of raw entropy

  To: linux-crypto, herbert; +Cc: Vladis Dronov, Marcelo Cerri

The test interface allows a privileged process to capture the raw
unconditioned noise that is collected by the Jitter RNG for statistical
analysis. Such testing allows the analysis how much entropy
the Jitter RNG noise source provides on a given platform. The obtained
data is the time stamp sampled by the Jitter RNG. Considering that
the Jitter RNG inserts the delta of this time stamp compared to the
immediately preceding time stamp, the obtained data needs to be
post-processed accordingly to obtain the data the Jitter RNG inserts
into its entropy pool.

The raw entropy collection is provided to obtain the raw unmodified
time stamps that are about to be added to the Jitter RNG entropy pool
and are credited with entropy. Thus, this patch adds an interface
which renders the Jitter RNG insecure. This patch is NOT INTENDED
FOR PRODUCTION SYSTEMS, but solely for development/test systems to
verify the available entropy rate.

Access to the data is given through the jent_raw_hires debugfs file.
The data buffer should be multiples of sizeof(u32) to fill the entire
buffer. Using the option jitterentropy_testing.boot_raw_hires_test=1
the raw noise of the first 1000 entropy events since boot can be
sampled.

This test interface allows generating the data required for
analysis whether the Jitter RNG is in compliance with SP800-90B
sections 3.1.3 and 3.1.4.

If the test interface is not compiled, its code is a noop which has no
impact on the performance.

The patch set replaces the LFSR conditioning function of the Jitter RNG
with SHA-3 256. This change requires also a new test interface to
analyze the raw unconditioned noise data.

Albeit the test interface can be used directly with dd, a small helper
tool is provided at [1] which can be used to perform the collection
of raw entropy. The analysis of the data can be done with your favorite
tool. Or you may use the helper in [2] which uses the NIST SP800-90B
tool for entropy rate measurement.

[2] https://github.com/smuellerDD/jitterentropy-library/tree/master/tests/raw-entropy/validation-runtime-kernel

Changes v2:

- fix use-after-free by switching shash_desc_zero and crypto_free_shash
  in jent_mod_init reported by kernel-test-robot

Using the kernel crypto API, the SHA3-256 algorithm is used as
conditioning element to replace the LFSR in the Jitter RNG. All other
parts of the Jitter RNG are unchanged.

The application and use of the SHA-3 conditioning operation is identical
to the user space Jitter RNG 3.4.0 by applying the following concept:

- the Jitter RNG initializes a SHA-3 state which acts as the "entropy
  pool" when the Jitter RNG is allocated.

- When a new time delta is obtained, it is inserted into the "entropy
  pool" with a SHA-3 update operation. Note, this operation in most of
  the cases is a simple memcpy() onto the SHA-3 stack.

- To cause a true SHA-3 operation for each time delta operation, a
  second SHA-3 operation is performed hashing Jitter RNG status
  information. The final message digest is also inserted into the
  "entropy pool" with a SHA-3 update operation. Yet, this data is not
  considered to provide any entropy, but it shall stir the entropy pool.

- To generate a random number, a SHA-3 final operation is performed to
  calculate a message digest followed by an immediate SHA-3 init to
  re-initialize the "entropy pool". The obtained message digest is one
  block of the Jitter RNG that is returned to the caller.

Mathematically speaking, the random number generated by the Jitter RNG
is:

aux_t = SHA-3(Jitter RNG state data)

Jitter RNG block = SHA-3(time_i || aux_i || time_(i-1) || aux_(i-1) ||
                         ... || time_(i-255) || aux_(i-255))

when assuming that the OSR = 1, i.e. the default value.

This operation implies that the Jitter RNG has an output-blocksize of
256 bits instead of the 64 bits of the LFSR-based Jitter RNG that is
replaced with this patch.

The patch also replaces the varying number of invocations of the
conditioning function with one fixed number of invocations. The use
of the conditioning function consistent with the userspace Jitter RNG
library version 3.4.0.

The code is tested with a system that exhibited the least amount of
entropy generated by the Jitter RNG: the SiFive Unmatched RISC-V
system. The measured entropy rate is well above the heuristically
implied entropy value of 1 bit of entropy per time delta. On all other
tested systems, the measured entropy rate is even higher by orders
of magnitude. The measurement was performed using updated tooling
provided with the user space Jitter RNG library test framework.

The performance of the Jitter RNG with this patch is about en par
with the performance of the Jitter RNG without the patch.

* [PATCH v2 2/2] crypto: jitter - add interface for gathering of raw entropy

  2 siblings, 0 replies; 13+ messages in thread
From: Stephan Müller @ 2023-04-10 20:55 UTC (permalink / raw)
  To: linux-crypto, herbert; +Cc: Vladis Dronov, Marcelo Cerri

The test interface allows a privileged process to capture the raw
unconditioned noise that is collected by the Jitter RNG for statistical
analysis. Such testing allows the analysis how much entropy
the Jitter RNG noise source provides on a given platform. The obtained
data is the time stamp sampled by the Jitter RNG. Considering that
the Jitter RNG inserts the delta of this time stamp compared to the
immediately preceding time stamp, the obtained data needs to be
post-processed accordingly to obtain the data the Jitter RNG inserts
into its entropy pool.

The raw entropy collection is provided to obtain the raw unmodified
time stamps that are about to be added to the Jitter RNG entropy pool
and are credited with entropy. Thus, this patch adds an interface
which renders the Jitter RNG insecure. This patch is NOT INTENDED
FOR PRODUCTION SYSTEMS, but solely for development/test systems to
verify the available entropy rate.

