Strategic Health Authority. The local headquarters of the NHS, responsible for ensuring that national priorities are integrated into local plans and for ensuring that Primary Care Trusts (PCTs) are performing well. They are the link between the Department of Health and the NHS.

Strategic Health Authority / Special Health Authority

Statutory Harbour Authority – a body responsible for improving, maintaining and managing a harbour under the Harbours Act (1964)

Strategic health authority – manages the NHS at local level. SHAs are responsible for: developing plans for improving health services in their local area, making sure local health services are of a high quality and performing well, increasing the capacity of local health services, and making sure national priorities are integrated into local health service plans.

Secure Hash Algorithm. The current approved hash algorithm produces a message digest of 160 bits.

Secure Hash Algorithm. An algorithm that assures data integrity by generating a 160-bit cryptographic message digest value from given data. If as little as a single bit in the data is modified, the Secure Hash Algorithm checksum for the data changes. Forgery of a given data set in a way that will cause the Secure Hash Algorithm to generate the same result as that for the original data is considered computationally infeasible. An algorithm that takes a message of less than 264 bits in length and produces a 160-bit message digest. The algorithm is slightly slower than MD5, but the larger message digest makes it more secure against brute-force collision and inversion attacks.

secure hash, or message digest algorithm adopted as a Federal Information Processing Standard.

Secure Hash Algorithm. A U.S. standard published by the National Institutes of Sciences and Technology.

Secure Hash Algorithm— similar function as MD5. Simple Mail Transfer Protocol See SMTP.

A one way hash put forth by NIST. SHA is closely modeled after MD4 and produces a 160-bit digest. Because SHA produces a 160-bit digest, it is more resistant to attacks than 128-bit hashes (such as MD5), but it is slower. RFC 2404 documents the latest version of SHA.

Secure Hash Algorithm. A hash algorithm used for data authentication and to verify integrity of the communication.

Also known as killing breath, sha chi refers to the negative energy that is caused by sharp angles and hostile structures. There are numerous cures for these issues, including placement of mirrors, crystals and plants to deflect and soften this harmful energy.