Access to the data is given through the jent_raw_hires debugfs file.
The data buffer should be multiples of sizeof(u32) to fill the entire
buffer. Using the option jitterentropy_testing.boot_raw_hires_test=1
the raw noise of the first 1000 entropy events since boot can be
sampled.

This test interface allows generating the data required for
analysis whether the Jitter RNG is in compliance with SP800-90B
sections 3.1.3 and 3.1.4.

If the test interface is not compiled, its code is a noop which has no
impact on the performance.

Correct. Thanks a lot for the catch. I will update this.

The patch set replaces the LFSR conditioning function of the Jitter RNG
with SHA-3 256. This change requires also a new test interface to
analyze the raw unconditioned noise data.

Albeit the test interface can be used directly with dd, a small helper
tool is provided at [1] which can be used to perform the collection
of raw entropy. The analysis of the data can be done with your favorite
tool. Or you may use the helper in [2] which uses the NIST SP800-90B
tool for entropy rate measurement.

[1] https://github.com/smuellerDD/jitterentropy-library/tree/master/tests/raw-entropy/recording_runtime_kernelspace

[2] https://github.com/smuellerDD/jitterentropy-library/tree/master/tests/raw-entropy/validation-runtime-kernel

Changes v3:

- fix jent_kcapi_init: error code for jent_entropy_collector_alloc now
  properly cleans up the state

- fix jent_kcapi_init: initialize lock at the beginning as it is used in
  error code path function jent_kcapi_cleanup

- editorial change: update description in MODULE_PARM_DESC in patch 0002

Changes v2:

- fix use-after-free by switching shash_desc_zero and crypto_free_shash
  in jent_mod_init reported by kernel-test-robot

Using the kernel crypto API, the SHA3-256 algorithm is used as
conditioning element to replace the LFSR in the Jitter RNG. All other
parts of the Jitter RNG are unchanged.

The application and use of the SHA-3 conditioning operation is identical
to the user space Jitter RNG 3.4.0 by applying the following concept:

- the Jitter RNG initializes a SHA-3 state which acts as the "entropy
  pool" when the Jitter RNG is allocated.

- When a new time delta is obtained, it is inserted into the "entropy
  pool" with a SHA-3 update operation. Note, this operation in most of
  the cases is a simple memcpy() onto the SHA-3 stack.

- To cause a true SHA-3 operation for each time delta operation, a
  second SHA-3 operation is performed hashing Jitter RNG status
  information. The final message digest is also inserted into the
  "entropy pool" with a SHA-3 update operation. Yet, this data is not
  considered to provide any entropy, but it shall stir the entropy pool.

- To generate a random number, a SHA-3 final operation is performed to
  calculate a message digest followed by an immediate SHA-3 init to
  re-initialize the "entropy pool". The obtained message digest is one
  block of the Jitter RNG that is returned to the caller.

Mathematically speaking, the random number generated by the Jitter RNG
is:

aux_t = SHA-3(Jitter RNG state data)

Jitter RNG block = SHA-3(time_i || aux_i || time_(i-1) || aux_(i-1) ||
                         ... || time_(i-255) || aux_(i-255))

when assuming that the OSR = 1, i.e. the default value.

This operation implies that the Jitter RNG has an output-blocksize of
256 bits instead of the 64 bits of the LFSR-based Jitter RNG that is
replaced with this patch.

The patch also replaces the varying number of invocations of the
conditioning function with one fixed number of invocations. The use
of the conditioning function consistent with the userspace Jitter RNG
library version 3.4.0.

The code is tested with a system that exhibited the least amount of
entropy generated by the Jitter RNG: the SiFive Unmatched RISC-V
system. The measured entropy rate is well above the heuristically
implied entropy value of 1 bit of entropy per time delta. On all other
tested systems, the measured entropy rate is even higher by orders
of magnitude. The measurement was performed using updated tooling
provided with the user space Jitter RNG library test framework.

The performance of the Jitter RNG with this patch is about en par
with the performance of the Jitter RNG without the patch.

  To: linux-crypto, herbert; +Cc: Vladis Dronov, Marcelo Cerri

The test interface allows a privileged process to capture the raw
unconditioned noise that is collected by the Jitter RNG for statistical
analysis. Such testing allows the analysis how much entropy
the Jitter RNG noise source provides on a given platform. The obtained
data is the time stamp sampled by the Jitter RNG. Considering that
the Jitter RNG inserts the delta of this time stamp compared to the
immediately preceding time stamp, the obtained data needs to be
post-processed accordingly to obtain the data the Jitter RNG inserts
into its entropy pool.

The raw entropy collection is provided to obtain the raw unmodified
time stamps that are about to be added to the Jitter RNG entropy pool
and are credited with entropy. Thus, this patch adds an interface
which renders the Jitter RNG insecure. This patch is NOT INTENDED
FOR PRODUCTION SYSTEMS, but solely for development/test systems to
verify the available entropy rate.

Access to the data is given through the jent_raw_hires debugfs file.
The data buffer should be multiples of sizeof(u32) to fill the entire
buffer. Using the option jitterentropy_testing.boot_raw_hires_test=1
the raw noise of the first 1000 entropy events since boot can be
sampled.

This test interface allows generating the data required for
analysis whether the Jitter RNG is in compliance with SP800-90B
sections 3.1.3 and 3.1.4.

If the test interface is not compiled, its code is a noop which has no
impact on the performance.
